Pulley Diameters

512Stroker said

I upgraded my 340 setup with a Griffin 2 row, 1 1/4 cores radiator, Hi - flow 160 t-stat. Never gets above 180 with A/C on. Yes it has a factory 7 1/4 inch single 3 groove crank pulley and the smallest factory water pump pulley I could find.
Good Luck

I've looked at the Griffin's & they're VERY expensive. I want to exhaust other possibilities before forking over the $$ on a new radiator. I'm sure you understand...

Since my current pulleys are both the same diameter & I don't think that's correct, I figure it's good to put some effort into changing them.

Nice looking engine bay you have & thanks for your help! :thumbsup:
