New project I am going to run a GM Crate Engine in my Chevelle.
Its the Fastburn 385 which puts out 385 hp @ 5600 and 385 ft/lbs @ 4000.
So what converter do I need?

What trans? Id say something around 3000 to 3400.

Sorry its a 71 Chevelle (3500 lbs) with a Turbo 350, and a 12 bolt 4.10's.
I want some 1.5's 60 ft and try running tall 11's.
Asking alot I know.

3200-3400 would be sweet. You could bust a 1.5 just as long as you can keep a tire under it and an input shaft in it. All that and you can drive it to the track. May want to hit it with a 150 shot to secure an 11 for sure.

not to insult, but that is a tall order. especialy in a 3500# car. gonna need about 450-500 hp to get in the 11's. i do hope you can prove me wrong though.

I agree, I am running a 427 SB right now thats approx. 520 hp & 495 ft/lbs , with poor suspension and a B&M Holeshot 3000 converter with 4.10's.
Right now the car runs 11.60 - 11.70's @ 114-115, on average with a 1.65 60 ft.
I want to run a GM Crate Engine and see what I can do.

I replaced all the stock control arms with UMI Tubular and added an Anti-Roll Bar from HR Parts with Strange Drag Shocks.

Now I am thinking if I run a really good converter with everything else straightned up, I might squeeze something close.
