Hey jhon hollomon
Did you have any troubles with cracking housings or anything? Or was it just fine. Thanks

Tony

I asked the same question before, you get many answers. I run a 3 spd in my mod and I was kinda ify on if I should run a tranny mount. What I did was put a support under where the tranny mount should be on the tranny so it could just rest on the chassis!

We never cracked one under normal conditions but our rear end gears froze up one night and it twisted the bellhousing off. Luckily the three race old bert was ok though!

I would think it's more of a question of what type pf motor mounts you use. If you use a rear plate and OE location mounts you might be alright.

I like the trans mount for the reason above.

good question

We just used the regular solid mounts for the motor and the midplate to hold the tranny.

I had an old mod with a rear tranny mount that you had to use rubber bushings on so it wouldn't crack the tailshaft, We have gone away with that cause we had too many bolts pulled out of it from chassis flex.

This is the second mod that I have owned. The first one had a tranny mount and I never had any kind of problem with it. By the way it sounds a lot of guys run without a rear tranny mount and it works fine. I think that I might try it. Thanks

modman, are you running an automatic or manual???? we brace our manual trans off two ears we welded to the top of the bell housing. we run a brace with a rod eend on each end and bolt it to the side of the tail shaft where the floor shifter mount boss is. i have slso seen a girdel type used that goes under the trans at the tailshaft mount and back up to the top bell housing bolts. the both just take the "bounce" out of the transmission....easier on the bell housing. let me know if you need more info. john

I am currently running an automatic tranny. ATD style. That girdle sounds interesting. Do they make those or is it a home made thing? Thanks Tony

yes, the burt brown article in scr (i think??? maybe circle track???) was the first place i saw the girdle mount. i have since seen them on local cars though they looked home made. real simple deal once you see one. i would say a must have if you're running an automatic. john

2 mounting points make a line, three points make a plane....if the car is absolutly non-flexible mount the engine and trans in 15 places it won't matter...

but since the cars flex, the use of only two mounting points allows the engine/trans assembly to move without binding, stressing or breaking. Can be most any combo of front, mid or rear...generally speaking the front motor plate and rear trans mount is a large span and not the best as the weight will factor and can cause breakage. The front and mid is best as the block is stronger than a transmission and will resist flex and breakage...some FORD guys (us included) know that their blocks don't play by this rule and do break if they run side mounts rather than a motor plate.
