When was the last time you saw one of these (mystery race engine purchase)

If you end up wanting to do a simple solid flat tappet cam I think I have a perfect old isky grind that will get you what you want for numbers.
It's the Z-35 grind. You will get a "great guy" discount.
Also I have an Edelbrock rpm intake 440
That's an awesome grind for that build!
