I’ve not figured anything out yet. Kind of working backwards from what I have. Measured spring height and it’s at 1.670 so I’m figuring about .550 lift to be my limit.
Any suggestions, GT?
Thanks

I wouldn't be too concerned about cam profiles. When my hemi was broken for 1 1/2 seasons I ran a 6-71 blown alcohol 400 (-16 heads) with an ancient Crane hydraulic cam (from 1958) with good success. I would guess about 800 HP, based on comparison to dyno numbers of my competitors.

im kinda following along on any blown pontiac threads i see, do you think the 800hp mark is pretty easy to do with a 400 or 406? and a blower.
