Best cam for the street both power & sound

don't forget, you can advance a cam as well....you can install a 110 LSA cam on a 104-106 ICL to close the intake valve sooner and get more cylinder pressure....IIRC it's ground like 4 degrees advanced (106 ICL).

22 years ago, I had the XE262 in a stock long block 360, it felt very healthy with some mild bowl porting in the heads, RPM air gap, headers and a 600 CFM electric choke edelbrock AFB. actual measured comp ratio when I put it together was like 7.8:1. I had cheap mopar torque converter (166K?), 998 tranny (2.74 1st gear, 1.54 2nd) and 3.55's in a 5th avenue and it pulled hard.

idle sounded good, but it still idled with about 14" vaccuum for the power brakes.

realistically for a 318, I'd consider dropping down to something more like the XE256. you have to look at the shape of the lobe, and how quick it opens, too. an old chebby lifter lobe with 276 advertised duration likely has less duration at .050 and .200 lift than one designed for a mopar lifter.

that 360 got replaced by the original short block from the 5th avenue (roller cam motor) with the stock roller cam reground by bullet cams and magnum heads (1.6 rocker ratio). with the thin mopar head gaskets I calculated the compression ratio right at 9:1. the lobe had less total duration and duration at .050 than the XE262, but more at .200 lift (HR259/316 lobe, 259adv [email protected] [email protected] 0.3160 lobe lift/.506 valve lift). exhaust had similar lift but a lobe with about 4 degrees more duration, ground on the factory 112 LSA, and I installed it 6 degrees advanced, on a 106 LSA. same intake/carb/headers as the 360. sounded great but not lumpy, like 16" vaccuum at an 800 RPM idle, pulled as hard as the 360, but got 4mpg better at cruise...
