New build, The car : 70 B-body street car. 4-speed 3:54 gear, full exhaust mostly street use. The engine : 30 over 440 block, 4.25 stroke crank, zero deck flat tops, Stealth CNC heads by Modern 950- 4150 Holley , HSC headers, Eddy perf-RPM intake, Hughes roller rockers. I don’t want to over cam the motor and kill torque, but I would think a larger cam would be fine in a larger motor like this and still be very drivable. I was thinking about 250@ 50 , 110 LSA with around 550-560 lift ? Am I in the ballpark? What do you think?

In a 505, the XS282s will not sound like much, ....Count on it...I have the same grind in a mild 440 and with the correct carb, it doesnt have a lot of chop to it. It doesnt sound bad, but in a 500 inch motor it wont have much at all...
A buddy (member upnover) has a very similar combo, cepts its a 511. He is using the next size bigger XE grind. I think its the XS290S, 250/256 @.050. In his 511 it doesnt have much idle to it. Sounds like a small hyd grind....
It sounds mild to the ear, but has gone 11.30s(might go 10.9Xs-11.0Xs when sorted) with unported Stealths, 4k flash, and 3.55s...
My advice...call Dwayne Porter and get it cammed right...
72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72.
Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.
