tdmainos67 Aug 29th, 04, 11:44 AM I am having my 454 bored 30 over not by choice the cylinder walls require it, What CID will this give me? would this change my cam selection, I am not planning on doing anything radical, I want to run stock exhaust and the heads are getting your basic valve job(oval port), I want that lopping idle sound).... does anyone have advise on the cam I should use ? :confused: Thanks JIM Aug 29th, 04, 12:06 PM a .030 over 454 gives you approximately 460 cubes. Bob West Aug 29th, 04, 4:11 PM I use 454 + .060 is 468...so half that 461??? rounded down to Jims 460 smile.gif but then they'll ask you what you're doing with a Ferd motor in a chevy pdq67 Aug 29th, 04, 4:43 PM A great daily driver BB cam is the good old CC 268HE or one about like it!! Should pull like a locomotive AND still have just the hint of a lope to it!! Want more lope, then try the CC 270 magnum..... But if you are still low compressioned, no bigger b/c the 280 Magnum really needs up close to 10 to 1 CR., and preferably above to run it's best, imho... pdq67 DZAUTO Aug 29th, 04, 5:46 PM 454+.030=461 454+.060=468 454+.060+1/4in stroke(4.25)=496----This one right here is probably the most bang for the buck if you already have a good 454 for rebuild! tdmainos67 Aug 29th, 04, 6:49 PM Thanks for your help guys 1BAD70SS Aug 29th, 04, 7:21 PM bore x bore x stroke x .7854 x number of cylinders = cubic inches | ||
