Jeff Gilbert's 96 TA is dangerously close to 8 second ET's! - As seen making a mockery of a turbo honda ("I need 20 car lengths...") on Pink's, Jeff's 1996 Trans-Am is brutally quick. Soon to be one of only a few to break into the 8 second range with a true LT1 powered LT1 f-body, Jeff has done an excellent job getting this car together and sorted out. It's powered by a 396cid LT1 shortblock with our 215cc CNC'd TFS LT1's, a "Street/Strip" ported GM LT1 intake manifold, and still utilizes a hydraulic roller cam and the GM PCM! Click HERE for a quick Dyno video or HERE to check out video of his 9.06 @ 151.48mph pass!
Mike Harvey's Street/Strip Z28 runs well into the 10's Naturally Aspirated! - Mike has taken the time to put a superb combination together for his 1995 Z28. With Mike's determination and skill this car will surely continue to impress as the weather comes around to us this fall. With an 11.5:1 compression 383 LT1 shortblock, Ai 215cc TFS LT1 heads, converted ProRam intake manifold, and a custom Ai solid roller this is one screaming powerplant. The driveline is comprised of a GM TH350, 4000rpm stall converter, and 4.56's in a moser 12bolt. With some bolt-on BMR suspension parts and Mike doing his own tuning with a new FAST XFI system we expect great things out of this car at it's current 3500lb raceweight. Thus far Mike has managed to run into the 10.6's @ 128.6mph at his local KY track. Check out video of one of his passes HERE!
Aleks' NA 355 LT1 - 480rwhp/419rwtq SAE - Aleks asked for a topend to transform his over-bore rebuild into a weapon and the numbers speak for themselves. With a much fatter torque curve than most strokers this is one hot 355. His setup consists of the same 200cc CNC LT1's & Street/Strip Ported LT1 Manifold Rick Abare uses to break records. With a very drivable solid roller setup this car is sure to get some attention prowling the streets & at the track. On its initial outing, inlet restricted to 450rwhp, this full weight M6 car with full accessories (A/C, Power Steering, stereo, subs, etc.) went 11.3X's @ 123.5in street trim. Updates as soon as Aleks dials in the tune & replaces the 12-bolt he mangled. Expect extremely low 11's at worst & over 400rwtq by 3500rpm. Here are the current dyno graphs:
Another Full Weight 11sec LT1 Street Car! - Steve B. has made 428rwhp & 375rwtq SAE with a 355 rebuild, stock intake manifold, one of our streetable HR grinds, 190cc CNC'd LT1 castings, and a Moser 9" rear end on 93 octane pump fuel. This is a full weight street car with 3665lb Raceweight!. With Steve's great tuning & driving ability he's run bests of 7.451 @ 94.45mph in the 1/8th and 11.528 @ 125.31mph in good air. This is a gain of .8 seconds, 9mph, and 50hp+ over his previous best with the same shortblock & car using a competitors ported 205cc LT1 topend! Check out some timeslips from a few of Steve's many 11-second passes!
96capriceMGR's Record Setting 4200lb B-Body! - Dwayne's daily driven Caprice is turning in great results at the track. Even better than most B-bodies with 383-396 strokers, more compression, head & camshaft! With a GM stock lt1 shortblock (NOT a rebuilt "stock 350"), the 190cc CNC LT1's and one of our small mild daily driver HR cams not only has Dwayne run 11.95 at 113mph in the quarter with full exhaust, but it's still daily driven! Most unbelievable is that the cam is small enough that Dwayne actually tows his small boat with the car. With the tune dialed in & intake/exhaust sorted out Dwayne is expecting 11.80's in good air, all on the 100,000+ mile factory stock shortblock! Click HERE to check out his timeslips!
Bock's Street & Road Race Beast - How about OVER 400rwtq by 2800rpm with 440 peak rwtq and 445 peak rwhp from one of our NA LT1 packages? This is a 383 with our proven 190cc CNC LT1 package with full exhaust on pump fuel, a mild 230/236 .560" hydraulic and only 11.3:1 static compression. Many may not believe it, but this is actually a mild setup specifically tailored to handle the abuse of road course trackdays and the rigors of daily driving. Check out the Dyno Sheet HERE!
