I just bought my '72 minus engine and trans. The vin shows the car cam with a 402. I would like to start keeping my eye out for a motor. Am I correct in looking for a 3999290 casting# block? Did any '290 blocks come 4 bolt or were they all two? Also can anyone tell me what to look for to buy the correct trans. i.e. casting #s on case? The car is a 4 spd not an auto.
As long as the originals are missing, why not go ahead and use a 454 block? You can build it as a 454 or 496 and have a lot more power. A 454 block looks just like a 396/402, go for the cubes or you're liable to regret it!
