my point exactly too many variables for a non engineer
so buy a set with one of the names mentioned or get a melling, cloyes etc
for example cloyes makes a gear set for the racing Iron duke pontiac with a iron or steel cam gear instead of aluminum or fiber- which get destroyed with the shaking 4 banger
This gear set also works on a chevy 194-292 chevy 6- which I run
good engineers solving a real problem
remember all chain designs do not interchange with all gears- they gotta match if you are just getting a new chain
what does everyone think of the tensioners/ idlers for the SBM?
