Welcome to CHR!

Before you get too far, go buy a book on building small block Chevys like this one - http://www.amazon.com/Vizards-Perfor.../dp/1932494847 Study all the sections and get familiar with common terms and components among the small block.

The engine you're referencing is a non-Vortec replacement (used in a lot of trucks) that is a good solid base to build on. Bear in mind that this is an 8:1 compression ratio engine that will peak at about 5500 RPM - regardless of what intake system you choose. I'd recommend that you download this document and read it.

It fills in all the blanks and actually gives part numbers for Chevrolet flexplate/flywheel, harmonic balancer, intake manifold, distributor and holley 670cfm carburetor. You can buy it all from Summit or source locally.

The document also gives information on headers, H-pipe and exhaust and all the little bit and pieces you'll need.

Break in is critical as this is a flat tappet cam. Use a zinc additive in the oil.

Again, welcome and let us know what you decide!
