Getting the most out of a low comp 440

With Jim's low compression build, there's really no reason to get compression to 9:1 or greater if it is a street car. It'll make power. Compression is just one small part of the puzzle. You can make up for it with head work. Some say low compression engines are not as responsive. That's just not true. As long as the parts are matched well it will respond very nicely.
True story...not trying to make 500+ hp so you are correct..9-1 would be just fine..have seen a 440 with 8.69 comp and a 562-300 solid cam work good on pump gas,had ported/milled 906's[77cc]...030..2266 pistons .154 in the hole,team g intake 850 dp in a 69 4spd dart with 4.10's and driving normal got 10mpg on 89 pump gas very responsive and never a ping...just hard to stop...lol
