I have come across a free GM inline six and i have no idea what year it is. It has points, a removable intake. What else can i look for to get a better idea what year the engine is? The bellhousing has four bolt holes at the corners whould a sm 420 bolt up to this or do i need a older bellhousing?

Hmm, I dunno. All the info I got on mine came from www.mortec.com, but they only do V-8 chevy stuff I guess

There is a pad right next to where the dist goes in the block. The engine ID will be stamped on it. You might have to scrape off a bunch of crud to see it.Its about 1" wide and 3" long.
he's right...
Yup--right next to the distributor is where the straight 6's have the code stamped...I have several books with listings if you post it here,I can check it for you.....seeing it has points means its a 74 or older motor unless someone put the point type distributor in it..the older ones are best,the motors without the integral head seem to last a lot longer than the ones that do,and the one barrel versions run better than the ones with the integral head and crappy 2SE 2 barrel carbs did...

As far as the bellhousing goes and it was OEM it will bolt up to a 420 just like it would any other tranny in that erra but you will need to verify that is has a 4-11/16" index bore instead of the 5-1/8" used by the 465's .
If it would help you may want to post a pic of the engine and the pulleys that are on it. It could have a replacement block and it might help you if we could identify what year brackets/pulleys that it has on it so that it might be easier for you to get external parts for it.
Good luck , Tom
