Got the valves all set tonight. Rolled the motor to top dead center then adjusted 4 intake and 4 exhaust valves. Spun it over one time then did the remaining valves. My brother just had to refresh his memory on which order to do them in starting on cylinder 1. Didn’t have enough silicone handy to throw the intake on so I’ll pick some up along with some new valve cover gaskets before Monday. Now for my carburetor question. Carbs were phased out long before I was even born. I’ve got conflicting opinions going here. The current 650cfm Holley probably has around 500 miles on it but I bought a complete rebuild kit for it because of all the old gas sitting in it. I’ve had a number of people say the 650 won’t flow enough air higher in the rpm range to take full advantage of the new heads. One of my dads friends who has raced GM small blocks pretty intensely for years is going to come to the shop, rebuild the carb, and tune the whole thing for us. I talked to him on the phone before I bought the heads and he gave plenty of great advice. He had an 86 cutlass with a 260 cubic inch v8 and a 2 barrel years ago that he ran in the 12.00 class then built a rail dragster with a 388 cubic inch small block and a lot of nitrous. He swears up and down the 650 is just fine. He made a comment (can’t remember the exact numbers) that your average small block only needs 325cfm. When I researched my cam on the comp cams website they had a dyno graph for a 9.25:1 350 which is probably close to what I’m making for compression, a victor junior intake which is what I have, a out of the box set of iron Dart sportsman 2 heads, and they used a 750 cfm Holley carb where as I currently have the AFR’s and a 650. Peak power was made at 5800 rpm. Is it safe to say that my cam with my more modern aluminum cnc ported heads is still going to make peak power at 5800 rpm and my 650 will move enough air or can peak numbers and their rpm’s all change slightly due to the difference in parts? All though my car won’t make a large number of drag strip passes, I would rather squeeze every bit out of it while it is there. Or am I just way over thinking this for not a big difference in power?
