here's a little 306 we built up for my 1975 searay.
it's a 1975 block that we decked and torque plate honed. it has a roller cam retrofit kit in it and ported gt-40p heads with roller rocker arms.... dual plane ported manifold and holley 600 with the choke horn milled off...canton seven qt pan with a crank scraper....
