Re: 1.7 or 1.73 rocker ratio?
I'm considering Comp Cams 1330-16 (1.7 ratio) and 1130-16 (1.73 ratio). Both are Ford engine specific so I feel comfortable with that. The 1130-16 rockers are roughly $100.00 a set more that the 1330-16. Do you believe there will be noticable performance loss with the 1.7 rockers, especially considering it's application? I guess what I'm asking is - Is the extra $100.00 worth the minor extra lift for my engine? I'm somewhat concerned about piston to valve interference with the added lift as well, albeit only about 0.010. I have recessed pistons so I really don't think it will be an issue anyway but I hate to spend the money and find out there is an issue. Maybe I just worry too much................
Any opinion appreciated.
