318 running and sounding way better.
Johnny mopar.........
It's a stock 30 over 1967 318 with a .225 @ 50 cam with .453 lift ground on a 108 LSA.
The 1967 920 cylinder heads are a closed chamber design adding to the compression.
It's a little over 9.2 to 1 compression.
Edelbrock performer intake with a 1/2 inch open spacer under a 750 proform carb.
Dynamic 10 inch 3000rpm stall converter.
3.91 7 1/4 rear.
17676 cheetah valve body in a 904 torqueflight transmission.
I can really hear the engine now and listen to how it runs.
I always keep tuning my engines and it helps to hear the way they run when working on them.
I would rather have it a little to loud then to quiet.
What kind of car or cars do you have?????
