Engine is pulled - 273 rebuild or replacement 360 crate?

[NC Engine Builder]

Well right now the Magnum has all kinds of wires and hoses hanging off it, plus plug proctector tubes that make it look like a rusty porcupine.

I’ll hold off judging until we clean it up a bit.

Your going to be removing all that stuff

So been a month and now we’re back at it. Final decision is to build the 318 it’s all disassembled and ready to go to the machine shop. On Tuesday I’m going to spec out the engine with the builder and buy the parts. I’ll post what we decide on. The builder thinks we can get over 400hp out of the 318. Fire away!

We strongly considered building the 273 by going .12 over (it’s already .060) and using Chevy 305 pistons. However it turns out there is a cast crank in that 66 block. I was expecting forged. There was also metal debris of uncertain origin in the oil pan.

So best to move on to the 318. I’ll post our spec parts Tuesday or Wednesday.

here's a basic recipe

318 Engine Build - A Parts Book 400HP 318

Check out the build of an LA based 318ci engine that makes 400hp on pump gas from Mopar Muscle Magazine

www.hotrod.com

i'd deviate from that and substitute some type of aluminum head: speedmaster, afr, eddy what have you.

stay in the same ball park on the cam and you'll see at or near the 400 target.
