Just a 284-484?

I'm sorry but 460 hp from that 484 purple cam is a load of crap ...that is a 350 hp camshaft in the real world.
On a real dyno a normal 340 with a set of ported X heads/headers/intake/750 and with the sun and moon and stars all aligned on the best day 375 hp.
I've read a lot of stuff on this board that makes my eyes roll but from my personal experience on a real dyno it's just not going to happen.A 484 purple cam that makes 1.35 hp per ci in...not in the real world...This one I just had to chime in on.
Believe what you will...that 484 cam will always be a 49.95 cam with lifters in my book.

Couldnt agree more. I just can't see it. I think way too much faith is put in the simulation programs. If someone has quick ETs with this cam, please post the mph and vehicle weights and the rest of the package. One can run mid 12s with 375hp in a drag race oriented car. The few street cars I'm familiar enough with to know that cam was in them never produced mph or ETs that said that cam was generating that kind of power and I never seen one make over 400hp on a dyno. You're talking a cam that has .460 lift at the valve, and is only open for a short time at that lift because the lobe is pointy. The heads would have to flow 220cfm or better at around .250 lift to move enough air to make 400hp in a street engine package with that cam.
