Swapping a gas 350 into a M1009

[Alexander]

Hi All,

I have a 85 M1009 (TH400 and NP20 with about 35000 miles and no engine. The diesel engine was pulled before I got it. I want to keep the stock TH400/NP208 in the unit.

I bought an 88/89 350 blazer with a 700r4 and NP241(I think) to use as an organ donor. The electrical, cooling, and exhaust conversions are something within my knowledge base, but I know nothing about what I’ll have to do about the transmission/torque converter issues.

Can anyone tell me what I’m getting into. Can I use the converter from the M1009? Will there be some vacuum modulator issues? Can I use the original radiator with the transmission oil cooler? Any comments would be appreciated.
Thanks,
Alex

Drop it in The TH400 should bolt right up, and work perfect. The radiator might work, not sure on how things will line up.

It will all bolt right in with no problems!

Toss it in, no worries, should start right up

seems like a good idea to me, what with the price of diesel now, and as such an easy drop in it should give you a sufficient amount of power

Welcome aboard but I think he's already done or should be as he started in 06!

Can't say I've ever seen a 16yr old thread revived lol

OP probably won't see this since he was last seen in 2011. But that old 350 is probably still running, somewhere.

Sorry, it's a pet peeve of mine.
Otherwise, the info is still relevant for someone doing this swap.
