anyone running a 408 with the TSP giant cam?

i plan to use my prc 5.3L stage 2.5 heads.

my questions are. what -cc valve relief should i go in the pistons?
and also. are you using stock length pushrods? (7.400)

havent ordered my rotating assembly yet. just want to make sure my ducks are in a row before i do.

i plan to rebuild the heads and use a 6.750 rated spring (that TSP offfers). and change the valves out with manley pro-flos.

I had Texas Speed install my 408 stroker with their texas giant cam and used their PRC 5.3 stage 2.5 heads. Anything about internals you would have to ask them directly I lost the install/receipt sheet. It has been over a year and a half ago and it is still running strong. I think I have a video of my car somewhere.......

The Wiseco -8cc dished pistons, GM MLS gaskets, and those heads will net you about 11.5:1 static compression which will still be pump gas friendly with that cam, and will help maximize the combo and keep low end and mid-range throttle response (torque) healthy!

Pushrod length will need to be measured after the rest of the long-block is assembled.

Let us know if we can help!
