With his IVC and compression. Gives him a DCR of right around 8:1. Could there be more? Absolutely. Is it worth it? Ehhhh. I don't think so. What's half a point of DCR worth? 5 horse? And with the headaches of good gas, detonation, pinging, etc etc that comes with max DCR on iron heads. Gotta remember, factory 340 cars had a lot better gas around to run on. He's at sea level, with cali 91 octane, not a recipe for high compression unfourtunately. Given that the builder was aiming for 8:1 DCR, and landed right near it. I think it's a good setup.
I never said I was the only one that could put things together. I said I figured it out when you couldn't or wouldn't. You just made the broad statement that "His DCR is too low, he should be at 8:1 to 8.5:1. Which he is at. I'm a details man. Rather than say "You did this wrong". How about you try and figure out if he actually did it wrong first. That's my point.
I'm not derailing anything. I'm giving him actual and intelligent advice. Rather than saying "No you did this wrong". I'm saying "Well this is what you got here, and this is what you got here". See the difference? One is just telling someone they did something wrong. The other is teaching someone. You were already asked to leave this thread by OP. If anyone is derailing anything, it's you.
Oh good, exact cam specs. Now we should be able to tell you exactly what you got. Using
Wallace Racing - Cam Degree Calculator. Your IVC is 61.5
I'm curious how you came to 9.7:1 compression? Punching everything in you came up with on
Compression Ratio Calculator - Wallace Racing gives me 10.67:1.
As for carb. If you got a 750 double pumper around. Give that a shot on there. You might be pleasantly surprised.
