4.030 bore_4.170 stroke_6.200 rod_AFR 205 or 220 head_427ci Windsor. You won't need more than 5,800 rpm.

Cam it right and you have well over 600 hp and have 550+ ft lbs of torque.

If you can't scare yourself with that in a relic, you can't be scared.

Just remember...you don't steer.....you aim.

We did that combination for Shelby when they were trying to set an IROC style series for Shelbys. Mario Andretti and Parnelli Jones told them to take power out if they wanted them to drive them again.

Well, I don’t think Mark Donohue would have agreed with that.

I have no idea. They drove them, he didn't.
