Finally, the 528 Hemi has been given to it's owner and he is preparing to install it in the '69 Road Runner.

We kept the tune fairly conservative because it was to be driven on pump gas between 0-7000' elevation. The question kept arising, "How much power does a street driven, '69 Road Runner, w/ a 4-spd and 4.10:1 gears need?"

I guess there is a torque "curve" in there somewhere.

Looks like that Road Runner is going to need some serious tire. Wink

Yeah, tire and very careful use of the go pedal. On occasion it's to be driven over the San Bernardino Mountain Range and down to the beach areas of Southern California. Some of those mountain roads are very interesting. Enjoyed having you down and missed seeing your dad. I'd better make an extra attempt to see him next time we're in your area.
