starter bolt pattern on 400 SBC?
I know that on 350 blocks - you can find the offset and straight bolt pattern for starter motors. Corvette blocks usually use offset bolt pattern.. I wonder if 400 blocks are available with both patterns or if they are always a certain pattern??

Good luck,

I just went out to my garage and checked my 400...it's sitting on my engine stand. Mine has a mounting hole with threads inline. It appears that either type of starter will work...at least on my particular block.
Do you have your engine handy? For $50.00 + dollars, I would check it for the dual mounts.
Good luck,
Jeff

My '73 406 has an offset starter bolt pattern. I used a CVR starter part # 5323OS.
It is a Canadian made unit, very high quality, and it cost me $130 CAN or about $110 US

If the block doesn't have both patterns the extra hole can be drilled and tapped. That's what I had to do with my 350 when I went to the small flywheel. And with the engine out of the car it would be so much easier, I did mine from below while the car was on the hoist.
