I've searched around in the archives and didn't really find what I was looking for.

I have some mildly ported GT-40's (exhaust side, mostly) and an Explorer upper and lower. I'll be using the stock TB and prolly a Cobra MAF and 24's. Typical unequal shorties and cat-less h-pipe with the current FM cat-back exhaust will be added when the heads are installed.

My question is this: Should I use 1.7 rockers on the stock cam or switch to a different cam ("E", Steeda 19, etc) and stay with 1.6's? Either way, I'll be buying new rockers. My goal is not "max hp" just a few nice mods to help me feel the "pull" of a respectable/somewhat powerful car.

Thanks in advance :SNSign: !

I'm talking about using the stock GT cam with the 1.7's. Or buying an aftermarket cam and using 1.6's.

I'm trying to discern whether the aftermarket cams are that much "bigger" than on OE cam. Also, whether I will need to tune it, with 1.7's and the OE cam.
