Used ST-21-108 old racer brown has a few hundred miles on it,was in my 318 way to big went with different cam 100.00 plus shipping from London Ohio 43140 .
Do you like the OD transmission,My Duster with 3.55 rear, and 235/15 tires @60 mph is almost 2000rpm keeps me off the interstates which here are 70mph so the OD would help if I can make it work and the OD trans I can get for 200.00, so was it worth it to you.
I did just put the KB 167 pistons in but was going to replace intake before I put back in car,I bought a Weiand 8007 and have extra gaskets Ill try both see which is better.
Came off running engine,but needs blasted or repaint. 75.00 plus shipping, or will trade for aluminum intake for 318 heads dual plane or single plane. no pay pal will do postal money order.
