Re: '70 Wagon Build Thread*

The kit I have has a pair of extra mounts with a 1" hole.

Re: '70 Wagon Build Thread*

Motor is in. BRP kit worked pretty good, but it went much easier when I pulled the exhaust manifolds. The truck manifold on the drivers side will be close to the distribution block, but I think that is known.

Any thoughts on why my front bumper had the Monte Carlo style parking lamps?

Re: '70 Wagon Build Thread*

Looks really good. Now the real work begins How much body lift to get the trans to fit under the floor?

Re: '70 Wagon Build Thread*

I think about 1" would do it. I don't have the trans crossmember in just yet. It's just sort of sitting there. It's hitting more in the back than in the front, but I'm going to split it like the instructions say here on page 3.

Re: '70 Wagon Build Thread*

BRP 6L90 Trans crossmember: overall it's not bad, but apparently for the wagon they know the holes won't line up yet that's a secret they keep until you call them and ask about the fitment. The holes had to be reamed out to 1/2" on the drivers side and an elongated 1/2" by apex 3/4" on the passengers side.

Step 4:
Once the engine and transmission is lowered into the chassis lift the rear of the transmission
using a floor jack. Install the polyurethane transmission mount on the transmission, making sure
that you install the provided plate between the mount and the transmission (this preloads the
polyurethane mount). Slide the transmission crossmember into the chassis and bolt the mount
loosely to the crossmember using the 7/16”-13 x 1” bolt and the 7/16” flat washer. Mark the
crossmember mounting holes on the frame and drill them out with a 25/64” drill bit.
Install the
3/8”-16 x 1” bolts, flat washers and the 3/8”-16 nylon lock nuts.
It is stated in their instructions that the frame needs to be drilled. Still that is a poor way to build a direct fit part. Spacing on the wagon is no different than a 2 or 4 door car. The cross member should have had slotted holes, at least on one side like the factory did. They claim it is laser cut if so a slotted hole would be easy to do, just a slight programming change.
If it were me I would have slotted the cross member not the frame, actually I wouldn't. It would have been sent back with a clear reason why i chose not to use it.



I modified the stock crossmember to work with the 4L80E to avoid dealing with after market companies. Saved $400, it is at the correct angle and didn't have to cut the floor either.

Re: '70 Wagon Build Thread*

It could be that I didn't use a 25/64 bit <sarcasm>. I couldn't find a 25/64 bit, so I went 7/16. I didn't buy the whole "our (secret) notes say it won't work on a wagon" thing. Like I said, I ended up having to elongate it, but it ended up working as you can see. Realistically, they probably didn't actually fit a 6L90 into a vehicle with their kit. Actually, I'm almost positive they didn't. I guess fab is to be expected, but the kit was a few bucks and one might expect a better fitment.

Re: '70 Wagon Build Thread*

Installed the F-body drivers manifold, which is the side I was having clearance issues with. It doesn't really fit that much better than the truck manifold did, so definitely not worth the money. At this point I'm thinking about using the Hooker manifolds as they look to have better clearance than this one did.

GM F-body p/n's: 12611638 and 12611639.





From below





From above, you can see how it barely clears the distribution block.

Indeed. There's a wealth of knowledge out there that has helped me in my builds, so if I do can help someone else, then all the better.

Re: '70 Wagon Build Thread*

WOW...by the looks of this picture...(the tie rod/oil pan crossmember clearance) with the BRP mounts looks like it must move the engine up by 2 or 3 inches as opposed to using factory style mounts...






Sprech...do you have any pictures of steering box to pump pulley clearance...???

Re: '70 Wagon Build Thread*

Check out the photobucket library, there might be one on there. If there isn't anything good enough, I'll take some when I get back from Chicago. It is close, but it does clear the factory box, but I don't have the ps lines hooked up yet. I'm probably going to order my new box this week. Either the Jeep or Monte Carlo SS box.

Looking at it, the photos in the thread thus far are all that I have as far as pics of the PS pump and box.

Re: '70 Wagon Build Thread*

Here are some pics of the Hooker 8501 HKR's. Overall they fit much better. The passengers side hits the heat shield on the starter and it looks like there is a tab on the 6L90 that might interfere on the drivers side. The plus on the driver's side is that it has plenty of room between the edge of the manifold and the brake distribution block.
