Questions about future mods I would like to build a forged block topped with my LE2 heads, and procharge it. So here are my questions:
1) I would like to go FI with a D1SC, on my heads what is the largest displacement I should consider. Right now I'm thinking 355.
2) I will be replacing my rockers in the very near future, I want to go with 1.6 nsa on a 7/16 stud.
a) Can the new larger studs be swapped right in, or must I remove the heads and drill and tap the holes?
b) What do I need to know, or do, to go with nsa rockers?
Thanks all -Chris

displacement doesn't dictate compression so if you want to stick with your heads, I am assumung they are somewhere in between 52cc and 56cc, but you need to know exactly how large they are so you can buy dished pistons to get the compression ratio you want. Any displacement will work for FI as long as it is built for it.

Dude... your not understanding me. I am not asking anything about the compresion ratio. I will figure that out on my own once I decide on a CUBIC INCH DISPLACEMENT for the FI block, which is what I am asking for help with. I dont want to buy new heads, and there is no point in paying for the machine work and bigger crank to make a 408 if my heads cant flow enough to support the larger cubes.
So with all of this clarification, does anyone have any input?

You will need new hardened 7.20" pushrods and hardened guideplates as well.

studs will swap right in, as far as the heads go, they should be good for whatever displacement you wanna go with. one thing though, if you plan on going with a procharged stroker, you might want to consider going with the le3 heads instead, or porting the le2's out a bit more for better flow. not entirely necessary but it would be a noticeable gain
