What is the stroke for a stock 400 crank?
3.75-inch stroke
This happens because the 400 small-block uses a 3.75-inch stroke compared with the 350’s 3.48-inch stroke. Add in a 0.030-inch overbore and the displacement formula spits out 382.6 ci, which car crafters have conveniently rounded off to 383.
Can you put a 350 crank in a 400 block?
There are two options for putting the smaller 350 mains into the larger 400 block: spacer bearings used in conjunction with stock-style bearings, or special thicker bearings. We recommend the latter, and you can get them from Speed-Pro or, oddly enough, from Comp Cams.
Does a 383 stroker have a 400 crank?
The GM small block 5.7-liter 350 is the base for the 383 stroker; the 350 crankshaft is exchanged for a GM small block 400 crankshaft. The 400 crankshaft rod journals produce a longer stroke for the engine and create a larger displacement.
How do you tell a 350 from a 400?
Check the bore on the engine if the heads are off. The Chevy 350 cubic inch engine has a 4-inch bore whereas a 400 cubic inch engine has a 4.125-inch bore. The 350 has a 3.48-inch stroke, and the 400 has a 3.75-inch stroke.

How much horsepower does a 377 make?
See all 26 photos Even with four 58mm Weber carbs, the 377 only produced 485 horsepower. Had the cylinder heads been better developed, ported and polished, the output could have been much higher.
How do you tell the difference between a 350 and 400 SBC?
What is the displacement of a 350 bored 30 over?
030″ over, and a . 030″ bored 350 is actually 355 cubic inches.
What’s wrong with a 60 over bore on a 350 SBC?
As many have stated previously there’s nothing wrong with a .60 over bore on a 350 SBC. Now on a 400 SBC that’s pushin it kind of close. Mainly because the 400SBC is a Siamese bore unlike the 350 SBC which is a standard bore.
Will a 383 crankshaft fit on a 350 Block?
The only difference is the 383 mains are 350 size. a 400 crank would need to be ground to fit the 350 block. Now as cheap as cranks are. You can get a 383 crank probably cheaper than refreshing the 400. now for the cubes yes it all depend on the final bore to determine the displacement.
Can I use a stroker bored block on a 350?
My engine is a stroker bored .060″ over. If I had it to do over again I would think twice about using that block as a starting point. However the engine runs strong and no problems after a couple thousand miles. as long as its nothing exotic you should be fine on a 350. Sonic test the block first.
Can a 77 Model 60 run over 350?
Yes is should, but… I’ve been running a 77 model 60 over 350 for 6 years, and I bet that’s about the crappiest year model for 350 blocks other than 76 there was.Also I have a 2 core Griffen radiator which I must say went from one extreme to the other,overheating with an old 3 core to needs to be over 70 outside (21 in Canada) to warm up.
