L16/18/20B best street build- advice needed.

I am NOT looking to create a 200hp, fuel injected, or turbo motor with dreams or visions of winning ANY races.

My son and I just want to build a good, reliable, drivable, fun, spunky, MUCH IMPROVED VERSION, of this legendary 4 banger.

I already have all three types of engines (and then some), numerous intake manifold‘s, exhaust manifolds, blocks, and heads from every generation (up to ‘78) of L16/18/20B.

Lots of stock parts and pieces to choose from.

I don’t mind shaving, shimming, porting, polishing, or boring. And I wouldn’t mind bolting on a better carb, and better ignition.

I don’t live in California, and I don’t believe that emissions are going to be a problem here in Texas!

I am going to be rebuilding the engine anyway, so I might as well use all my parts and pieces, and do it right the first time.

This will be going into a 1977 620 pick up truck.

So guys, those are the facts! What do you have for me: the best recipe, your best build for streetabilaty and fun?

Thanks in advance! GP

Welcome to NICO.

A friendly bit of advice. Cross-posting (i.e. posting the same topic/message in more than one forum board) is frowned upon. It's confusing and often counterproductive. Please choose the forum that is closest to your post, and place it there only. If you should create a post in one forum, and later realize it would be more appropriate in another forum, please delete the original before posting it again. Thanks!

Ok, will do... sorry about that. Where do you think this particular question would receive the most relevant and helpful responses? I’ll only post it there.
