no 400 block

but if your de-stroking a engine... build a 352.....  they are nasty engines... you just use a 237 crank not a 350 crank

more rpm's

what is this a 283 crank in a 350 block

no a 283 crank in a 350 block makes a 302 if it's stock bore

how do u get the 352 then

[ballistics-10]

400 block with 283 crank

[Jjay78]

400 block with 283 crank

actually that's only 320 cid...with a stock bore.. and with a 327 crank it would be a 347, and a 372 with a 350 crank.. but a 283 with a 400 crank would be a 354

On the subject of 6.0" rods vs 5.7" rods they both have there up and down sides. My information comes from information I have gathered from planning my 383 build. I am not a professional engine build but the information I am giving came from some very well known builders along with my own hours and hours of research. If what I am posting is wrong please correct me.

The 2 best things about 6.0" rods are more rotating mass so more torque. The other is that a 6.0" rod will have a smaller angle of deflection on the piston to the wall. The 6.0" rod being longer does not put as much lateral (sideways) force on the piston into the cylinder wall. See the picture below. Nothing in the picture is to scale just a quick drawing I made to show what I am saying. This is over-exaggerated to show the difference. The red rod is the 6.0" rod and the blue rod is the 5.7" rod. If you picture the crankshaft rotating clockwise you will see how shorter rod puts more force shoving the piston into the wall than the longer rod.



The plus sides to 5.7" rods is the already stated wrist pin locations (keeping the wrist pin lower and out of the piston rings). The other is less rotating mass so they spin up the RPM's faster and easier.

It all depends on what you want to do.

Gotta watch out for clearance issues with the crank/rod/piston skirt assembly when ya get to changin these things around. They dont always tell everything in the forums. Sometimes ya gotta do a little grindin in there
