Hello there I am going to be doing a engine swap and wanted to know if anyone has done this before…I’m sure someone has. I have a 1988 G10 305 efi with 700r4 transmission. I’ve read on forums that mounting brackets are the same for the 250 inlines as the v8s. They look the same to me anyways. The inline is going to be a single carb. Not really building anything serious as I’m using this 250 to get by. Dude sold it to me for $150 so I couldn’t say no. Should I be worried about the computer in my 88 or will that not matter much? Any and all information will be very appreciated and I look forward to the responses

Welcome Kami,

Good luck! I did the same V8 to 250 inline six in a '65 Impala. I suggest obtaining the entire 6 cyl mounts. Your experience may vary, it was not a direct bolt in for me, at 16. The mounts were different. Usually, Chevy is not like this, but the bottom mounting plate to frame for my application was different. No problem. Ordered the parts from Chevy. 1974. It well well. By 50%. lol

After Chevy sent one same side mounting plate wrong 3 times, Chevy parts guy threw up his hands and said sorry Son. I chained down the motor on the high side and let 'er rip. That was after I figured put I'd better do that because the motor would lift and disconnect the shift linkage at the Powerglide.

Computer was no issue for me, V8 TBI, onto that I-6 will be interesting.
Good wrenching!! We're here to help. This is a good one! welcome

TBI won't work on the six at all.

Should be able to find a junkyard 350 or other SBC Smallblock. As long as its a TBI motor with the sensors it will hook right up.

I just found a complete 1988 5.2 Dodge engine complete with all rotating assemblies, distributor, engine harness, TBI $1500

Good Wrenching!
