Darcy has a fun summer ahead of him.
5.3 Swapped Asuna Sunrunner 
You may have seen the picture in an older post of a yellow Asuna getting a 5.3. Well its almost ready to start now………………..
Maggie Charged L33
Facebook and forums make the world a smaller place,I met the owner of this truck online. He installed a Magnuson supercharger package on his l33 Silverado. While the fit is identical, the extra compression did not work well with supplied hand held “canned” tune. I worked with him remote tuning from Georgia to get the truck dialed in to where it needs to be.
1999 Turbo Suburban 
At over 7000 lbs this full size Suburban was never going to be a race car. In 1999 the 5.3 was only rated at 275hp flywheel so with this much weight it had a hard a time climbing hills without being at 4000+ rpm in 2nd gear. So the owner put a 212/218 comp cam and turbo kit on it and brought it to me for a tune. At 8psi the Suburban now pulls away strong from the lights and will climb the west side hill in 4th gear without effort, even on 35″ tires.
Jordan’s Square Body Turbo Build 
Another local turbo truck in build, shooting for a first start on October 15. Square body fans are going to be happy! More to come.
Update to Martin’s truck 
560hp/566tq, this is the stoutest 4.8 I have ever worked on. Truck is a blast to drive, definitely going to hurt some feelings! Stock unopened 4.8 with Comp 224/230 cam, Edelbrock carb intake with elbow, Trick turbo kit, Precision 76/75. Launching off the trans brake it hooks and goes, looking forward to a track pass next year. A Boost Leash and Devils Own meth kit are on the winter to do list so we can turn this one up some more in the spring.
My own personal tow rig 
I put a 212/218 cam, Cold air intake, shorty headers, and did a tune. I finally got an opportunity to put it on the dyno today. 358hp/423tq to the wheels on a conservative 87 octane tune. Im pretty happy considering the factory rating was 320hp/360tq at the flywheel. Drives like stock and I can fill it up anywhere.
Steven’s 2014 Silverado 
Steven brought it to me complaining about lack of bottom end, he says it has no problem spinning the 33″ tires now.
Luke’s 1982 K10 Blazer 5.3/4l60 swap
Luke still has a ways to go on his 1982 K10 project, but the engine runs! I provided him with an e38/t42 pcm combo and stand alone programming to run his 2008 5.3/4l60.
Randy’s Asuna Sunrunner 4.8 Swap 
Wish I had more pics of this one, but for now this is it. 1991 Asuna Sunrunner with a 4.8 4l60 swap. It currently has 5.13 gears while he looks for an 8.8 with 3.73’s. First drive should be entertaining!
Joe’s Avalanche 
Joe had added a few bolt on’s and wanted to tune updated to to take advantage of it. He also wanted to transmission not to come out of 6th so easily while on the highway. For a man in his 70’s hes not afraid to use the go pedal!
Eric’s 1992 Chevy Silverado 5.3 Swap 
Eric put a 5.3 with 700r4 into his 92 Chevy. I believe its his daily.
Dan’s 1978 Chevrolet C10 Stepside with 5.3 swap 
Dan has swapped a stock LM7 5.3 into his square body stepside on air. Look for this cruiser on a road near you soon!
Cody’s 1992 6.0 4l80 Swap
The truck sounds bad ass. 2006 6.0 4l80 swap with Tick SNS stage 3 235/243 on a 111+2. Cant wait for the body work to be done and this thing to hit the streets.
Dan’s LS Powered Rat Rod 
Dan has done a lot of work to this Model A. It has a 5.3l with a comp 235/243 on a 113, Holley tunnel ram with dual throttle bodies, 4.56 gear, and a 2500 stall. At 3200lbs without driver the roughly 350hp engine moves this car very well.
Sandy’s 1967 Beaumont with LM7 5.3 4l60 
Sandy pulled the 454 out in favor of a 5.3 4l60 combo that was fun, fuel efficient, and reliable. Hes still finishing up a few things, but the car runs and cruises along very nicely.
Martin’s 2004 Silverado 4.8 with Precision 76/75 
Martin has done his own wheel tubs and built his own 4 link on this truck. He added a pre-built turbo kit with a precision 76/75 turbo. Exciting things to come from this truck this summer. Hoping to have some entertaining videos in the near future!
John’s 1968 C10 6.0 4l60 
John took a LQ4 short block and put an LS3 top on it along with a 219/233 cam, headers, and 2400 stall. Truck is fresh out of the body shop with new rims and tires that are not going to last long.
James 1968 C10 6.0 6l80 Swap 
James installed a 2010 LY6 6.0 and 6l80 into his C10 last summer and brought it to FLP and myself for finishing. This year he brought it back for a BTR Stage 2 PDS cam(227/242 .614/.592 122+6) and accompanying tuning to go with his 4.10 Trailblazer SS differential. 4.10 gears and a 6l80 make the first gears just about useless as you go sideways with the tires up in smoke.
Blaine’s 6.0 swap into Toyota mini mud truck 
This little truck will be a lot fun when he gets it done.
Curtis’s 5.3 swap 
Curtis’s sharp looking OBS is getting an upgrade, hope to have some more pic’s and video as this one progresses.
Ewan’s Jaguar getting an LQ9 
Ewan is putting an LQ9 6.0 into this Jaguar XJ8 for a new lease on life.
Thomas’s 1980 Malibu 5.3 swap 
Thomas has put a 5.3 with a 216/220 cam into his Malibu. He has future plans for a turbo.
