i was wondering how well this combo would work for a street car. 306ci shortblock(stock compression, etc..) thumper heads, explorer upper and lower, b or e cam, 150hp wet shot, and hpipe w/ flowmasters. this would be going on a basicaly stock 87 speed density 5speed. how much whp would i see, i know its hard to say but estimated. also, does anybody know the compression ratio with stock piston and thumper heads? how big of a differance would a maf conversion make with this combo?
