C6's are one piece transmissions

 

To the OP. You won't get power and mileage unless you want to put a modern engine in and that will cost more than you'd like and it still wouldn't get great mileage. You have a 5500 lbs+ truck. No engine short of a diesel will get you good mileage. A 302 you will need to spin to death to move it, a 351w a bit less.

Be honest with yourself for your intended goals and budget. Are you really going to bog the truck? Is daily driving and reliability more important? Racing and bogging break parts.

If I were you, work on the 300. It will make good torque, likely the best mileage, and cost you little to maintain (with acception to that damn 1 bbl carb...). They are known to be reliable and last. Keep the 4 speed, it will increase mileage, reliability, and save you money. You are in high school, concentrate on education and future education. Your education in mechanics in general will start with your current set up. Jumping in whole hog will be costly, time consuming and can become a fast way to loose interest. Its easy to get carried away. Ask me how I know all this......

If you don't all ready, buy a vacuum gauge, oil pressure gauge, compression checking gauge, a manual, and diagnose. Ask questions often, and don't look for quick answers without fully understanding cause and effect. This will help build your experience for when you do decide to go whole hog.

 

Would you be willing to sell it?

 

C6's have many different castings, though. I had a C6 with a smallblock bellhousing with a 300 six in front of it. Still single piece, just different pattern.

I'm pretty sure they made 4 different castings for the C6.

 

Yea I thought that they had made a small block c6.

 

They made the C6 to fit: (I'm excluding really old stuff from his)

-all 6 cylinders, Windsor and 351C
-351m, 400 (acceptation being the 1 year FMX 400 block, but I think that was dual drilled), 370, 429, 460 (I think IHI diesels used this with an adapter)
-all FE (360, 390, 428, 427, etc)

available in long, short, and married transfercase tail shafts.

 

I figured they did

 

What are you all needing?

 

Well for now I would like to do an engine swap to some kind of 351 preferably a big block because I would like to do a 460 swap later down the line. So for now I would like to get a 351M and a C6 tranny but I will also need the drive shafts and the cooling lines and ect.

 

351m/400 are not "big blocks", more like mid blocks, they are about 200lbs lighter than a 429/460. The only thing they share with a 429/460 is the bell housing pattern and distributor. You will be so disappointed in the stock 351m, its not worth the swap. Maybe a 400 but if you want a 429/460 just jump to that because your going to have to buy all the swap stuff to go from a 300 to 351m/400 to a 460. If you want 351 cid, then go to a Windsor or Cleveland.

I'm doing a 351m to built 460 swap as we speak. The stock 351m is like 7.5:1 compression, has a retarded timing set and is just plane under powered. I get 10 miles to gallon loaded, unloaded, floored, or downhill with a tail wind.

 

I know that 351M is gonna need to be gone thru... I was told the C6 and transfer case are in working condition but I haven't seen it with my own eyes. What part KS u live in

 

I would but the Cleveland, to my knowledge, needs a different bell housing than the Modified and 460. The Windsor, also to my knowledge, the USED aftermarket parts are hard to come by.

I live in North Eastern Kansas.

 

Did they come with a casting for the 6.9 and 7.3 also?

 

Nope =\
Diesels got there own trannys

 

My dad pulled a 6.9 out of a ford truck. It had an adapter to mate to a ford 429/460 bell.
