Getting the motor lower?

67 Camaro, Stock sub frame, LSX with T56 magnum trans, Dirty Dingo sliders. My motor is at a - 6 degree angle, the tranny is as high as it can go without modifying the tunnel, I have a bunch of room under my oil pan (Mast unit) so I would like to lower the front of the motor down. Frame mounts are 69 302 (low and narrow) with the matching Moroso solid mounts, I have also tried the Energy Suspension poly mounts and they sat higher. I tried the 67 SBC mounts that are tall and wide with the matching Energy Suspension mounts and they are worse yet.

I have to use the Dirty Dingo sliders for my headers (Kooks), Tru-turn, and Mast oil pan so I cannot switch to the Holley ones.

Does anyone know any mounts that will set the front of the motor lower than what I have tried?

Thanks,

Rich

Re: Getting the motor lower?

So you want to lower engine as opposed to modding the tunnel?

To do so you can fab frame towers. I would also not use solid mounts.

You will need to lower the engine approx 1"

By lowering the engine you will sacrifice ground clearance for the pan and headers.

Re: Getting the motor lower?

From what I was told from the T56 dealer this setup would not require modding the tunnel that is why I was hoping to avoid doing that. But I also do not want to have clearance issues for the pan/headers. I think I will call the dealer and ask them how they came to their setup without modifying the tunnel.

How did you come to the 1" lower length? With that much the oil pan would not clear the crossmember.

Why not the solid mounts?

Re: Getting the motor lower?

I had my floor all done, dynomat, carpet, seats... If a t-56 would have fit without cutting my just finished interior and with good tail shaft angle I would have used one myself instead of the tko. I didn't think it could be done. I still really don't.

Re: Getting the motor lower?

How much room between the pan and cross member ?

Also, the adapters are side specific I believe. (shot in the dark)

Re: Getting the motor lower?

Every T56 I have installed in a 1st gen has required the tunnel to be raised approx 3/4" therefore my 1" lowering estimate. This has been the case with stock subframe, Speedtech and TCI subframes.

Solid mounts transfer vibration into the car. I like the Energy Suspension Poly mounts.

You can notch the subframe for pan clearance but you will still lose ground clearance and another issue you may run into if you lower the engine is lower radiator hose clearance.as well as possible other clearance issues with the PS pump and A-arms.

Do the headers clear the tru-turn? most headers have to be modified for clearance.

Re: Getting the motor lower?

The Kook headers are supposed to clear the tru-turn if you use them with the Mast oil pan and DD sliders.

I have around 1" at this time under the oil pan for clearance.

I'm going to call today and find out what angle the Kooks headers where setup for and find out from the transmission dealer what they recommend and how they fit this right in a 1st gen car.

Re: Getting the motor lower?

You can run the 6* angle although not ideal if you change your pinion angle. This will however angle the collectors for the headers down as well.

Why not just mod the tunnel and solve all the issues?

This is likely a better easier solution:

X2 That's what I use.

How does the crossmember work with the tranny angled down that much?

Re: Getting the motor lower?

So a question, I'm putting in a Ridetech 4-link so I can control the pinion angle on the rear end. How much of an issue would it be to leave the motor/trans at the 5 degree angle and adjust the rear end with a 5 degree + angle to match the front end? I understand that its not optimal but I would prefer not to have to cut up my transmission tunnel for this.

Thanks,

Rich

I would be worried your wheels MIGHT not be centered in the wheel opening if you adjust the upper bars that much. Driveline vibration And driveshaft clearance in the tunnel are other concerns.

Get out the sawzall and git er done...

Re: Getting the motor lower?

Still need to find out from Kooks what angle their headers are designed for since they are the ones that say to use the DD slider setup.

Re: Getting the motor lower?

Has anyone used the tunnel cover with the stock factory console? It says you can but I want to to know if anyone has done it.

How far are they from the floor? Hard to imagine they are designed for 6 degrees. If they don't get too close to the floor what else is there to be concerned about?
