    So with the pushrod 302 a cam swap will gain next to nothing with stock heads, maybe 5-10 hp at the wheels. What kind of gains are yall getting after a swap? What's the stock lift and what is the lift of the popular cams used with stock bottom ends?
    Just curious.

    What year?

    96-98 NPI with stock Intake you might gain 15-20hp because the Intake is a POS.

    99-04 PI you will gain 25-30hp on a stock engine.

    He mentioned a stock 302. Idk if most go to the work of swapping a cam, and then leave the junk E7's bolted on. Cant find a set of GT40/40P's?

    But this is the 2v section

    I will start off by saying the question is too general.

    caveat don't expect LS numbers from a modular cam swap. With a 4.6 lift can quickly run you into PTV issues.....

    In my personal opinion cams are mostly cosmetic when not a part of a specified combo. Its totally fine to pick a cam soley on how it sounds.... its better to have a great combo H/C/I/FI though. There is so much to this topic...

    Oh, sorry, my bad. I usually just click on threads that are "unread". The wording is not great, and definitely vague.

    Yall answered it well enough. I understand combos etc. I was just curious because it seems like there are quite a few modular guys doing cam swaps w out swapping heads.
    *edit* no not too many pushrod guys are swapping cams unless they do the whole topend. H/c/i
