What recommendations are you looking to get? What heads, Bs or Cs? n/a or FI? What compression?

The 4.75s are only about 8ci larger than stock so don't expect any increase in power unless the compression ratio is higher (than stock).

My plan is to go thru with this 4v swap and then in the future put on a turbo.
I already have the shortblock on order.the other stuff like heads and etc i have .

You said you were going with stock compression ratio of 9.5:1 and never said anything about 03/04 cobra engines.

All 93-04 naturally aspirated engines had 9.85-10 to 1 compression while the 03/04 Cobras had 8.5:1.

If you buying an engine from MMR jsut tell them the compression ratio you want.
