Overlap determines the idle chop. higher the number , rougher the idle .

Also as mentionned previously as well, the type of exhaust does affect the note as well (chambered, spiral, catback, duals, straight thru etc.....)

Int 237 + Exh 242 = 479 / 4 = 119.75 - 112 Lsa = 7.75 * 2 = 15.5 overlap

Gosh by that calculation my 231/237 cam is 10 degree overlap. I think it lopes pretty good but at the same time the TREX is 2.5x as lopey. I think mines just right

Going by actually hearing the different camshafts, I'd say G5X4. Going by the amount of overlap, T-REX has the most at 25 degrees. G5X4 only has 18 degrees.

boy I wish i had a video camera so i could give you guys a sound clip of the t-rex through straight pipes, ricers dont appreciate the sound very much as a matter of fact I think some of them **** themselves at the stop light lol
