My local track is at 550 ft. above sea level. I don't know what the typical DA is.


What's your prediction for 1/4 e.t. and mph?

What's the car weigh?

I've yet to weigh it, but it is a full weight iroc.

High 11's with traction.

Thanks for the response. The car hooked well going low 12's with the old carbed 383. Hoping for 11's!!!

Just an update on my setup,

picked up a fast 90/nw 92 combo. I'm hoping to be solidly in the 11's. Also added #36 injectors.

Thoughts anyone?

Lighten it up some, mickey pro's or hoosiers and restall that yank 3600 to 4000 and shoot for 10's

I can run as fast as 11.50 at my local track before needing cage work. I'm not installing a cage. Not really sure what I could do for weight. The car is nearly mint so I'm reluctant to do much to the body or interior. Any thoughts on what it might run with current set up listed?

I'd expect it to go somewhere around 11.50's if it hooks

wph351

iTrader: (3)

That would suit me just fine thanks for sharing your thoughts. Anyone else?

I updated post #1 to show the parts that actually ended up in the build. Going to Frost next week for a dyno tune session. Any predictions on hp/tq numbers and 1/4 mile e.t. and mph? Anything over 400 rwhp and any e.t. in the 11's and I'll be tickled.

380 rwhp and 11.7

380 will be disappointing but understandable with the small cam. 11.7 would be great. Thanks for sharing your thoughts.

410/385 and 11.30 if it hooks. I'd bet a 1.50 60"

Had it to the dyno yesterday. On the mail order tune it made 390/365. Only was able to make one pull as a broken tailshaft housing ended the session.

You have room to grow then!

Yep there is some on the table yet. He was able to get enough data to flash in one update. I'll drive it as is for now. Going to the track in early june. An 11.anything will be a success in my opinion.

11.30? That's way quicker than I was thinking. But that would be awesome man!

All depends on traction. That car should weigh a lot less than a 4th gen. Especially with the LS1 in it. That's a 100 pound savings over a SBC motor instantly, my 92' formula tipped the scale at 3300ish from the man so the motor swap alone has it at 3200 race weight. 3600 stall and motor mods FTW IMO. Where you running at? Dinwiddie or Richmond?
