PI swap for my 96 gt.

[smokedya2]

I bought heads from 04 w/o cams. My plan is to get them port polish and milled what type of cam should I put in it for everyday drive. I already have PI intake and a super charger from procharger and tuned w/ 373s. I basically want the best power/torque w/o changing anything on the bottom end. I was looking at comp cams or trick flow cams.

Oh forgot added a upper intake from trick flow and a 75mm throttle body as well.

COMP CAMS XE270AH are what I want to get down the road when I do cams.


Either that or a set of OPS1 cams from Ortiz Performance

Your swapping out the stock npi heads for pi heads; am I correct? You do know the heads are pretty much equal when under boost.....And by going with the higher compression pi head your compression ratio will increase. If you haven't done the pi intake and cam swap on your stock npi heads yet, hold off on the head swap. Swapping the '04 heads have more against you than the npi heads would. Swapping on the pi heads to your stock short block means higher compression, less cam duration than npi, 4sparkplug threads (notorious plug blowouts) and money spent on gaskets.

If you where going n/a on the cheap I'd say have at the pi head swap.

boost and moderate compression is awesome...

I had comp 270 in my old set up and power was good, those with ported heads and a low boost addition will be fun, fyi I have a rare frpp tb for sale

I know ratio changes to 10.1 on the pi to npi. I just want a good cam that sounds great and the comp cams xtream is on the top of my list. Thanks for yall input

make sure those cams dont have a huge lift...NPI pistons have a shallower dish and can have PTV issues.

True but if you degree your cams (as everyone should anyways) with no followers in (as i have explained several times) the cylinder heads, you will limit your chances. Also Lift is important but as is duration....

rather then buy an off the shelf comp cam, get a hold of Nick at MHS www.modularheadshop.com for some blower friendly cams.

CMS stage 2 blower is what I have and another great choice.

Nick sold the MHS company to another business.

Oh wow I hope he made some money.

Ok get the cms cams.

You can still buy cms cams I been looking into them as well but if they are made by the same company idk.

CMS is the former VT and a very good set of cams. I can't think of many complaints at all with their cams over the years. Scott was always a good person to do business with, I even bought my pistons/rods from them.
