I am planning to build a modest street motor for my 66 Fast back and I want to make sure it is a roller cam block. What is a quick way to ID a bare block?

TIA

If all you're concerned with is whether a 302 block is a roller or not...
Engineering number that starts with E5 or 'higher', i.e. E6, E7, F1, F4, etc. is a roller.
Engineering number that starts with E0, E1, E2, E3, or E4 is NOT a roller.
Engineering number that starts with D or C is NOT a roller.

For 351W block...
Engineering number that starts with F4 or 'higher' is a roller.
Engineering number that starts with F3 or 'lower' is NOT a roller.

If you want to know what make, model, and exact year (engineering number is not the model year) the block is out of I need the partial VIN stamped on the block.

I assume I have to change the oil pan and the oil pump pickup. Will stock 289 parts work?

I have a set of 15" X 8" steel GT style wheels with standard offset. How large a tire can I go with front & rear?

TIA
