Chevy 350 V8 To Chevy Inline 6 Swap ASAP
 

Hello, I am looking at swapping out my 350 for a Inline 6, but I have some questions. It would be going in a 1975 Chevy K5 Blazer. Looking at information first to see if I want to buy an inline 6 for my truck.

-How good of an engine is an inline 6 compared to a 350?
-Is a 350 trans a good mate for an inline 6? If not, what automatic transmission do you recommend?
-Where does the motor mount up? What do the brackets look like?
-Are the 250 and 292 the best 2 inline 6's to look for?
-Do inline 6's get better gas mileage than a 350?

Would like to know this information as soon as possible. Thanks

Do you already have a 250 inline with all brackets, pulleys and carb?

If not, you might get off cheaper finding a used 350

If high fuel economy and inline 6 is your goal, then consider a Cummins 6BT.

I do not have an inline 6; I already have a 350 in the K5 right now. I was just seeing other people's opinions on an inline 6 vs. a 350. Thanks

I'm not an inline 6 guru by any stretch but I'm pretty sure the 292 is the better motor just because of the extra cubes. The 6 is a great motor, just no powerhouse. Plenty of torque down low where you do most of your driving, just not a bunch left if you put it on the mat. The TH350 will work fine with it, I'm pretty sure it was a stock option with the 6 in a square. What are you trying to accomplish?

I was just trying to do something different with my K5. A common thing to see is a 350 engine and trans paired together. I don't see a lot of inline 6s' around, so I was thinking about putting one in my K5. Thanks

Here's a thread on a 292 swap into a K5.

If you really want to be unique, how about swapping in.a Ford 4.9 straight six? Much superior to a Chevy 292 IMHO.

Okay; thanks

I think it's still cheaper to build a sbc 350 over and inline 6 but if you decide to build the inline there is a fairly decent community that supports their modification/parts.
