it's .030 over L69 (H.O.!!!!!) with a mild crane cam (not sure of specs right now) with a performer rpm intake, 1.6 roller tips, ~9-9.5:1 compression. edelbrock site says the 1403 (500 cfm, electric, non-egr) is for 305 and smaller....i had the 1406 (600 cfm, electric, non-egr) and it was ok...maybe too big? i dont' know what kind of vacuum it was pulling, but it was average. all my stuff worked...
and since i'm on the the mic, i installed my motor already...without the distributor...do i ahve to take it out to install the distributor...i think i made an uh-oh....
and another question..since i am using the 1.6 roller tip rockers, do i have to use longer lenght pushrods or is std. ok? the valves are the same (stock from L69..what is that? 1.84/1.5) thanks guys...joey.
