Just what the title says. Keeping stock springs and stock heads trying to decide on which to go with.

CMS Stage I vs MHS Stage II cams

I've compared both those cams as well, and have decided on the MHS stage 2's. Reason being is that you can actually over scavenge the exhaust ports by having to much of it on the PI heads, and as a result, not make as much power as you otherwise could. With that said i think the MHS stage 2's should make a little better power (due to being more intake vs exhaust biased) than the CMS stage 1's even though the specs are very similar.

Here's a clip of a guy who has the MHS stage 2's.

^^^^^ ya thats my car haha. i saw about 40 rwhp after tune with mhs stage 2 cams. can't complane with those numbers for a mild cam. main reason i went with them is because they worked with stock springs and nicks vast knowledge or the modular engine. great guy very personable and great product=win for me.

mrtstang

The cams run $580 i believe.

I forgot that's your ride massred98gt lol. It does sound good.

SpoonyGT

massred, are your cams the PI stage 2's or the NPI stage 2's???

mrtstang

IIRC, he has the PI stage 2's.

Ok, cus i was going to say that the NPI cams have different exhaust side specs than the PI's do. So they might not sound exactly the same. Im liking the stage 3's from MPH if i can get my stock valves ground down or find some SS valves for cheap. And i can do it on a weekend at my buddy's shop and he can install them at advertised specs then and i wont have to worry about PTV clearance with the ground down/new valves...right?
