I recently pulled an engine out of my friends backyard. I tore it down lastweek and started researching the casting numbers. The casting number on the odd numbered cylinder side of the block behind/below the distributer is 3914678. The date code is F 188 (June 18,1968) and it has a sufix code of MS stamped on the deck (even nubered cylinder side). The pistons I punched out were .030 over so it has been punched out. The block hasn't been decked though. My question is: could this be a '68 302 or maybe a Vette 327, or is it just another 350 out of a Chevelle.... This is a great site. Lots of info. If anyone can shed some light on the subject it would be greatly appreciated. Thanks.

1968 350, 2 bolt main, 295 hp, 4 barrel, Camaro/ChevyII, manual trans.

You sir are right on the money

Thank you for your input guys. That was kinda the way I was leaning too.

if the block wasnt decked what are the # on the pad ?

I've got that all written down at my shop. I'm going in for a bit tomorrow. I'll be sure to grab it and let you know.

The numbers on the pad are as follows 18N475006 V07I5MS F18 8 and the little watch face stamping is pionting to the 6 o'clock position. If any of this information is helpful let me know. Also with the 3914678 casting numbercould this number also translate to a 302?

That casting was used with 307 327 302 350 engine's.... VO715MS < Sorry this is designated as a 350. I just needed the # for my records.
