With those volumes, it pays to optimize the design and manufacturing to the nth degree. What gives? Because the 40-gallon is the standard size, they crank them out like potato chips. It's easier to build one of something that's a bit bigger, than it is to build even two of the regular one.

All things being equal, it should be cheaper than doublel. A friend was building a house, and was shocked to find that an 80-gallon water heater was like four times as expensive as a 40-gallon. No parroting.ģ83HT with headers will get you about 330hp and 430lbft, for $4500. But when someone asks how to build a torquey 350, that I can answer from my own experience. If someone asks, 'What should my build be to get 400 HP?', I don't have a good answer, and so I won't offer an answer. It is in fact what I did, with the same goal as the OP, and I know it works and is within the scope of most guys working in their garage. The advantage of my answer is that it isn't a 'Well, on my next build I think I will go with' build, or a 'I know this guy and what he did is' build. And that worked out great, and I couldn't be happier.

I had the stock engine, I replaced it with the 350/290 crate engine, which sucked in a truck, then I re-cammed that with the 12-300-4, which is the about the most torque you can get with stock lift. My own goal with the current setup was a torquer engine. The forums get the same question a lot - how to build a torquer engine - and when we do, I give the same answer every time. I knew that, mis-typed and didn't spot it.
