Re: Which piston for 9.5 to 1 CR
I just PM'ed you.
Great, another little motor guy!!
The 286H cam is too big for 9.5 to 1 CR. Go with either the Duntov or a CC 270S solid and even an Isky Z-20 solid at 9.75 to about 10 to 1 CR.!
Plus, a hy-cam WILL not rev as high before it floats as a solid will! A solid will go as high as the valve springs will let it and you have nerve enough to hold it down!
I have a 280 solid cam in the closet now that I plan on shifting above 8,000 rpm!! It's PAW's $45 el-cheapo, 264/246 jobber that I figure is really a 280/246 cam!! A 301 at 8,000 grand is music to my ears!!
PS., build it like a stock 302 at 10 to 1 CR. or I am thinking about using 6.25" custom rods and 6" rod, 350 roundy-round pistons. Also, look at the 305HO, -601 heads and Fel-pro #1094 shim headgaskets and flat-top pistons.
The -601's run from about 53 to 58 cc's so you have to cc them to know what they are. Great heads that have a double quench chamber much like the old -461 double-hump head, 1.84"/1.50" valves, hard seats and 160+ intake ports!
