i have had this Saleen for years.. last year i built a 408 boost ready, with a bullet solid roller , AFR 220 heads super victor all ready for boost even went as far as to put Big stuff 3 and a digital programable 7 in it.. now I'm ready to do the turbo and I'm thinking i should put my Dart 440 ci in there with my AFR 225s to handle the 88 MM t6 turbo, i have also pulled the 6 speed out and went with a power glide. what is everyone's thoughts. is this too far, should I leave the 408 in it and boost that.. or pull the trigger on the 440? i have everything already.
