THought I'd share this Dyno from my 355 completed and ready to go in. THis was on Race gas with a carb. , now the true test, The TBI and the seat of the pants Dyno.
She made 375 - 451 Tq. , very consistent on all 5 pulls adjusting timing in between. I think we had one run at 377, made power at a different RPM on that run.
Lots of Smoke down low which is what I wanted. little 260HR cam and allot of work...

I seldom see dyno results from my tuning. I had one of my tuned 350 TBI motor make 330 RWHP, with a similar cam, 454 throttle body / 80 Lb. injectors using a 16197427 PCM. Maybe 330 RWHP is equivalent to 375 Flywheel HP taking into account drive train loss?

I think that is a more realistic figure.
Remember , we were on 105 race gas ( because that's what was in the tank), no accessories, electric water pump, long tubes and a well tuned holley 650, on the flipside we did run a little fat and with some more time I think we could of got a few more ponies.
IT wasn't really necessary to DYNO it but we like to do it... it's nice to run em to see if anything is wrong, etc.. I like the seat of the pants dyno myself...
