Is anyone running a 5 speed, 4wd, behind a 6 cyl? What did you use and why did you pick that transmission?

5 speed for a 250 or 292?
- Thread starter eodcoduto
- Start date
I am pretty sure those engines had the same bellhousing pattern so you can take your pick
I know it’s been done 1000 times but I’m trying to figure out how you mount the starter. The NV 3550 looks like the best transmission but the hardest to find.
How was the starter mounted on those 60s variants with a clutch?
Housing mount, why would that not work?
My 250 with the sm465 is mounted to the bellhousing, I’ll have to do some googling to see how the car bellhousings mount and which one is needed for a T5 or NV 3550.
That was the one thing I forgot about when I posted, those older engines had the starter bolted to the bellhousing.
But what about automatic transmission how did they do the starter?
@tarussell may be familiar with this.
Yeah I could ask my mechanic buddy who just put a 235 in his 1950 chevy pickup he is driving but he's now retired and living in the boonies and probably would answer in a week or two
The 235’s are a different animal and were replaced by the 194, 230, 250 & 292’s series engines in the early sixties.
All the “newer” in-lines share the normal SBC/BBC bell pattern.
And all but the 292 will accept the normal 153/168 tooth flywheels/flexplates - the 292’s crank flange bolts are larger at 1/2” threads and also come with three dowel pins instead of just one and only in the 168 tooth variety as they were never meant for any car applications.
All the blocks are drilled for the “automatic type” starter bolt pattern just as the V8’s are - the ones with manual transmissions that had the cast iron bells ( that took the starter that bolted directly to the bell ) were drilled on the block as well, but once the aluminum bellhousings were introduced in ‘73 they all used the block mounted starters ( C40 & C50 applications still used the cast iron bells ).
Basically the 250’s will accept whatever an internally balanced SBC will so have at it.
Thats great news!
Let me make a correction on the blocks all being drilled for the auto type starters - pre ‘73 blocks there are some that are not drilled just as some SBC’s were missing these holes but there are templates ( same as the SBC templates ) to drill an undrilled block. Most are drilled through.
So I probably remember wrong, he replaced the 235 with a 250.
I remember that the engine that was in it was in bad shape and too costly to rebuild so he found a rebuilt 250 for $600 and slapped it in there and I gave him a sm465 to put behind it because he had a little whimpy transmission and I think he said it wouldn't bolt to the 250
I crawled under there and this 250 is drilled for a starter so its time to gather parts.
