blew motor, got it bored, heads ported and stroked to 383c.i. nothing else has changed. next to the computer needing tuning what else should i do? fuel system, injectors? exhaust? is the stock SLP exhaust ok? i like the look of the twin tail tipps on the driver side.

I swapped out my 2OTL when I did my 396 because the guy that did my dyno tuning said it was costing me 15-20hp. I decided to go with a 4" Mufflex catback w/Spintech race muffler and don't regret it one bit.

I'd go with a 52MM TB, long tubes depending on emissions restrictions. Are you getting it dyno tuned? If so, whoever does it should be able to tell you if your injectors are flowing enough or not.

What cam are you running?
