Hello all, my son and I are building a 1950 Chevy Fleetline, we just finished installing a TCI Mustang II IFS and transmission mounts, we're in the process of welding in TCI motor mounts and setting up the motor and transmission. We're using the engine that came out of the car, an old small block chevy(just for mocking it all up, we will be eventually be using a GMPP ZZ383) and a 4L60E transmission(rebuilt tranny with newer version removable bell housing).

We have the engine and tranny bolted together no problem everything lines up, We have the engine and tranny in the car, the tranny is bolted up to the tranny mount.

The starter will not bolt up to the engine with the new tranny installed(it was on the engine and worked with the old tranny). It has interference from the tranny bell housing. Is there a different starter that I will need to use?
I'm aware that there was a switch in the tranny between the small block chevy and the LS1 that the bolt pattern changed, did this change the sytle of bell housing? Is there more than 1 type of bell housing?

Any help would be greatly appreciated! Thank you all in advance!

there are 2 different bolt on bell housing of the 4L60e trans and you must use the proper bell on each trans.

early 4l60e bolt on bell housing has an input shaft with a polished tip at the end of the shaft with O-ring. The smooth area is about 1 inch long. Use this design against the early engine will make things easier for you. The parts all bolt together

Later design 4l60e has splines at the end of the input shaft with an O-ring about 1 inch back from the end. This bell housing is deeper, the pump stator shaft and input shaft are longer too for the converter. The late design bell housing will have a bolt hole located at the ''peak'' of the bell , where the early design does not

regarding the starter, I have been told a ''mini starter'' will bolt up and work well. These design starters do not have the ''snout'' at the end like an OEM starter does.

I am curious what brand of controller you will be using on the 4L60e trans to shift it and control pressures?

Thank you for responding, your info was very helpful.

"The late design bell housing will have a bolt hole located at the ''peak'' of the bell , where the early design does not"

from what you described looks like I have the earlier design, I don't have a bold hole at the "peak".

I took the engine out to put in the Mustang II IFS, then I took the started off to make it easier to put the tranny on. the tranny and engine bolted up perfectly, but when I went to bolt the starter back up the snout of the started interfered with the tranny bell housing.

Another questiion, is there a cover that bolts to the bottom of the tranny to protect the flywheel from getting damaged? If so anybody know where I can purchase it at?

I plan on using a TCI TCU.

Again, thank you so much for the help!

If it looks like this, Salvage yard will be your best bet. The 2 different Bellhousing use 2 different Dust Covers. They also fit Manual Trans. http://www.crateenginesonly.com/Chev...s/10241153.jpg
95 model above for Man. Trans is discontinued, 96-97 model is different, not sure if it's available.
