[Sonic Mustang]

Well I am looking for more power from ole Sonic. I have been investigating both spray (NOS) and SC. As I understand it if I go with SC I will have to rebuild the engine with forged pistons that are scalloped on the top to lower the compression ratio which stock is too high from what I have been reading. No need to do the rods as they are already forged but they do recommend shot peaning them and the crank.....sigh....man this is getting expensive. So I thought I may just add a 75 hp shot of NOS instead. Anyone else doing the same? Looking for feed back.
