Jr. Day eh?
mmm...well it depends a lot on how much you wanna spend. I rapped some #'* into the Dyno2003 sim software and came up with:
'63 cam, ported heads, rockers, 10.1:1 CR, smaltube headers and muffler:
Same but 8.5:1 CR, no headers:
Not sure of its accuracy but I got renewed confidence yesterday when Horsepower Tv used the exact same program while they were building an engine and it came up within like 3hp of actual dyno results. Of course it is their job to sell the stuff though. In anycase I wouldn't live by it, but it should get you in the ballpark.
