Hi, I was wondering if i was to change my 350 cid LS1 engine into a 383 stroker what would be the best heads, cam, and the best size of fuel injectors to make the engine run great, have over 400 hp and still get ok fuel economy. I appreciate the help a lot, thank you.

You can easily make 400 RWHP with the stock cubed LS1 and a good cam. Tune would be needed as well.

the ls1 (346) can easily make close to or over 400 cam only on stock cubes and still have good gas mileage. Its all about the tune.

heads would be the AFRs. cam depends on if you want it streetable or not.
with a 224 cam, headers, ls6 intake , lid, and tuning, im putting down 379 rwho.

Heads, cam, and cubic inch increases will affect your mileage greatly, if you are concerned about that I would build it up on 346ci.

Yeah, if you only want 400hp, you don't need to turn it into a stroker.

It kinda comes down to POWER vs. Fuel economy. With our cars, you do get an impressive amount of both. But, when you increase power (unless you do it by removing restrictions), you have to get the power somewhere. It takes fuel to make power.
