Built my son a motor for his race kart.
preditor hemi
Arc billet rod
Arc flywheel
6 degree advance key
Big valve head 32/28
Ported polished epoxy coated
1.3:1 rockers
Nr racing .670 methanol carb
Valves intake set to .003 exhaust .004
Coil spacing everywhere from .020 to .065
our issue is it won’t rev up the most I can get out of it is 6200-6400. Everything says this should pull like a monster to 8000 plus.
any ideas?
