Title: 1967 SS350
Post by: rsms on January 09, 2018, 11:31:39 PM

I have a lead on another interesting car I might try to acquire and wanted to be sure before I go and check it out.  The car has never been restored but the original engine is not in the car, what appears to be the original engine is included but in pieces.  My question is... Would an "MS" 350 have a small journal crank as other 67 and back are or would it be a large journal?  If it is a large journal would it be a 4 bolt main or would that not have happened until the 1969 model year?  If it is small journal obviously ( I think ) it would be a 2 bolt main block. I'm pretty sure the car is legit but I would like to have any info I can to cross check data.   I don't think it matters but the car has a 01D build date from Norwood

'67 engines were small journal, no 4 bolt main. Did you check the engine stamp?

The 1967 350 (and ALL 350's for that matter) was a large journal. Same block as the 327 and 302, which were both small journal, but machined for the large journal crank. And as Doug said, 2 bolt mains. 4 bolt small blocks didn't start until 1969.

Yep, is it’s a 350, it large journal 2.45 inch mains.  (Well medium journal if you consider the 400 small block in the mix which had 2.65 mains).

thanks guys....   I did spend a couple of hours reading on the site last night and finally found this info also.  There is a wealth of knowledge here for sure.  I never realized there were so many L48 cars built.  Are there any numbers known for how many came with the RS option also?

No, Chevrolet didn't keep records of combination of options. The only reason they kept records of options at all was to see if something was successful or not! If they sold a lot, they would bring it back the next year. If it didn't sell very many, it was history!
