has anyone ever dealt with the trick flow cam kits for our 2v? looking at the stange 2..

mrtstang

Those will not fit the stock PI head just so you know. You'll be much better off with something different.

^^^ Why won't they fit?

mrtstang

PVT contact will occur. Specs are to aggressive for the stock pi heads

nateCR

what has to be done to make them work? most of the aftermarket cams like the cms require ptv clearence checking

mrtstang

Machine or replace the intake valves and/or notch the pistons is one way. Another is to retard the cams to get more ptv clearence. Only problem is that by retarding the cams you'll loose some good mid range power.

Honestly (if you're staying with the stock heads) you're much better off with different cams. The amount of time, effort, and money that it would take to make these cams work and fit correctly, would not be worth it imo. Now if you plan on going with some different heads...well that's a different story then.

so whats the max lift we can run on a stock set up other then springs
?

nateCR

has anyone used the stage 2 comp cams? whats the max lift for our stock pi valve springs?

mrtstang

With stock springs you really don't want to go more than a 550 lift. Even that's pushing it. 550 exhaust/500 intake will work well with stock springs if you don't over rev it.

In fact, even with good springs, there isn't much of a benefit to go over a 550 lift on the stock heads.
