Engine combination RPM range?

I have Dart Iron Eagle 215cc/64cc cylinder heads. Clevite 246/246 @ .050, .510/.510 INT/EXT solid lifter camshaft. (lift numbers with new lifters installed) I was wondering what my operating RPM range would be with this combination seeing as I haven't driven the car yet.

Thanks.

Zach

Looks suspiciously like the old LT1 cam with 1.6 rockers?

If this is a 350, probably 3000-6500. Peak HP in the high 5000s to about 6000, peak torque in the mid-high 4000s.

There's ALOT better cams available today than that 40-yr-old one.

I'd guess 6000-6500 rpm. Depends on what valve springs you have though.
