Was the ST300 a one year only trans? Or only a one year standard trans in the skylarks? Are bellhousings the same as the TH350?
Check out that rust. Depending on how bad, I wouldn't buy if I didn't have a way to get that taken care of soon. The stuff will spread and cost will go out of control. If it's light surface rust, or something that you can do a little work on to hold what you have got till it gets the right work that's fine, but you can't leave rust alone.
Not 1 year only. Not sure what all prior years got it. TH350 will bolt in place, yes. My 68 has had a TH350 swap.
Ed- yes. The 1967-1969 GS California's were based on post coupe bodies. Basically, the California Buick dealers got together to offer a 'cheap' GS. So, you got the GS grille, GS hood, GS emblems AND the GS 350 'high compression' 350 CI engine. Two issues that you will ALWAYS encounter: the VIN comes back as a special deluxe (which is correct) and the ONLY way to confirm a GS Cali is by ORIGINAL PAPERWORK- build sheet, original window sticker, POP...
Thanks for the info . I've got a 69 2dr post and if it won't sell I think I'll make a clone . Did any have the 455 ? Thanks Ed
...not the post cars. 400" Big Blocks were available in the 2 door GS400 coupe and Convertible. The 400 / 430 / 455 share the same external dimensions and only differ (for the most part) by the cyl. bore size. 99 out of 100 people would never know the difference from a 400 to a 455
