The whole idea is to use a free block and cheap components to build a usable street motor. I've suggested Magnum heads in the past but they will require bore notching, which member Bigblockranger did in the car with a Dremel using coffee filters in the block to catch the chips. Hardly high tech!

Or home port a set of 302s.

If building a high rpm motor I would use expensive components and most likely build a much larger engine.

For this build it is max out the cubic inches, keep the rpm manageable and use a relatively cheap valvetrain.
