I SEE IT THE OTHER WAY AROUND, I see 10 + old timers with lots of Pontiac Experience saying build the 428 engine and drop it in the 2+2.
Building a 428 from pieces is painful at times but he has the majority of parts in a complete engine with needing a compression ratio drop to run today's pump fuel. GOOD pistons are available from Ross, Diamond, JE, among others. I have a set of custom WISECO Forged Pistons with a custom Compression Height. (Also known as a "Dial in your own Compression Ratio") and I have plenty of valve to piston clearance with the camshaft I run.
Good rods, custom pistons and rings for a minimum bore job on the 428 block and 670 heads and you are good to go.
