hi guys, sorry im late

Yes mike I do have vortecs on my 383. I have had problems pinging in the past, but my intial timing was way to advanced when that was happening. I have stock flat top pistons with 4 valve reliefe so 10:1 is the compression. 92 octane is all it let it use and it runs fine.

I suggest a MSD Super HEI kit myself. No need for a new distributer. I got tired of the chip in my ACCEL HEI distributer giving me problems so I bought the MSD kit. Awsome product. Comes with either 6a or 6al box, a blaster 2 coil, new cap and all the wiring and instuctions [the instructions are great, really easy install] Its like $150 or a little higher for the 6a box package, $250 or sumthing for the 6al package.

As for the carb, I was running a 600cfm cater AFB on my 383 when it still had the stock 76cc heads, no problems. I also had it on for about 3 weeks after the head swap with no problems. I then was running a demon 650cfm double pump, mechanical secondaries carb, and that woke things up a lot. That was stolen 2 weeks ago so I am now going to get a demon 750cfm double pumper. I suggest you get AT LEAST a holley or if you can afford it a demon 650 double pump. Get the 750cfm if possable.

P.S.- mike, in some forums for some reason I have my id as tom ,not bored&stroked, wierd eh?
