383 build no power
as told compression was 9.7 by original owner
OOps, I screwed up! I had it in my head that post #1 stated 10.7. Sorry about that. And that then explains the problem.
As previously stated, too much cam for 9.7Scr, and the low-stall TC. The cylinder pressure is just not there at the 2000 stall-speed.
Stated another way tho; not enough stall for that 284 cam.
So to recap; you have two choices. A cam with an earlier closing intake, or a higher stall TC. Easy-peasy solution. And either solution is close to the same money.
A 3500TC will turn that 383 into a hi-rpm screamer;perfect for that short-stroke,big-bore engine.With this TC you can put some more serious rubber in those wells.
And a 262/110 cam,in at 107,( or that Lunati 256/262/112 in at 110) will turn it into a tire-frying,smile-inducing,tow-anything,torquer.This will get you a 58*ICA, and might bring the Dcr up to about 8.1 and the cylinder pressure to over 160psi. But I think the TC would still need to be bumped, just not to 3500.Probably 2800 would do it.Maybe even a tad less.This would make a nice cruiser engine.
Since the TC has to go in either case, Hmmmmm;decision,decisions........Lots of good advice in this thread; I counted at least 8 right-on posts,not including my junk.
