Just weighing up my options at the moments. Yeah I'm not sure if he is wrong about the tranny being a torqueflite or if it is correct as it came off an RB Appollo Fire truck and it seems adaptors did exist to fit them to SBC motors.
He just sent me some pics. Can anyone identify the tranny?

Curious motor, may be quit old. If you can get the part # left side of dizzy bell housing flange and maybe RPO pass front top pad in front of the head. It's got rams horn exhaust manifolds, a local hot rodder would want them.

Yeah that's a Mallory Dizzy.
I've asked for ID numbers.

I'm wondering is it a TH400?

Bummer Shaggy,

I had an alternator seize once, but the belt was slipping past the frozen pulley and still turning the WP. Turned around and limped back home. Good luck on the R&R of the well done SBC. RIP. And Good Wenching!

Currently there are 3 used Chevy engines for sale in the country 1 of which is diesel (I live in Ireland). Nobody here sells new crate engines and importing something as heavy as this is expensive. A 454 will cost me the same as I paid for the van originally.
I'm considering this one a few hours drive from me that comes with the above tranny, if I can sell the tranny on it will make it affordable, but I need to find out what tranny it is first.

Irishman tries to identify tranny...........sounds like a review of The Crying Game movie!

Hey Shaggy, scrolling around to get a picture of a Chevy V8 block bolt pattern. Found this,

https://www.jegs.com/i/JEGS/555/60334/10002/-1

Whatever that transmission in your picture is, it looks like that bellhousing has a very similar bolt pattern to this Jeg's bellhousing.

Jeg's part is a SBC bolt pattern, to Chevy TH400, and Powerglide. IDK if a 350 is the same circular bolt pattern. Couldn't hurt to make a call if needed. But if using your SBC transmission and bell housing, a SBC block should/will bolt up to your existing transmission. Right? smile

Good Wrenching Mate ! !
