ideas for top end package

[bojvette]

My friend has a 1972 corvette base motor thats .30 over >> he thinks it has lt1 heads ** automatic trans.
I have a lt1 but its now a 383 and i have looked in every book on 1972 corvettes and to figure out what he has
now*** will be street used
he wants a top end **aluminum heads maybe 70cc ** roller cam **maybe what ever carb thinking 600 to 650
edelbrock has a full kit everthing to bolt on and start [ gaskets** head bolts ]
now hes called edelbrock thy told him to get a none roler / and onle 65cc heads?if he went higher would need a taller coverter [ i can't find out what base one is ] any ideas or help let me know

thanks jim

That should be pretty easy- Brodix and Dart but have top end kits- no cam from them, but that should be pretty easy too. Maybe Trick Flow has a complete SBC kit.

I think factory was around a 1700-1900 stall. The heads are the same casting number as lt1's and the only difference is the base was a 1.94/1.5 vs the lt1 2.02/1.60. They should be a 487(x) casting. Look at Lunati's roller cam setups as they have some nice ones.

And a 600 to 650 CFM carb will be great at low RPM but he's not going to see much over about 5500 RPM. It'll fall down around there when it runs out of air. A 750 would be kind of a split between low end manners and top end screaming. I've tried that combination on a 350. 650 was great down low, but no top end. 850 was worthless down low, but pulled hard until it ran out of valve springs (floated valves). Settled on the 750.

Dont discount the Q-jet or even the edlebrock .. both do very well.
