Oops I was trying to show a picture of what I bought to help identify if it is a 283 or a 310. Maybe someone can helps anyways.

The engine came out of a 1850 gas, not sure of the year. It has a canister oil filter ahead of the distributor and a 3 groove pulley on the crank shaft.

Some said they mostly put 283s in the 1850s and am just wondering if that is accurate.
 
Engine model number should be on the
side of the engine block. Cast into
the block. Seems that it may be the
last 3 digits in a longer number.
 
No, the 283 gas engine came in the 1750 and 1755. The 1850 gas should be a 310 if it's the original engine. The only real difference is the crankshaft (4" vs 4-3/8" stroke) and pistons with a different pin height.
 
Thanks for the info. Its going into a 77 after the season winds down. Right now the 77 has the original block with a big bore kit and a 770 head. 250 cubic inches it pretty fun now but hoping for a little more at the brush pulls up to 5000 lbs or so.

What is the path of least resistance for getting the bigger engine in there? 1650 water pump, 880 bell housing / plate and starter? Would a 88 tub be easier?

88 tub would be much easier as the input shaft doesnot need to be shortened. Chuck
