this block is riddled with markings, here are the other three corners.

Likely scenario as this engine has flat top pistons and from what the barn has told me '37 should have domed pistons. A lot can happen in 80+ years. Leon, It is my understanding bonderizing is a form of a phosphating process or parkerizing.

Thanks jack! So that is a factory stamping?

H S B, I am assuming this might be from a rebuild at some point in its life but this block also appears to be a stock bore with tin sleeves. 21 stud 37 or early '38. Does anyone have any info on these markings? Thank you- Douglas

Thanks for that info, Jack. It does appear to be a difficult size to find. Not boring this out to its limit also seems like a good idea even with the advance of the 4th ring with the 8ba. I will call some piston manufacturers and see what a custom set runs these days.

Thanks Terry. Jack, it will be going into a fenderless model A coupe. It appears to be a standard bore with some tin sleeves currently. Maybe i can push it out to an 8BA standard piston size and shave a Stock '37 head down. I will have to see what pistons are available.

thanks for that info Terry & jack looking on Vanpelts site they give two different compression ratios for '37 aluminum vs CI Is this just a CC Head difference or are different pistons used? Would a Domed '37 piston work with a '36 head with clearancing? 1935 221 3.0625 x 3.750 85 6.30:1...

I have recently acquired a '37 short block with flat top pistons and have been looking for a set of heads. That search has brought me to flat top or domed heads but I can not seem to figure out if that was based on year or did they have both as a option on all the years? Did the compression stay...

much respect to you, Scicala. For letting me know about the rockers for sale!

Thanks Dobie for that! the first photo shows it on lift and the 2nd shows it on base circle. I have sent a check out to Ahshoe for the rail rockers and i will check the length of the pushrods tonight.

looking at the side by side shot of those rockers it seems the rail style has a greater distance from pivot to valve tip, which would make my problem worse. Maybe i will order one rocker just to make sure before buying a set. thanks for the link!

thank you all for the info! i guess i will measure the pushrods first and then check them for hardness, then order a set of rail style rockers for it.

i am assembling a customers basket case '36 ford truck that had this rebuilt 289 with it. i was getting ready to bench run the motor and wanted to make sure the valves were adjusted correctly when i noticed the rockers hanging off the tip of the valve. Now by the stick out of the valve past the...
