Trying to make my mind up between the two, looking for the one that pulls the hardest down low for the street, but still be a good track cam. Looking for plenty of comments. Thanx guys

Look up the tq numbers on f13's , they all make good tq and not just hp. That will give you better avg numbers and that is what makes cars fast.


I just added Edelbrock longtubes and with my currrent setup, I made370 ft lbs at 2800 rpms , went up to 409.33 at 4700 and was still making 350 @ 6300rpms. Hp was over 400 from 5100 all the way to 6900 with a peak of 425 at 6300.

My cam is a f13 +4 on a 112lsa my heads are so mild its sick. my heads only flow 256@.500 -257@.600 and the exhaust is nice but with stock valve flow 219@.600 with no pipe. and traps 120 mph in street trim with 17 inch forgelines all the way around.

f13 gets my vote
