Need some help on selecting a camshaft for a interesting build.
It's an oddball stroker engine that will be a spare for my airboat.
The boat-15x8 Air Ranger , 2.88 Stinger gear drive, 78"WW Super Wide 3 blade that needs to turn 2150-2200.
The engine regularly sees 6000-6200 RPM all day long. The boat and the set up is not changing so what camshaft would you use in a 383 stroker with these specs?

1969 307 2 bolt main block- casting #3956632
1970-1980 400 SBC crank- casting #3951529
4.0 over bored pistons yes fo' real.
Heads- 1.5 intakes ,2.02 exhaust 75cc chambers casting# 3973487 X
Rods-5.7 3.75 stroke.


Yeah I know its a odd build but its what I have and all freshly machined and ready for assembly minus a cam and lifter set.

I'm thinking a Hydraulic flat tappet (non roller) since I'll reuse the steel rockers , etc...but what size, lift dur,etc?

Thanks,
Bob
 
It doesnt matter what cam you run, it's not goin to run worth a sh*t with the 1.5 valve in the intake hole and the 2.02 valve in the exhaust hole :lol:

Why not that's a stock head/valve design, I'm not looking at a drag engine here just a good runner.
 
I was just funnin with ya bud. I think you meant 2.02 intake valves and 1.5 exhaust valves. You have it backwards on your original post. Again, just messin, good luck on the cam :thumbleft:
