Hello my buddy has a 72 gs stock 350 100k going to rebuild MOTOR .030 over whats a good cam to run as a upgrade to a 72 smog cam nothing big thanks
What pistons you going to use? Before I ordered a cam, I’d check to find out where you’re going to end up compression wise. .030 pistons if they’re generic “rebuilder” pistons you MAY end up with LESS than 8 to 1 comp ratio as a lot sit pretty far “in the hole”
I have a Comp 268H in a dead stock 71 350 and it runs very well. Actually better than I expected it to. Used it because I had it, so there are better options if you are buying one for the application, but this would be a good option if others are not available. Thanks Brent
I rebuilt a 71 GS 350 engine over the last few years (it took that long to get machine work) and I decked the block, shaved the heads to get it to a true 9:1 compression ratio. The bore was standard at 91K miles and didn't need boring. I used a TA 212 cam and it is pretty sedate and runs on cheap 87 gas.
This is my wife driving my 71 4-speed shortly after we broke in the cam and got the exhaust buttoned up if that helps.
