CPP tubular engine & trans crossmembers

Got the engine crossmember the other day & the trans crossmember is on its way. No instructions with the one for the engine and the only thing I found on their website shows it being used to put a Chevy SB in a Ford truck. I am building a 56 TF truck. Searching on here I found a couple posts where guys reported having issues with it coming in contact with the front axle on hard bumps. So messing with it I see that it can be turned around so it either has the drop section facing forward (which puts it above the front axle) or it can have the drop to the rear which gives plenty of room as they did in the video using it on a Ford. I have tried it both ways on the empty engine I'm using to do my mock up stuff and it easily clears the oil pan either way. Second question has to do with the end caps for the engine crossmember. They can be mounted 2 ways. With them having the longest part of the rectangular flange laying on the frame or stood on end. Which way I mount them has the effect of raising or lowering the engine about an inch. CPP tech support was ZERO help. They basically told me it's a universal kit and that I can mount it anyway I want to. That's all fine and I used to build racecars & this ain't my first rodeo so I'm perfectly capable. Just want feedback from guys who have been here & done it. When the trans crossmember arrives my plan is to position both mounts prior to removing the cab so I can make sure I have clearance for the distributor. I also plan to upgrade the brakes with an under the cab power booster & master cylinder. So... Who has done this swap using BOTH these parts and what tips can you give me ? The search feature here leaves alot to be desired and when I do try to find old threads about this I come up with all kinds of useless info concerning much newer trucks that have a totally different set of potential problems. Pics to show what I'm talking about.

Re: CPP tubular engine & trans crossmembers

Look at the tubular mount from the side the area where the motor mount attaches to small tubes should have a slight angle pointing down ward, that faces rear of frame. Then mount on engine next leave the the ends loose and set up the motor with distributor enough room that you can remove it from block and enough room so you can turn the dist by hand. The ends can actually be welded either way thats up to you as long as the motor clears your cross steering shaft, tie rods. I put a bubble level on carb mounting surface to insure the motor is level. Hope this helps.

Great pics. Thanks ! That shows the crossmember with the "dip" facing to the rear the way I will probably install mine. However it can go either way and in almost all the cases where it was installed with the dip towards the front guys mentioned having problems with it coming too close to the front axle. This of course, is only on those trucks that kept the stock axle. Very helpful.

Re: CPP tubular engine & trans crossmembers

That's a problem you run into with something that is "universal" sometimes you have to ponder and figure out just how to make it work the best. I think they don't give much in the way of instructions simply because those crossmembers are used in so many different applications. The last one I did was in a 56 Dodge pickup that I pulled a Desoto Hemi out of (tired but it's in my milkhouse) and put a mid 70's 350 in. That worked out pretty well and saved a lot of fabricating.

Re: CPP tubular engine & trans crossmembers

Hang your engine and trans on your hoist,

hover it in the engine bay,

mount the cross members to the engine and trans,

find the best location,

Level Side to side and front to rear using the manifold carb mounting surface,

bolt to chassis, Tack weld the cross members to the end parts,

remove engine,

finish weld the pieces .

This assumes the cab is in place. Don't be surprised if the trans mount is below the frame rail.
BTW the driveshaft will need to clear the next factory cross member through in its range of motion.
