Resto or mild streeter, fine..............Race car, no

As far as what guys did back in the 60s and ran fast. FAST is a relative term. What so called "race" motors made for power and ran back then, is slow by todays standards.

How much faster is an A/Stock car now as compared to the 70s...........same parts, as far as block heads and most rules. They make WAY more power now.

You want to run a busted up factory block in your car, fine.........but if you were next to me, I would just hope it had a diaper on it. And some can call is BS all they want. Don't change the facts, that a repaired block is considerably weakened.

We just had to trash a $6000 alum block that was cracked the same way, that had several hundred runs on it. Could it have been welded, yes.....us use it, HELL no. Stuff fatigues, cracks and doesn't last forever.
