Guess you can't believe advertised HP?
I thought the street heat was more for bottom end than the others as they claim Idle to 5500 as opposed to all the other @1500 and up......I want all bottom end as there are no tracks on Long island anymore should I just stay stock????
When you read these articals in magazines, you have to see what they are testing it on. What works best for a blown stroker might not work so well for a stock engine, or vise versa.
You have an intake that is set up for a 1500-6500rpm, a cam set up for 2500-7000rpm, and heads that are set up for idle-4500rpm. What do you get: A motor that dosn't run worth crap and makes no real power.
I think on stock or ported heads or even cast GT40s I would do a edelbrock performer , not the rpm .... or even a tmoss lower ..... if you go with a better head/ cam then get the rpm or typhoon or trickflow , systemax etc...
