318 to stock 340 power level questions.

So……

After having my car sit for 2 years because I haven't wanted to de-tune my original 340 (12.1 compression, solid roll cam, Holley 800DP, Victor 340) I have reached a decision.

Well, the decision was made for me. I just got a 60,000 mile, 1968, 318 that is complete (carb to pan with all brackets and manifolds) for free.


So here is my question.

This 318 build will be using (I have all the stuff below and want a stock looking engine compartment)……….

Stock 68, 340 intake manifold

Stock 68, 340 exhaust manifolds

Stock 68, 340 AVS carb

4 Speed

3.91 gearing

Stock tires

I will be cracking open this 318 and checking everything.

Using the 318 stock bottom end and heads what mods would get me to a stock 1968 340 power level (or close to it given what I will be working with).


I will be setting my original engine on a stand and want this engine for nice reliable street cruising.
