how about a turbo ford sohc 2.3 block (turbo capri and turbo gt mustang and svo mustang) with the volvo dohc head swap. you get the better block and a better head. the na guys of stangnet who have done this make the same power as the stock 2.3 turbo motor from ford. doing the head swap adds 100hp na. on a turbo block running stock boost but with a custome tune, just the head added close to 200hp. bassicaly its not that hard to do.just run a one extanal oil line and have a little block welded to the head.
