Hello from Reno NV

Don't know how fast you go, but an engine builder named Russ Barfield who is still working inspite of being in his high 70's, had a Plymouth Valiant in 1963 with a slant six than ran 13.0 and over 112 mph. The six cylinder truck engines used a double roller timing set and shared the same chain as the Hemi. I don't know if that set is still available. The chain is, but the cam gear might be hard to find. You could check with Cloyes. You also have a pretty good torque convertor builder in Reno called Yank Performance. Nice to see someone doing something different.
