I think the stroke for 377 is 3.48 and I can use that crank in a 400 with spacers? Is there any issues with spacers?

We ran them for a few yrs, no problems at all.

one of the better options is a 400 bearing made by clevite... theyre a really thick bearing that is designed to fit a 400 block and a standard 350 main crank. this is probably a safer option for a race motor as the spacers run the risk of rotating and closing off the oil hole.

Give us a call at McBride Performance at 951-471-2016 and we can help you find these bearings.

We ran that thick Clevite bearing set up for a number of years in a 377 and had zero problems with it! I'd recommend it for sure!
