383 Build How does it work
Ok I think the 383 uses a 350 block that is notched and a 400 crank shaft is this correct? What I want to know is how would a 400 block be with a 350 crank shaft? What would that be or how would it work?
Thanks

That combo makes a 377" (depends on how much you bore it). It's considered a high revving screamer......but it would just make more sense to build a 400" and gain the cubes.
They rev fine too!

When I was planning my 405 I almost went with a 377 just because my car is a '77 and it would be catchy. I ended up going with a 405, and LT1. Should be fun.
I would suggest either 383 or 400. The 383 would be a killer high RPM high HP engine, and the 400 would be a torque monster.

Thanks guys for the input I probably will keep it all the 400 I was just curious what it would be or even if it would work.
Thanks

RPM limitations are not what they used to be 20-30 years ago. So the whole idea of short stroke high revving motors are just for bench racers and dreamers. IMO there is no real reason to exceed maybe 7500 rpm for a street driven vehicle. The cost to make valve train that can reliable run over 7500 rpm turns into big bucks. Not to mention the rotating assembly.
A smart person would use a blower on a small block or just jump right into big blocks
