what exactly would you "tune" for a 75 shot on a higher comp engine?
reason i ask is because i have 10.8.1 comp B18B, crower 404's w/stock head...
i have a n.o.s. 75 shot wet kit in my room. do i take it to a dyno and tune my a/f ratio's?
when you pull timming/add more timming does that also affect your a/f ratio?

this would be my first engine i would be dyno tuning so any info on what i should look out for
when tuning would be great . thanks

 

any reputable dyno should be able to do most of the tuning or at least point you in the right direction.

make sure you turn the dizzy back a few deg before you start to avoid detonation. usually retarding the timing will result in a slightly richer mix and advancing will lean it out slightly..
