Bruce, Do you realize that you just said that 70's Ford small blocks are "retarded"? LOL! Thanks for the chuckle (now you all know how my mind works ... hmm.)

Then you know it's right. I do remember in the 70-80's buying chains/gears for 60's 302/289 motors because the 70's setups where retarded. I would think most performance oriented stuff would be straight up, But HEY,,, that's just ME! Now, where have I seen that before??? :] -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 2004 Grand Cherokee Laredo, 4.7L, Quadratrac II " I realize that death is inevitable.
