how bout it im just a local gear head with high hope and alot of questions,i,ve got a 1971 350 engine i just purchased the problem with it is the block is busted at the corner bolt for the outside starter bolt,i also have a 1968 327 part #3914660 not sure of the journal size( if anyone with info please help) can i take the guts from the 350- rods pistons etc.. and interchange with with 327 block without machine work or what would be the best route? PLEASE HELP thanks to all!

 

68 327s have the '350-sized' mains so you can put the 350 parts in the 327 block
this is to say if the bores are the same
you could also have the block repaired...pretty common problem

 

Just had an outside starter bolt repaired in a 400 block. Cost me 75.00.

 

thank you guys very much its hard to get good info on these things sometimes but could i just take it to a machine shop or any good suggestions for the area

 

or you can go 400 crank and stroke it to 383 and have the numbers of a 327 and badge as a 327, leave stock looking like the 327 and have real sleeper looking small block.

 

Usually if you put in a 400 crank, you will have to do some clearancing (grinding). Also the mains will need to be machined larger if you use a stock 400 crank. The aftermarket has 3.75" stroke cranks with 350 mains.

Clearancing of the block yes.....machine work on the mains in the block no. Strokers have been built for many years using 400 cranks in 350 blocks, the 400 mains are turned down .200 to fit the 350 block at STD bearing sizes. The 68 327 block is the large journal block. It's a basicly a 350 block with a 307 crank....which gives you a 327. The 307 was the engine that replaced the 327 about mid year in 1969.
