Inputs on a home built 318 for red light to red light fun

I don't think some people realize how little of rpm is needed, most stock low powered engines like a 318 make peak power 4000-4500 rpm basic truck powerband, trick for street builds is extend the powerband to 5000 ish rpm peak power without trading too much down low, at this range with the right parts you should be able to 0.9-1:1 hp per Cid.

For hotter street engine move peak power to 5500 rpm for a 1.1:1 hp:Cid but will probably need gears stall since under 2500 rpm will start becoming soft.

This is why most for street say no replacement for displacement cause to this point rpm is kind of fixed so displacement allows more hp to be made at these narrow street rpm ranges.

Above this is more street strip type engine peak power 5500-6500 rpm 1.1-1.4:1 above this your more into race of at least barely street, now there's many ways to do things and I'm sure someone out there has built an 8000 rpm daily drive that get's 25 mpg but this is ruffly how it goes down.
