Rebuilding LemonWedge.

LW I was looking through my weight loss notes and the K-frame engine brackets that I cut off were 5Lbs plus 4 Lbs more gone by trimming things up, shorter bolts, etc, for what that’s worth. I was thinking about if I was in as deep as you’re going I definitely would be adding some front bars especially now that you’re headed to full race car territory. That 10.00 gets to be a real pain in the *** trip wire and you’re headed that way. Just sayin it might be worth keeping in mind.

I agree.

They make a block off plate, for when heater/AC is removed.
I believe this came from vintage air

 

[LemonWedge]

Current plan is simply make a few small sheetmetal patch panels and apply from the backside with 2-part epoxy. It’s not an AC car, so there’s only two holes for the heater in & out, and the (3) boltholes. We should be able to get them covered with only a few ounces of material.

I tack welded block off panels over all of my heater blower motor, heater hose holes and any other factory holes not being used. If you decide to go with a front plate and even a mid-plate. Don't forget a engine limiter mounting bracket. Similar to this one pictured. I made mine off or the transmission ears to the trash cross member.

View attachment 1949402I believ my limiter. Also welded up the entire firewall, bulkhead and all.

I know where that limiter resides. Mine has not only all the firewall holes welded but the air intake for the heater in the right A pillar and the rubber drain plugs in the floor pan. Good fire protection is something that many don't think about, but they should. car also has a 10lb fire system.

Yes, I also welded little disc's to fill where the rubber plug floor holes were and also run a fire system in my car as well, even though it is a street car that I race. It is mounted on the horizontal bar behind my driver seat.

 

[LemonWedge]

Pretty sobering video, Doug. I had already identified a hole drilled low in the firewall that I’m pretty sure I cut decades ago to pass wires through. I looked at it and could see the backside of the carpet gauze. The first thing that entered my mind was “that stuff is probably pretty flammable, this is an invitation to start the inside of the car on fire!” At the very least, we’re gonna seal up the firewall properly.


I’d love to see pics of B-body motorplate mounting setups. I’ll be running forward bars to brace the frame rails. But I need to know where the motorplate is going land in order to lay that out.

I like the limiter setup run off the transmission ears to the crossmember. I’ve seen it now here and in the “Elephant” thread on Lee’s car. I’ll make that part of the plan as well. But it still seems to me that the motorplate setup leaves the bell housing to hold a lot of weight it wasn’t designed to. I really don’t want to add the complexity of a mid-plate. But would a set of elephant ears run off the backside of the bellhousing bolts at 10 & 2 help there? Or am I overthinking it?

 

[LemonWedge]

Are there any of those 67's that came with a dash pad delete? Is the original dash straight? Don't want to seem like I'm spending your money, but I am thinking lean and mean.

I’m unaware of what tricks the RO23 & WO23, or even the HP2 post cars had up their sleeves. My belief is that Chrysler didn’t do much with these cars other than bolt the Race Hemi between the rails of a stripped down model, and offer them to the known race teams. I think by ‘67, the engineers at Chrysler already had their focus set on the bomb they would unleash in ‘68 with the SS/AH cars.

I need to know what sort of tooling works best to trim these things. Cutting wheel? Sawzall? Scroll saw? Torch? What’s the hot ticket for trimming the double-thickness pinchweld areas of these things?

A 3/8” front motor plate and a couple of limiters and you’re good to go.

This will get you close for plate location. The AR plate sits flat on the frame rails in the right position.

A couple of limiters works well at the trans.

[fullmetaljacket]

I use limiters (Aluminum limiters at that) on the trans ears as well, and so far no issues. Then again, I don't abuse my car for fanfare, only at the track or the $$ run will I let it loose.
Upfront, use a solid plate that goes across at the right thickness, don't use ears on the front because they will flex and bend. The plate stays more sturdier and reacts with the chassis better. A few holes in it like the one on Malex's posted here are not bad at all. Make sure all your measurements, angles, levels and pinion angles are correct before welding any mounting brackets for the plate.
I made mine from scratch, but there are some nice pieces out there in the wild.

LW ,
only 1 extra thing I can think of . Havent seen too many do it . If going to a motorplate I would be measuring and checking to use studs @ waterpump housing where it mounts . Check ARP for separate availability AND broached for allen key . Means even if you pull stuff off front of motor it will be supported also easier assembly . DVW suggestion to machine housing is good though I would prefer to run a gasket .
When deciding on safety / roll cage/bar etc . Its always easier to choose and set a goal and build back from that . My Plymouth has a 5 point rollbar and is limited to 10.00 . Perfect for my goal . I dont wont the extra SFI/cage requirements or moving permanently up a class (BOX). Especially as a street car . Also that 10.00 is about my wallet rev limiter as I am not driven by increased Et etc .I see others with cars too quick and having to slow down as they dont want to fit the safety gear , it makes me laugh a little . As a bracket racer just build to within your ET .
Just my 2 cents worth .

I ran gaskets on the plate on my previous car. After a while they would leak. This car has used Ultra Grey with no gaskets for 13 years, zero leaks. No mid plate in mine. Same trans case and tail housing (1965) since the day it was built . Snout bars outside the engine compartment have two good points. More clearance in the engine compartment, you can tie into the shock towers.. Mine actually are in and out. It was a lot of work as the foward portion of the inner fenders had to be removed and fabbed. Came up with a trick to weld the snout bars to the front hoop. Hole saw the A piller with a 4" hole. Weld the bars, weld the cutout back into the hole. The dash bar is under the dash. Looks better, supports the column and you knees have more room. I have to say every time I see Mikes car I wish I could get to that level. Mines functional, his is like it was done By Dave Kendig.
