Anyone want to give me a little info on what a port & polish is/ what it does? and about how much would this cost, thanks

P&P is done to the heads to improve air flow into the cylinders. Combined with a good set of cams, 35 hp gains are possible. The ports on the heads are made larger (matching the holes in the gasket usually) and then smoothed (polished). It's good to have the intake done to match, but with the plastic, I've never heard of anyone doing it.

You can buy p&p'd head from patriot or vt engines with or without cams.

You could get the bullitt intake manifold to port match, but it's pretty expensive.

I just saw where power + plus products has released a new aluminum intake for the 4.6 PI. You could possibly port it to match I guess.

very, very expensive bro. the labor ALONE just to pull the heads off is near $900

Hyper00

Well you could probably pull the heads yourself. That would cut the total cost in 1/2. Or you could buy some cheap used heads and have those cleaned and P&P so you can minimize your downtime.

If you have a 96GT and only trying to get a max of 315 HP and will get a blower from 6 to 8 psi, is P&P the way to go with maybe blower cams?

Because I am hearing that putting in PI cams and intake before you get a blower will make the compression to high and cause problems

Suggestions?

I have heard cams alone will gain about 20-25 rwhp. So If I got my cylinder heas ported and polished. I am only going to expect like 10hp?

The cams and intake dont up the C/R, the heads do. i have seen quite a few 4.6 pop a piston at 10 PSI. so i would not go any higher then 8psi on stock rods/pistons. the easy way would do get PI heads and N20 then you will be at 315 easy.

cams alone will net you a good gain. a p&p is one of those mods that help other mods. i.e. a p&p will allow air to flow more/better therefore a s/c or a cam installed after this will net higher hp numbers than with the cam by itself and p&p by itself
