Olds 350

hi I would like to know if a 73 olds 350 would work in my 66 cj5 with a 225 .I found one four 400 and instead of rebuilding my 225 i was thinking maybe this would work .I have seen on this sight that a buick 350 fits but did not know if olds would, it has the same shape bellhouse just thought some one might know thank in advance.

 

Same bellhousing pattern...but that's all.
Everything else will need to be changed.

 

i know that the grill and raidiator will need changed but do the motor mounts line up as on the buick 350 thanks

 

Seem to remember reading the mounts are different. Here is a little more on size and weight of American engines.
Popular American V8 Engine Dimensions

 

There were Buick, Oldsmobile, Pontiac, and Chevrolet 350's.
All completely different engines.

 

if it's a olds 350 . starter will be on drivers side . not a lot of room over there with ross steering and master cylinder . but any engine swap is possible . just won't be a drop in and bolt up

 

Heavy, compared to a v6 even a Buick 350 comes in 100lbs under the olds and Chevy small blocks.

 

Distributor is in the back of the motor.

 

Sorry to jump in on this thread - What is the most simple engine conversion into a V8 from the Dauntless?

 

'60s Buick V8 300-340-350.

This - but not the 215: Buick V8 engine - Wikipedia

 

And that 350 sounds sooooo good.

 

I have had a couple Olds 350s. As said above, won't work with original ross steering. You have to go to saginaw and swinging pedals. Really heavy motor. Just about everything on them is specific to the motor if I remember right. Not easy to find replacement parts either. At least it wasn't several years ago when I was looking.

 

If you need a flywheel (as opposed to a flex plate), the Olds version is far more scarce. 99.9% of Olds 350s will have a flex plate. You may consider either rebuilding the 225, or find a later 231 even fire from a mid-80s rwd Buick.
