1/4 mile estimate
 

around 425 horse motor
3000 stall and 3.73s
in a 83 longbed truck

12.30's

13.50 @90

Mid 13's at best :!: :!:

I agree, thats alot of weight to move. High thirteens at a shade over 90 mph would be my guess...

Estimate
 

13.70's @88 mph.

You will never know until you take it to the track :!: Talk is cheap, but the time slip never lies :D Where did you get 425 HP from, maybe 275 :!:

Be nice. 425hp does seem high for your application. I agree, Penwell is racing the 23rd. Once you make a pass you can tell your true HP. No ifs,ands,or,butts..........My quess would be a 14.98 at 86mph.

I was trying to give the benefit of the doubt. Keep us posted on what it runs. Be like PassTime on speedtv.

im gonna run it
and i got 425 from the fact that i just got a new manifold carb and heads
maybe overestimated idk
but wel see when i go to the track on the 23rd i guess :wink:
