My Freshly built 514 went to the dyno today to some very dissapointing numbers. With that said I need some help - I didn't expect my engine's first pass to end up with 422hp. Don't remember the tq off the top of my head, it was less than the hp. I haven't seen the printout so I don't even know how many rpms it pulled.
Here are some specs -
514 rotating assembly bored .80 over with Flat top forged pistons. Dove C heads. Tunnel Ram with dual 650 carbs. Cam is a Comp 34-343-4. Gross Valve lift - .640 intake and .640 exhaust. Duration @ .050 is .262 intake and exhaust. 3 angle valve job has been completed on the heads but I do not have flow numbers.
Any ideas on what can be holding me back? To much Cam, not enough flow? My mechanic said there is some corrosion on the carbs but the engine was not running lean during the initial pull. He is going to rebuild the carbs and go again.
