Ported & Polished Heads = Pulley Drop?

Bedwards

If I installed some L26 ported and polished heads on my 2001 GT with the SS M90 kit, what kind of pulley drop could I expect? I'll probably do a cam at the same time, but I'd like to know what I could get away with (without the cam).
 


You already have headers...

Heads/Cam probably/most of the time allow at least a half inch drop in pulley size. Since your high compression a 3.25" or a 3.4" might suffice with more timing...should run great.
 
ZZP doesnt sell 3.25 pulleys anymore with the SS Kit. Your gonna need to go to a GTP belt/pulley set up to run under a 3.4
 
I was just curious. I am probably going to sell my heads and just buy a VS cam. I can't afford to get my heads cleaned up and built at a machine shop.
 


People have made power with the VS cam. It's very streetable and I don't have to change any valvetrain components to run it, correct? Plus I can get a VS cam for $230 shipped.
 
If I wanted to change the springs, I have some new G8 springs I could use. Is that all I would need to change to use an XP or S1X cam?
 




G8 springs and retainers would be fine on a VS cam and I'd definitely change them if it were my car.

The VS is still a very noticeable difference over stock.
