What auto would be behind a 250 in a 1975 Chevy Nova? I am looking at an engine/trans swap into a 47 Chevy.
Probably the light duty version of the TH350. They don't have quite as many clutch plates as the V8 version. If it's original, that is.
I dont believe so .The 350 is a non overdrive trans.Another one that will work is the aluminum powerglide but you will likely like the 350 better.
No, not the 200. The one I'm talking about is a TH350, it's just a slightly different version than was used behind the larger engines. They saved a buck by using clutch packs with fewer plates.
many years ago i had a 1976 Chevy Nova with a 250 6 cylinder and th350. that transmission found it's way into a model A ford with a 283......worked just fine for many thousands of miles
So it sounds like the bolt pattern on the 250 is the same as SBC? They are a rare engine here, so hard to get any info/measurements here. Thanks for the replies!
There's a possibility it could also be a TH250; looks like a TH350, but has a band adjustment screw/nut just behind the cooler line ports of the transmission. Then again, it could also be a TH350C or a TH250C, with the lock up torque converter. I am Butch/56sedandelivery.
I didn't realize they had the TH250 in 75...it could be. The lockups came along in 1979, so if it's one of them (with a 4 pin electrical connector near the shifter) it would have been swapped in.
I have a 63 230 truck engine, and a 350 turbo trans from a v-8, can I put them together? flywheel, starter, etc?
should work fine. Make sure the block is drilled for the starter before you get too far. Should be 2 or 3 bolt holes on the bottom of the block, on the p*** side, at the back.
In case you guys haven't noticed, FOR THE MOST PART, (squirrel will know the exceptions) if it bolted up to the back of a SBC, it will bolt up to a 194, 230, 250 and 292. Once again, the interchangeabilty of Chevy parts makes life easy for us of the orange blood.
The only differences have to do with the flywheel, the crank flange changed on small blocks in 86, and the 292 had two different designs, one normal, one with 3 dowels and 1/2" bolts. Also the 400 and 454 had weighted flywheels. And those early engine blocks that weren't drilled for starters.
In 1970 I bought my mom a Nova with 250" 6 and automatic. It was a 200. It had 3 speeds and served her very well for 150k miles. I sold it to a friend whose daughter was going to college. It went on to run well over 200k miles with no major work of any kind. The trans recieved only oil and filter changes at 50k intervals.
Jim your right on that 250's did not arrive until 74. Must have been a 350.. No wonder it lasted so long with no problems.
