Will it work?Malibu ss 64 Sep 27th, 09, 12:17 PM Going to use a hyd roller from a zz502 http://www.summitracing.com/parts/NAL-12366543/ will 10.4 in comp be to high on pump gas? I also have a set of pistons that will give 8.5 will that work or be to low? Marcus JimM Sep 27th, 09, 05:37 PM To really see where you're at, you'd need to run the full cam and engine specs thru a DCR calculator to figure the dynimic compression ratio, but I think that cam will work at 10 and a half. 67 Plum Sep 27th, 09, 05:39 PM 10.4 may be high with cast iron heads OK if aluminum.Like Jim said need more info. 540Hotrod Sep 27th, 09, 07:13 PM All I can say is I'd use a different cam. There's not a whole lot that cam does that well regardless of compression ratio. JIM | |
