Best guess on 416 motor

it should go high 10s

mine went 10.79 @ 128 mp/h

the engine is as follow

360 1973 block .040 over
scat rotating 4.0 stroke
h beam
flat top that give me 10.57 cr,
cam is .630 crane roller 272*int and 282*ex
108 center was at 106*
w2 race heads fully ported
1.6 harland sharp rocker
m1 crappy intake
750 cfm carbs with alote of work on it and give 835 cfm
1 7/8 tti headers

the car went 10.79 like said earlier in full trim with 28'' tire
4200 stall dynamic converter

ps. I did retard my cam a little last spring at 102 I lost alote on the mp/h
and gain a little on the 60 foot with the same et.

so it will go back to 106* so I will regain my mp/h

i did it at miramichi dragway new-brunswick

You need more compression with that cam,stall and carb.
What does the car weight at race weight?
What did the W2 heads flow?
