Re: mild 350 dyno results
My .060 350 with trick flow 195cc 62cc heads, 228/234 @ .050 with .484/.490 lift @ .050 cam, performer rpm manifold, 650dp, 1.5 roller rockers made 311 rwhp and 346 lb ft of torque. I run 36 degrees of timing. I was also lean in the secondaries on the dyno. I have factory style dished pistons .030 down in the hole so my compression is a little low for my combo. I have 1 5/8 headers into a 2 1/2 inch flow master exhaust, a 4spd and posi rear also. I would say your right where you should be. I would rejet the carb and go back and play around with timing Maybe you can pick up a couple hp.
My brother has a 72 nova with a slightly bigger roller cam than me, rhs 180cc heads, 670 vac secondary carb with a 200r4 trans and made almost exactly what you did.
Right after I dyno, I tried to figure out crank hp. Without actually putting the engine on an engine dyno it's all just a guess. I found articles where the factory big block copo 4spd cars made less rwhp than I did, but according to the industry avg of around 15 percent loss for a 4spd, I'm only making around 370 crank hp. I was driving myself crazy, but then I just decided to have fun with what I have. I'll save up for a bigger engine later.
