Sounds like a good idea. Should really help with torsional twisting. I have never run a mid plate, but I am seriously thinking about it with my new build. I am using a Quicktime scattershield and want to mount from some extra tabs on the trans flange. This way, I can remove the engine or trans without having to support the other. Plus, like you mentioned, add limiters to stop forward/aft shifting around instead of an engine limiter.

Its really not gonna change a thing being welded in... I have bolted in ones.. the plate still acts as a structural member as does the engine.. the shorter the span from the engine/trans to the verticals that it ties into the stronger it is.. less flex... and spread the bolts a good bit apart (dont put them close together)... a true chassis car the body is along for the ride

Be careful on how far back you set the motor. Two reasons I figure I moved my engine back too far; hard to work on the motor, too high of a percentage on the rear tires. The second part made mine a wheel stand monster when I had the power to run 9.0s to high 8s.

I have the same tubes as Monte show but the sheetmeatal isnt welded in... at the time of the cert on this it certed to 7.50 EDIT I have 2" between the verticals and the engine/trans on the race car.. I have 2" on the pass side and 3"on the drivers side on the Rampage.. I moved the engine to the right a little for added foot room.. and 2" across the top to the cross bar

That's what I have in mind Monte. I will run a tube from side to side on the inside of the firewall off of the front support bars and follow the outline of the mount plate down to the front frame rails. It will almost end up as an X-brace in the middle of the car. I have test fit the motor in place and this modification will only move the motor back about 1" from where it would sit without doing this. I have planned on keeping the top of the carb level but may change that to a degree or two of an angle. The car should not end up with much rake at all.
Greg, how far back did you move your motor? Is it in the drivers compartment? Any pictures?
Thanks for the feedback guys. I haven't really heard anything negative yet about the idea so I think it might be worth doing.
Happy Memorial Day. The angle of the carb doesn't matter. Point the tailshaft directly at the pinion and the driveline angle is what it is.

I will add, don't depend on the Mid Plate for lateral motion control. You'd be surprised how far that will bend if you have a hard launching car. put lateral supports from the chassis to the block as well
