I Need Help With A Math Problem

[Adger Smith]

Casey I didn't bother checking, but I'm pretty sure there was a difference in the intake lobes on the cam between '69 Z-302 and '70 Z-350. I think it was around .030 less on the 350.
Might be a little harder to feed those few extra Cu in.
Still soft...IMHO

The now away cams, the .050 doesnt make a difference, if it was when we measured duration it might, but there's no substitute for cubic inches. If you use the same ratio of factory hp to the nhra rated, the 360 hp should be nhra 383 hp. The ratio is 1.06 on my advertised 290 hp to get to 309 nhra factored.
