chevy starter bolt pattern

[chevy art]

my buddy had an sbc engine built by a roundy round engine builder that was built for a street car. he ued all old blocks and steel heads with no explanation why. even used a solid flat tappet cam that only goes up to 6200 rpms and dont really start working till 4000 rpms and there is poor vacuum for the power brakes. thing i dont understand the most is why he used a starter with only 2 bolt holes(only 2 holes in block) and a 153 tooth flexplate. what years was this starter flexplate combo used. thanks Art

Almost every year the SBC was offered; in some vehicle or another. Never in a 400 though.

How much did he pay for the engine, and what were the customers demands? Sounds like he used a bunch of stuff he had around and built an engine. I like iron heads, so I use them for most of my own builds. Cam sounds like a roundy, round cam. Also, many of the roundy round cars use the 153 tooth flywheels and starters. Sounds like standard stuff the builder is familiar with.

Pretty sure a few of my SBC auto cars came with a 153 flexplate stock, my C4 for example. All the factory and aftermarket starters I have/had were 2 bolt, I forgot there even was a 3 bolt aftermarket version.
