What's in the Box

Info

On your '55-'57 Chevy car, the front motor mounts are at the front of the block and the rear mount attaches to the bellhousing.  This works fine for original use, but makes it hard to swap in a different tranny or add belt driven accessories to the front of the engine.  This mount kit is the solution!

  • Uses common mounts.
  • No welding, but drilling is required.

916-28910 Instructions (pdf)

Specs

  • End to end width = 32-7/8"
  • Center to center width (mounting holes) = 3"

Required rework for parts to fit-see pics

December 21, 2015
The frame brackets that connect the crossmember to the chassis rails were too narrow to fit the crossmember flange putting the bolt holes too close together. (see pics) The flange blocked the edges of the bolt holes and required me to grind for clearance. Additionally the self tapping bolts didn't work well. Large heads and poor cutting ability so I tapped the holes myself. I then used smaller head allen head bolts. BIG disappointment! Supplier or drawings need to be updated. Expected bolt-in and ended up taking twice as long as it should have.
Pros:
  • Heavy Duty Construction
Cons:
  • Bracket Mismatch
  • Hardware Mismatch
  • Required Rework
No, I would not recommend this product.

I purchased a competitors cross member first and when I got it, I wasn't pleased. I tried the fit and wasn't pleased. I started looking for another brand and found Speedways.It's designed much better and was also less expensive.

You will need a different shifter and/or steering column as well as kickdown linkage and a dipstick for the automatic transmission. The list can go on but those are the basics, however it highly depends upon the transmission you have currently versus the transmission you want to change to - not all automatics are the same length. Sorry we do not have a good recommendation for a shop in your area to perform the work. You should do some research and make a well informed decision. We highly suggest that you find someone to do the work before purchasing any parts. They will be a huge help in finding the correct parts as well as saving you expensive labor time if the items do not work together well.

Yes the S shaped brackets will sit on top of the frame and drop down slightly. Then the crossmember rests on top of the brackets and is bolted down. You can see the complete installation instructions here: http://static.speedwaymotors.com/pdf/91628910.pdf

1955-57 had the bell housing mount for the trans and if removing those the cross member 91628910 would take it’s place. If you have the stock front engine mounts you may also want to upgrade to the later side engine mounts if your block is so equipped. Kit number 91018055 would be one example.

Some transmission mounts only have one bolt and for those applications simply drill a hole in the needed location on part number 91628910.

This cross member is for the 55-57 Chevy passenger car and will not be a direct fit to the pickup chassis. We offer universal cross members such as number 91628903 and 91628904 which may be of interest for your application and also the bolt in ends number 91618010 which will eliminate the need for any welding. Verify drop needed for your application prior to ordering.

Part number 91628910 This cross member would be the choice to use on your 1956 Chevy and a Muncie 4 speed. If you were raising or lowering the engine as compared to stock then there would be a need to change the transmission mount height also and in which case the universal cross member would better serve your needs.

Part number 7204175 This cross member has multiple holes for the transmission cushion. It can be used for the Turbo 350, 400, Tremec, and other transmissions. In some cases using the 350 mount on the transmission gives more versatility. Clears most larger exhaust and in some cases simple shimming on the brackets will give additional clearance.

That crossmember part # 91628910 should work to put a 700R4 tranny in a 57 Chevy. You bolt the crossmember to the tranny and put the brackets on the frame bolted to the crossmember loosely and then mark and drill the holes to attach it to the frame. Then bolt it together tightly.
