Brad47 Posted October 29, 2018 Report Posted October 29, 2018 Short block 230 in place of a long block 218 is it straight forward or is there some modifications to make it work ? The car is a 47 dodge coupe Quote
DJ194950 Posted October 29, 2018 Report Posted October 29, 2018 Short answer- No, they use the exact same block. American build cars and motors. Canadian and exports are another story. As long as both are the 23" long blocks. Go for it! DJ Quote
Brad47 Posted October 30, 2018 Author Report Posted October 30, 2018 That’s for your reply DJ but I was just wondering about putting a 23” where a 25” is currently sitting? Im guess maybe relocating engine mounts ? Quote
Los_Control Posted October 30, 2018 Report Posted October 30, 2018 (edited) A 218 and a 230 are both 23.5" engines, I think it is the crank and rods that change the cubic inches. Neither is a 25" engine and I do not know what is needed to swap. All cars sold in Canada do have the 25" engine as far as everyone claims, .... just saying you need to be clearer on your question.

Andydodge Posted October 30, 2018 Report Posted October 30, 2018 (edited) The key is the OP indicated that he has a long block engine, in theory the short block should bolt to the long block bellhousing BUT there maybe an issue with the starter or flywheel bolt number or arrangement............assuming that is not an issue and the block bolts up to the bellhousing then the front engine mount plate may need some "extensions" from the back edge of the front crossmember to allow the lower two bolts on each side of the engine mount plate to reach and bolt up...........an extension on the water pump/fan flange also exhaust pipe, throttle linkages may also need tweaking..............the long blocks are 218.06, 228, 250 and 265..........the short blocks are 201, 217.8 and 230..............the 217.8 and 218.06 are where the confusion starts...........lol............regards from oz.andyd Edited October 31, 2018 by Andydodge Quote
DJ194950 Posted October 31, 2018 Report Posted October 31, 2018 Boy did I miss some vital inf about your location being Canada and Long block to short block interchanging. Think it may be best for me is allow you to converse with people with the Canadian motors and change info and I DO Not! Sorry to you! ? DJ Quote
Brad47 Posted October 31, 2018 Author Report Posted October 31, 2018 Sorry boys for not getting back in the conversation but I thought I better go see the engine for my self . So long story short the 230 was for sale on CL and I was told it was out of a Fargo and it was a 230 SB he said it was rebuild never fired . I went and looked at it tonight and wouldn’t you know ? It wasn’t a 230 it was a 251 LB and was still wrapped it the plastic from the machine shop with recipes for 2600 just in parts not including the machine shop bill !! all in all I payed 800 and left hope I didn’t over pay ??

Don Coatney Posted October 31, 2018 Report Posted October 31, 2018 My dad who was not a Mopar guy taught me at a young age that the term short block refers to an engine that is missing the bolt on things such as the manifolds, head, and other accessories. A long block is a complete engine ready to install and run. So the term can be confusing when discussing Mopar flathead engines. Quote
Andydodge Posted October 31, 2018 Report Posted October 31, 2018 (edited) I agree with Dons long/short info......I should have included a reference to the 23" or 25" engine block lengths in each of my listings of the relevant engine capacities..........I trust I didn't confuse the issue even more........lol.........thanks, Don........and Brad that price you paid sounds like a great deal, not only an extra 40 cubic inches but rebuilt as well!!.......I'd be pulling the sump, side covers and maybe the head just to be sure but a great deal.......can I take you when I go to buy things?...........lol.........andyd Edited October 31, 2018 by Andydodge Quote
Brad47 Posted October 31, 2018 Author Report Posted October 31, 2018 Yes sorry about the Sb 23” and LB25” it was confusing all around lol the engine is in short block form so the covers and head are still removed and need to be installed hence why the guy called it a short block The head needs to be done still but that’s it ! Everything thing internally in the engine is brand new mint mint !! So I think it should drop in my 47 coupeEasy Quote
