1978 Caprice LQ9 Swap (Approx 4,000 lbs with me in it)
Cam Only LQ9
EPS Cam (234/246 @ .050, .602/.607 on a 111 LSA) (Link: http://www.engpwrsys.com/index.php?a...d&productId=10 )
LS6 Intake
ARP Rod Bolts
Headman Headers (Full Length with crappy lil 1.5" primary's)
TH400 Trans
Redneck Racing 4500 Stall
GM 10 Bolt
Converter seemed to slip on the Dyno, only 388rwhp/368rwtq, which seems low, but it was through a large stall converter, 15 psi drag radials and a TH400. The track ET and MPH put the car at well over 400 Rwhp as per the Wallace Racing Calculator. (Even though my car doesn't have a 1st gear when it made those times.)
(Link to Calculator: http://www.wallaceracing.com/hpcalculatorquarter.php )
First and Second trip to the track, 10 bolt gave up the ghost )blew rear end each time I went to the track), but ran a 12.0@111 with a lazy 1.6 60'.
Should be able to crack the 11's if I can the rear end to stay together.

Patrick G spec'd Comp cam 231/231 .612/.604 111 +4
Untouched stock heads
Nick Williams tune
ported stock throttle body
LS6 intake
Fluidampr 10% underdrive pulley
Comp Cams Adjustable Timing Chain
PRC Double Valvesprings & Titanium retainers
Mac midlengths with custom y-pipe and Flowmaster merge
E-cutout
Hooker catback
Six Speeds Inc Stage 4 T56
Denny's Nitrous Ready driveshaft
Textralia Exoskel clutch
Moser axles
Stock 3.42s for now, 3.73s already in spare rear waiting on a free weekend to install.
394rwhp/389rwtq
Fairly rough idle, has a little surge when cold, but otherwise drives just like a stock cam. Previous owner swapped cams, and so far in the 9 months I've owned it I've been VERY pleased. I could DD this car no problem, especially with a less aggressive clutch. I think it has alot to do with the tune, it idles at 900rpm dead on without any hunting.

took off the SLP 2OTL and my Ypipe, that made the 441w.
Put on 2 short strait thew mufflers with a turn down beofre the rear end, stiffer pushrods and shimmed the valvesprings. Put down 450whp, everything else the same. Still have some other things to do

Drivability is awesome in rain, dry, cold, or hot. Idles and drives perfect with the a/c on. Sounds great with the Corsa that was recently put on.
Video of the car in sig. Going to get a new video up soon that one is 2 1/2 yrs old. Many different things done now.

-M6 with SPEC stg. 2 clutch
-Stock heads
-LT's + ORY + Cutout
-Lid + K&N + descreened MAF (The latter two were good for 8 rwhp, dyno proven)
-P&P throttle body
400.81 rwhp / 374.07 tq
Pulls hard as hell after 4K and makes a steady 400whp from 6200-6500.
Made 340 rwhp without the cam, ORY (had high flow cats), and screened MAF.

My TrickFlow cam produced 81 hp over base with closed exhaust. It has very poor street manners. Torque and power curves bloom late in the rpm range (4000 rmp to 6700 rpm). The 4.56 gears help to compensate for low end torque somewhat. The MT Dr's when hot aids higher-rpm launches. The McCloud RST twin-disk clutch allows good control at launch.
I love the idle. The radical lope is awesomely wicked.
