SBC to Muncie 4

Discussion in 'The Hokey Ass Message Board' started by Gas Stove-bolt, Mar 23, 2013.

  1. Just a little help needed. I am swapping an inline for a small block. The truck is a 57 with original engine that some-one has stuck a 4 speed behind. I have an early SBC to stick in the truck but want to keep the tranny. Will the bell housing match, or will I need another bell housing?

    Thanks

    The six cylinder bell housing won't bolt up to the SBC.

  5. I think he will need a v8 bellhousing and different starter.

    Conflicting answers here- so did a little looking and this is what is out there that people seem to agree on:

    If your inline is a 230, 250, or 292 the bellhousing is absolutely the same as a V-8.
     
  7. Correct, however his origianl engine would be a 235.

    and are you sure the four speed was a modification? A four speed truck transmission was a factory option
     
  9. It should be the same bellhousing. My old '65 C30 came with a 292, someone put a Pontiac 215 (same as Chevy 230) in it. I took that out and put in a 283. Used the same clutch and bellhousing.

    Yes, a '57 original engine was a 235, V8 won't fit the bell but a V8 bell will accept the Muncie.

    When I swapped a V8 into mine I got another bell housing with the crossmember mounting pads as original. It's been a while but I think it was mostly because of the starter but I cannot be sure or remember. I'd check starter mounting as well as the bolt mounting pattern. :cool:

    I am 95% sure it won't work, the later 65 and up or 62 and up Nova will though, but if i remember correctly you could bolt the later bell to the tranny with a little work it's been a real long time since i played with them.

    If it still has the orig 235 in it, or any other 235 up to and including 1962, the 6 cyl bell housing will not fit the V8. An orig 57 truck V8 bell has just one hole on each side for the crossmember mt. in it, unlike a car bell that has takes a different mt, it has 2 holes per side. I do believe I still have one, but I'll have to wait for the snow to melt to check. :)

    the muncie will fit the mounting holes on the bell, althout the center hole may be larger dia.

  14. Thanks for the info. Last owner told me it was a Muncie and a 235. He owned the truck for 30+ years. It came out of a barn. :D

    We have the Shriner Swap meet coming up, I'll see what I can pick up.

    No. The guys who say the 235 bell won't fit the V8 are correct.

    But...unlike the car bellhousings, the old Chevy truck bellhousings for the 235 have a mounting bolt pattern for the transmission which is the same as the later Chevy transmissions...3 speed and the 4 speed trans...including the Muncie. So I have no problem believing that the previous owner did in fact install a Muncie 4 speed trans in your '57.
