360 - Rebuild - Information & Opinions Needed

Hop up on a budget?

Stock carb is good, the edelbrI I is fine.
The cast iron intake is a very good one.
Leave the heads stock. Just use the matching valve springs to the cam which I'll get to In A second.
Mill the head only to make them flat on the bottom. Don't bother with a valve upgrade. Stock valves will do well. No port work.
Ke Th Black or Speed Pro make Hyperutecic pistons at good prices for increased compression, but you'll need to do some math work on IF the deck needs to be killed down for a good ratio. 9.5-1 is the MAX! I'd do with iron heads and a small cam.

The 340 cam is OK but I like the upgrade 340 cam. Similar advertised specs, a bit different at .050 lift. This will not interfere with the pistons at all. Stock or aftermarket.

The '68 / 340 cam is a 4spd trans cam. It is a good cam but rarely seen made.