Matt's Street/Strip 383: 434rwhp/417rwtq SAE - With the guys at Speed Inc. doing the tuning, Matt's street/strip car made great power on pump fuel with full exhaust & 4.10's out back. With our 190cc CNC LT1's, an unported manifold, and our ultimate 383 street/strip cam Matt's making more torque at 3000rpm than many 383 LT1's produce peak at any rpm. With monstrous torque and power from 3000-6500rpm this is one of our best running packages for full weight cars & even exhibits fantastic drivability. Track times to follow shortly! Click HERE to check out Matt's Dyno Graph!
574rwhp/561rwtq SAE on Pump Fuel! - Tory's daily driver Z has put down great power on 93 octane pump fuel. This setup consists of our 190cc CNC LT1's on a basic 383cid LT1 shortblock, with a 230deg HR camshaft, and a full exhaust system. Tory runs a Vortech S-Trim with No Intercooler at only 9psi for a safe & reliable street brawler. Click HERE to check out Tory's dynograph.
482rwhp Stock 350LT1 on Pump Fuel! - Tim Glass' daily driver Z made great power on 93 octane pump fuel. This setup consists of our 200cc TFS LT1's on a Stock 350cid LT1 shortblock, a 224deg HR camshaft, and a full exhaust system with cats! Tim runs a Vortech S-Trim at a mere 6psi. Click HERE to check out Tim's dynograph.
FI's 9 Second LT1 Street Car! - Forced Inductions has pounded the rollers with 1012rwhp & 909rwtq SAE with their PTK 88mm Turbo setup on an ordinary budget Eagle 355 rebuild. This street terror runs our 200cc ported GM lt1 castings, a 218/218 .544/.544 camshaft, 12-bolt rear end, and a D&D T56 6-speed. This is a full weight street car with 3680lb Raceweight!. With Jose @ FI's expertise it's run a best of 122mph in the 1/8th and 9.871 @ 156.74mph in the quarter! The fastest LT1 powered LT1 F-body ever! Click HERE for a timeslip of this record setting pass!
Russ' low 11sec LT1 Street Car! - Russ Ethridge has managed 444rwhp & 397rwtq STD (425/376 SAE) with a budget 355 rebuild, stock intake, one of our HR grinds, Fully ported LT1 castings, through full exhaust, and a Moser 12-bolt rear end on 92 octane pump fuel. The car is approximately 100lb lighter than full weight (No AC). We're pretty pleased, as this was done with a topend ignition miss (see dyno sheet). In this configuration the car's managed 7.20's @ 96mph in the 1/8th and 11.40's @ 120mph in the quarter. Where will it peak? Approximately 6700rpm with another 15-20rwhp.

Brian's dyno sheets can be seen here: STD SAE
Waswa's 95 6-Speed Z28 rolled 412rwhp through full exhaust with our 185cc LT1 Head Package, a GM847 Hydraulic Roller, and a mail-order program on a stock 72,000 mile LT1 shortblock. Here is his dyno sheet. SAE corrected, the numbers were still 405rwhp & 365rwtq. With this setup Waswa has managed 12.00 @ 116.64mph! For updates, check out Waswa's site here. Thanks Waswa!
Nick's Daily Corner Carver -How does 411rwhp SAE and 370rwtq through 1-5/8" shorties and a full SLP catback from a stock LT1 shortblock with 98,000 miles, 91 octane MTBE fuel, and a 230/238-112 Hydraulic sound? Check out the Dyno Sheet HERE! You can also head over to Nick's 94Z28 site here. Thanks for the numbers Nick!
Eric's 95 Z-28 -Eric Buss rolled 401rwhp SAE and 378rwtq through MAC headers, and a Full catback exhaust. That's 420rwhp/396rwtq STD! Eric is running a 355cid LT1 with our Full Port LT1's, an untouched intake manifold, and our 211-HR grind camshaft. To date his best track time at full weight has been 12.1@117mph on a 1.98 60'.

The Doctor Says:
Hey Guys,
Heads looked great, and arrived within about 3 weeks. When tuning this combo, keep in mind it was my first time on the dyno, much less tuning a combo like this. On the dyno sheets I sent to you, you'll see that past 5900 RPM power doesn't rise or fall, it just levels off which I couldn't figure out. What I do know now is that the rotor inside the Optispark unit was dying, and I was running too much advance at high RPM, as well as a tad rich up top.
Alot of people didn't believe it was possible to make this much power with shorty headers, obviously this isn't true. With long tubes and the Optispark (cap and rotor) up to snuff, this should have turned 430rwhp SAE if not perhaps more, all on a stock bottom. No aftermarket rod bolts or anything fancy.
Thanks guys!
William
