250 IL6 to SBC swap
Hey all, I recently developed a pretty bad low end knock in my stock 250. I want to pull the motor and swap out to a small block. I am currently starting with a bone stock 6 cyl truck. If anyone has done this swap, can you tell me what I would need to complete it start to finish? Kind of a parts list cheat sheet if you will, (Fuel line changes? Cross member? Can I use the 3 speed manual I have? etc.) I am sure I can complete the project ina few weeks with good buddies and good brews, but dont want to go in unprepared. Thanks in advance for any insight!
p.s. I know a lot of folks like the old 6 banger, I did too, I think it gives the truck character and was cool to see at shows. However, I daily drive this truck, and tracking down parts, pullies, brackets etc to fix it/rebuild it and add air and ps, is a huge pain. Anyone who has owned one of these 6's will tell you the parts supply and price is a huge con to owning one instead of the sbc. :/ |

Re: 250 IL6 to SBC swap
I'm one who loves the 6 but if I had to replace an engine,I would probably save the money by going to a350 also.The towers and placement are different in the V-8 truck(BB and SB also).The tranny works,IIRC so does the bellhousing and clutch but you will need a flywheel.The bellcrank and mounts for it are different for the V-8 clutch.I'm sure that's not all but someone will probably point out my shortcomings.

Re: 250 IL6 to SBC swap
ttt
It's been many years since I converted mine but I remember the drive shaft was different in length also. I used a complete 350 engine and 350 transmission off a 75 Impala. My advice is to see if you can find an old clunker 68-72 if you can otherwise it's going to take some time to locate what you need. Be sure and check this site's parts for sale section, ebay and even Craigs lists in your state for cities near you.
