To put the 230 in would require a considerable amount of fabrication, the motor mounts are different, bellhousing is different to name a couple things. | | | | | Joined: Jul 2013 Posts: 224 Shop Shark | | Shop Shark Joined: Jul 2013 Posts: 224 | Did not know any of that .... Thank you .... it's the 235....

I just switched from a 235 to a 230 in my 54 3100. The ONLY thing that needed fabricated was a front engine mount... which was pretty darn simple! I didn't have to move the radiator, or change the bellhousing crossmember or anything.
To use a 230... need to fab a front engine mount, and you need the bellhousing that goes with that engine (has a V8 pattern to attach to the motor i believe). The bellhousing uses the same crossmember mounting locations/angles as the 54/55 1st. Now thats only if you're using a manual transmission... an automatic would take a bit more work.

This is due to being the first year to use the new angle mounts on the bellhousing. That mount design is the same as the 230 and many other newer style engines.

I was looking at the name for the type of truck, not the post (whoops!). But still! just some careful measuring, cutting, and welding of that crossmember and he'd be good to go! I know I saw it somewhere on here a while ago. But, I still stand corrected! I need to pay closer attention about the details!

It is a much more advanced engine design.
I like 235's though.

the 230 is newer (not ALWAYS better), has 7 main bearing caps vs 4 main bearing caps... makes it a little more comfortable at sustained higher RPMS, the 230 has a bit more HP (I've seen it rated from 140-155), the 230 has an integrated full flow oil filter, versus a bypass filter, and I'm sure there are many more differences (but I'm no expert).
It all depends on what you want for that truck. | | | | | Joined: Sep 2011 Posts: 1,453 'Bolter | | 'Bolter Joined: Sep 2011 Posts: 1,453 | 230 is a 7 main bearing engine with individual rockers(no shafts).
