Would I have to find a J code long block? Or could I just use a 68 block with the 70 heads? Or? Sorry all new to me!

No, you claim the engine as a j code and must adhere to the specifications for that engine. The people in tech check to make sure you’re legal, if they check.

Ok thanks for the clarification i appreciate it! I’m just torn between running a 302 or a 390. Car is already set up for 302 and I don’t really feel like going through the troubles for big block swap.

You can't get the Edlebrock Aluminum heads for the 390 any more so that combination would be out for me. The iron 68 heads are hard to find, but it's a good combo. The aluminum head 302 is easy to source parts. 64 289 rated at 203 is a good combo also. Your going to buy rods and pistons anyway, getting a stock crank done (from Castillo Crankshaft service which is near you) at a reasonable price.

Castillo is in the process of retiring due to Health Issues.

There's a reason no one is running the 69/70 302 2bbl combo, the HP is 220, the carb is 1.08 venturi rated at 287 cfm, jmo I looked at doing this years ago and my math says you'd be lucky to run the index.. however the 68 302 rated at 207 with 68 cast iron heads, 4bbl Holley, GT SS is a much better choice..Brian Seaberg 627
