Had some issues with no vacuum, and two step was turned all the way down to 2500rpms. I also banged the rev limiter on the 1-2 shift which killed some momentum. Also could not spray car after the one pass because the cheapy throttle bracket was flexing like mad. All in all, not a bad first day out in some heat.
The weight argument it stupid, compare a Warhawk LS motor to a all aluminum BBC, the weight difference is worth it to me with the kazillion more cubes.
Not bad, but i want to do those times on 93 octane.
Kinda tricky to do being that I do not spray on 93 no matter what the combo is. I bought the motor complete, or else I would have spent more money on the cam and headwork and went 11:1, that way I could drive it easier on 93, but still use the good gas when at the track.
Nice looking car! I use to race a '79 Malibu 2 door and an '80 Wagon about 15 years ago. Bob

awesome. nice to see this thread. i have a 86 cutlass im building. im going to run the 383 for a while to get it going and get the car in better shape. then switch to the big block and maybe a decent size turbo. im starting to like the g bodies better than the f bodies.
That's a nice first time out!! A 325/50/15 Radial tire would take care of that rear end sway.
I'm saying that's a good 700hp N/A and 850 on the hose. You're well on your way to chopping that ET down.
What kind of rpm? shift/trap?
I did some calculators off the net and I am getting numbers of 800-825 at flywheel and 625+ to wheels with 3485 race weight on motor. Not sure how accurate that is.
Cross traps at 7200 on spray. Broke ring gear last time out and just stepped down to 3.90. We'll see how she does next week. Upped the jetting to a 300 hit. I want my 8.
Killer Ride, all this big block stuff popping up is making me want to ditch my Ls1 Build and pick up a 454 for an aluminum headed 496 with EFI. Like ZOne's sig, ill take the extra weight and the kazillion more cubes. 582 Low Deck anyone?

I ran a tall deck 496 in a 77 camaro with a build similar to yours, at 3700lbs w driver , 400 turbo,4.56s, and 295 65 15 mt drag radials,cal-tracs , it ran best of 9.86@136 mph, 1.37 60ft,at cecil co, using a computech , it showed 750hp fw. nice deal using that gm 427 truck block, lets you use a 6.535 rod in er! Now its got a 925 hp 565 in it,8.50 cage, sold out and tubbed and 4-linked it..........plans were to run the 8.50 index at cecil, now i just wanna get it together for next year
