pat no there off the shelf rods.. you can get 7" full floaters or press pin right off there web site...can't remember the dam part number.. i called around and every caddy site that sold racing stuff for them wouldn't give any spec's intill some dumb kid sliped up and said that scat was making rods for caddy engine..looked them up and the small end was the same as a big blck chevy and the comp height from a chevy would work if just took .020 off the deck. the pistons are off the shelf bbc just .070 over they could come from any brand flat tops. flat tops give a comp ratio of 12.21to1 and a dish bbc piston will give you 10to1 nice friendly pump gas engine..CANADIANAL THE POWER WAS AT 6400RPM that's fine i have a piston that's half the weight then the factory one with a lot bettter rods and bolts. the factory piston was over 1200grams with pins. the bbc pistons are 640grams. it made 600+ftq at 2500 and at 3000 rmps it was 667ftq and stayed there intill it was 690+ at 4900 and stayed there intill 5700rmp when it droped to 630ftq...
