I saw an ad for a 3.250-stroke Hemi crank.
So I started wondering about how one would build a 9-10,000 rpm engine to run on pump gas.
I thought there were some motorcycle engines that could rev "pretty high", but I don't have a number to put on that.
You couldn't have 15:1 compression, but you probably would need a cam with lot of duration, or.....????
How would you build such a motor ?
Big heads, low compression ?
You not going to do it with factory lifter placement and factory cam tunnel. Would need a staggered lifter pattern in block, preferably a keyway lifter. also would do it with a 55-60 cam with roller bearings.
