I don't know all the aprticulars but it is a +.030 over late 60's 440 with 9.5/1 hyper pistons, ported stock cast heads (not familiar with the casting numbers for big block), a CH4B Edelbrock intake, a Demon carb (I believe it's a 750) and a stock electronic dist. The cam is a Comp XE275 HL-10 with .525/.525 275°/287° @ 110° c/l. It was dynoe'd with headers of course and Joe has headers and 2 1/2" exhaust with electric cut outs. I think it will be a nice bump from his stock 383 he has in the re now. HP 468 TQ 505 @5500 rpm. @dukeboy_318
Sounds like the right combo to make those kind of numbers. My 360 Mopar Performance crate motor with cast heads was making around 410 hp with a similar cam and an M1 single plane/750 eddy with 9:1 compression before I tuned it down to where it is now. It was all high rpm power though, which is why I dialed it back for the street.
