I am in the process of building a 355 for my TA.

So far I have the Forged Rebuild kit from Summit, going to get Eagle SIR 5140 forged rods, got a comp 224/230 cam, ported heads, ported intake, ARP main stud kit, stock crank, longtube headers, 2800 stall, and built trans.

My question is has anyone got one of the TPIS oil pans for LT1s? If so how do u like it?

My other question is I am planning on running a STS turbo kit on this motor so I am going ot need to low hte DR a little from what it is now, so I am going to run felpro 1074 head gaskets to get alittle more chamber size and I am going to have the chambers on the heads opened up to say 64cc from the stock 54cc. How much boost will I be able to run?

Anything else u see that I need.

I would like ot make aound 400-415hp NA then around 500 on boost.
