Thread: Which is better 350,383,400,400 plus?

Tweet

One of my favorite quotes: "There's no replacement for displacement"

Start with maximum cubes and the rest will follow. Should be more reliable torque and power in a bigger motor.

At these 400+ ci, I would opt for a big block over the small block, but that's just my preference.... two ways to make big power: big torque, and big rpms. Start with big torque and you'll spend less time fixing grenaded motors (and more time fixing grenaded trannys, rears, and axles)

two cents,

Chris

It all comes down to application.!!!Exactly what the motor is being used for makes all the difference.

A 1,000 hp sbc is great if you like to work on things all the time.
You know run the valves,change valve springs every 20 th pass or so.

Go big,and at that horse power level there is not big difference in price,500-1000 dollars maybe? Minimal money at that level of hp considering the amount the engine will cost.....Just save room for some rebores on the new aftermarkett block ,dont max bore it the first time.Thats for a small block,a big block seems to be the popular choice at that hp level because of longevity and would cost a few thousand more to build,...but it starts at 454 cubic inches and goes up!!
