my first 327 engine was the best i've ever had. i have the urge to get another one and build it to the same spec's. it was in my 68 camaro with 12 bolt, 4.10 posi,turbo 400 with 2000 stall. it was bored .030 over(331), trw flat top pistons(10.0:1 comp)64 cc heads, 1.94 intake valves and i believe 1.50 exhaust, holley strip dominator intake, 650 holley double pump, 474" lift,292 dur., erson cam, high volume oil pump. it ran great on the street and it also won a lot of races, of course, not on the street??????? yeah right, those were my dumb years.
and if my kids want to some day go racing, i'd build them that exact engine, but with a little more modifications.
do yourself a favor, and put some money into the cylinder heads. that's where the power is at. and make sure you get parts that are matched for each other. a mis-matched engine will only do one thing and that is bring you headaches. match your power range, of the cam, with the intakes power range, get the right size carb, a good set of heads and a good ignition system and you'll be a happy camper.
