They look nice, I bet they are better than some guys over here running MW SR 650's whatever that means... in a '69 Cuda notchback has a small s/roller, ally indy block 572 cubes @ 14:1.with a 440-2/old 1050 Dominator, 2900lb all in brkt car runs 10.0's>9.90's@129, has been 70's@130>says it all, what a waste of an easy 8 sec potential car and C16 with better heads/cam, pains me to watch it run with so much $$$ in the block going so slow.
