Anyone have information on a steel Bowtie Block with a casting number of 966286, It's a 350 main and 350 bore (currently bored to 4.060), I'm trying to find the maximum bore limit on this block.

I checked my old catalogs but mostly part numbers are listed not casting numbers.

Unfortunately the part number is gone from when the block was decked. Finding some info using casting numbers but none are the same as the one I have.

Are you sur on the numbers found 366286 is a bow tie aluminum block. I have seen the 400 blocks bored to 4.185 and 4.200 I would think pistons would be custom jmo.

Sonic test your block to see how much material you have to play with....Generally in a race application around .175-.250 on the major thrust side is acceptable.

Yes, I know that number is for an Aluminum block, and I found the specs for that casting number when searching for the one I have. just can't find the 966286 specs.

any luck yet? just curious. when i saw the topic bowtie block a small erection occurred . i wish i could help you build this thing. with all the bad weather, politics, and hatred, a good motor build is a good way to forget about ball sorts of problems.Yes, I know that number is for an Aluminum block, and I found the specs for that casting number when searching for the one I have. just can't find the 966286 specs.

The 184 block can go to around 4.190 , there were other bow tie blocks that can only go to around 4.090 , I would ask on 4m as there's a lot of engine builders there as opposed to toss offs on herei have a bow tie block that is stamped 5.7L casting number 10051184 that is bored to 4.165 and no problems
