Hello,
I am rebuilding my engine again and would like some suggestions on what pistons to get or if I should kept the stock ones. I do have a budget, so nothing too expensive.
Its a supercharged 305 TPI. Also any suggestions for a manifold?

I don't know what to tell you about intakes. However, on a budget I would look at a set of flat top hypereutectic pistons. They're in between stock and forged. A great piston for an engine on a budget.

for supercharged aplications make sure you get pistons that will keep the compression reasonably low, shouldn't be more than 9:1 in my opinion

I agree about the compression ratio. Keep it low if it is a supercharged motor. What kind of supercharger are you running? How much boost?

 

For supercharged or NOX applications, forged are really the way to go. The hypereutectic are cast using a different alloy than what is used for what is normally called "cast" pistons, but are actually not as good for power adders as stock cast.

Forged are by far the best for your application. Cost should not be the basis for your decision.
