I met with my engine builder and went over
the old Hutter Sb2 engine... cam was bad in several
areas.. lncorrect spacing on lobes ate it up... going
to use Bullet Cams to make a new one and a 4-7 swap
and he also mentioned 321... Crank is a nice piece, lightened
and journals narrowed.. rods just above a Honda rod..
Pins are a little small so might have to leave compression
at 11-1 but make up in cam timing.. parts are not cheap
but to go 8600-8800 you need to get the good stuff
