Post a pic of the dyno curve and tune. What's your timing set at? Af ratio? The cam is fine with 1.6 rockers.

Actually even a bigger step backwards.

old cam 244@ .050 int/ex .501 lift,,106ICL 110 lsa
new cam 214/224 @.050" .444/.466 lift,,112 LSA

OP, F' bird gave you some good advice there with the cam, head swap, header size and explained clearly the reasons for them all. You went out got the wrong cam, wrong cc heads and wrong headers???

Your DCR is going to be up even more now that little cam, limiting the amount of boost ya can utilise with pump gas???

Why you ask advice , get advice from one of the sharpest tuners on the forum, and then ???. ..

Off the bat unless you're running really high boost your timing is probably a hair too low, but you'll probably need better fuel if you put it where it should be.

Jets seem really big to me but I may be wrong, it's been a while since I messed with a Holley.

64cc isn't a bad choice if you plan on running race fuel or ethanol. Maybe you are?

The cam isn't small for street power, it'll definitely limit your peak but with good heads headers and a blower 500hp should still be attainable.

If you're running ethanol I think you may have a pretty strong street runner. Are you running ethanol? If not I'd switch to it.

I am just waiting for my dyno graph should have it by tonight or early tomorrow. I have been checking on some things on the truck and just now noticed how close my air cleaner lid is to the top of my carb. There is only about 1/8 inch of clearance could this be causing a major problem?