Rick’s 2001 Firebird with Brian Tooley stage 2 Cam 
Twin to another car I’ve worked on. This 2001 T/A went into Finish Line Performance for full exhaust and a Brian Tooley stage 2 ls1 cam. Car dynoed at 330 before FLP’s upgrades and 413 (450 corrected) today after the upgrades and my tuning.
Darcy’s 1998 Jeep TJ 5.3 L33 Swap 
Darcy is transplanting a 5.3 L33 4l65 combo into his Jeep TJ for little more umph. Little wiring still to go, but this thing should be ripping around soon!
Aaron’s Sierra 
Aaron’s RCSB Sierra started life as a v6 truck. He swapped an LS V8 with 4l80 in its place. I provided him a tune and segment swap to match his modifications. Truck is running/driving now and Arron is enjoying his work.
Dustin’s 1980 GMC C20 6.0 swap 
1980 GMC C20 is getting an update with a 6.0. While it still tips the scales on the heavy side he has plans to shock a few friends.
Matthew’s 5.3 swap BMW E36 
With a 5.3 and a Muncie 4 speed this car is destined to drift.
Bryce’s 2005 RCSB 224/228 
Bryce just finished a fresh build on his 5.3 including Patriot Heads and a 224/228 on a 112 cam. A full tune with lean cruise gives this cammed 5.3 very nice street manners.
John’s 6.0 Swap 1968 Chevy Truck 
LQ4 with LS3 heads, comp cam, and whole lot of fun.
Max’s Hills Hot Rods Square Body 
Max bought this Hills Hot Rods truck with tbi/700r4 combo. He then updated it to 5.3 with a 228/228 on a 110 cam and 4l60. Complete tune with lean cruise. Truck sounds good, video posted further down.
Darrens 1938 5.3 Swap Chevy 
5.3 punched out to 5.7 with comp 224/224 cam swapped into 1938 chev. Beautiful car.
Henry’s Super Short Box 6.0 Swap 
6.0 6l80 with crew cab short box, very short truck.
Keenan’s 350z LS3 Swap 
What was supposed to be a day of tuning turned into a day with a soldering iron and wiring diagram. In the end we got the 350z to start, run, and drive. Keenan still had a few bugs to work out but we solved most of what ailed it and he was able to get it home.
Chris’s Ratty L33 Nova 
Chris’s 1972 Nova has been built with his own two hands(and some borrowed hands of good friends). Car features some Hotchkis suspension upgrades, 3:73 posi rearend, built 4l60 with 3000 stall, and an L33 5.3 aluminum engine with 232/234 on a 112 cam. Supporting intake and exhuast round out the package. The car HAULS! Road trips so far have shown 21 mpg, I think it has more in it if we can just get Chris to keep his foot out of it…………………….
Update: A recent Dyno session has this combo at 349hp and 341tq. 12.95@107
Michael’s V6 Conversion 
Originally a V6, this car transitioned from home made 6.0 rear mount turbo with th350 to a 403 front mount. Michael did all of his own fab work. Using a ebay 78mm and our tuning at 12 psi this car made 638 rwhp.
Tristan’s 5.3 swap Mustang 
Tristan’s 95 Mustang with 5.3 swap. Unfortunately the transmission didn’t hold up long enough to finish tuning this summer. Try again with another transmission. PRC heads and a BTR cam are being added with the new astro t5.
Romeo’s 2001 Silverado 6.0 swap 
Romeo’s 2001 Silverado. 6.0 swap, cam 228/230 on a 112, headers, converter, and a whole lot of fun.
Mark’s 223/231 Avalanche 
Marks Avalanche is free of all the cladding that these models typically suffer. And its my favorite gm color! 5.3 with 223 231 on a 112 cam. This thing has a nasty idle, but is smooth and nice to drive. The 5.3 makes the speedo climb at an impressive rate. Looks great and goes too!
The last tank Mark achieved 19us/22.8imp mpg with Lean Cruise enabled.
Gords 1981 GMC LS powered RCSB 
I did an LS swap into this truck in the summer of 2010. Turned into quite a strong performer. The little 4.8 gets awesome mileage and easily outperforms the small block 350 it replaced. The truck is used as a hunting wagon, pulls the sled trailer in the winter, and has a plow attached to clear the snow from the acreage in the winter. Gord says he still gets offers to buy it every where he goes.
Kurtis’s 1967 Chevelle with ATK 489 
1967 Chevelle is a real head turner. The engine was shipped from ATK with a very rich tune and the car was very lazy. We rejetted the carb and made the other required adjustments and it woke right up. His wife had not previously been afraid of the car, the first time he stepped on it after the tune she said he had to warn her before he did that!
2003 Shortbox 6.0 Swap 
Truck was a well used 4.8 base model to start with. I had to spend a lot of time diagnosing this truck as it had a number of problems including failed O2 sensors and MAF. The owner had it painted, cat skin seats added, and a 6.0 with 228/228 on a 110 installed. Truck looks sharp, sounds great, and is very fun to drive.
Geoff’s Confused Silvia 
Geoff’s 1991 Silvia with a 6.0 L76 / t56 swap. Car has been traction limited low 11’s at 135 mph.
Jame’s 1970 Chevrolet with LY6 and 6L80 swap 
This shortbox is a lot of fun to drive and gets a lot of attention. 6 speed auto and 6.0 light the tires quite easily.
Travis’s 210/220 pullied full exhaust GTP 
2002 Pontiac Grand Prix GTP with top swap, pullied, speed daddy gtp headers, and comp 210/220 cam. Very fun daily.
Lloyds “Mr Cranky” shop truck 
LQ4 with comp 222/222 on a 112 cam and full exhaust. Made 376 to the tire on the dyno.
