fattest cam in a 340?

I don't know if you're being serious or not...

You say you can't time it with a light, and that the cam was installed incorrectly? How do you know it was installed incorrectly? have you degreed it? And how is it you can't time it with a light? If you can't ascertain the timing with a light, then you might have it on the wrong plug wire or it might be severely retarded.

Back on the cam, even if you don't know the specs on the cam, if you degree it, you'll know...and it may be a good cam--you won't know until you put a wheel on it though...just food for thought...also, a degree kit costs less than a new cam.


You're actually leaving out a few details...

Let's assume for just a moment that all's well with your engine; good compression, free flowing exhaust, matched induction, stall, gears, etc...a good cam for lope with such low static compression ratio from a 73 340 likely will make for a soggy bottom end. The hughes whiplash cams and the Comp thumprs are supposed to give a lopey idle and decent performance, but I can't speak with any real familiarity.
