Well I finally finished the tear down! The pistons were very hard to get out, I will be suprised if .030 will be all I have to bore the block.

Tech, I agree with your flow assumption on the edlebrock intake and 624 heads. I took out the caliper and did some measuring and you advised, the ports on the performer intake are only slighty larger then the head ports, I should be able to clean the ports on the head up with a die grinder and get the flow profile I need.

I believe, with all of yall's help and my limited budget that I have come up with what I am going to build:

010 block bored .030 over (the block is on its way to the machine shop now)

Stock 624 heads with 1.72/1.5 valves, some porting to match intake

stock exhaust manifolds with 2.5 pipes into one muffler with dual outlets behind the rear wheel, no cats

northern master rebuild kit with comp cam 12-205-2

performer intake with Quadra jet

stock ignition

Please if you feel I am messing up with any of this combo please advise.

Thanks Again
Bill
