Who makes the best frame pads - 455 into a 67

What will I need for the 455 conversion into a 1967 Special - new frame pads and stock motor mounts or modified motor mounts? I see Poston, TA and PAE make the pads/mounts - which are the best way to go - ie the least trouble? :Brow:

I bought mine from PAE-- Jim has a great rep around here. Fitment was spot-on!

 

Unless the others have changed, TA mounts are the only ones made to fit to the only mounts available (the newer style mounts). Mine were PAE mounts bought around '97 and I had a Hell of a time tweaking my mounts to fit on the pads. Everyone at least at that time was just copying the original 67 mounts. That may/may not be the case today.

Plus, the TA mounts give you the option to set the engine back for better exhaust fit with stage 1 heads (and slightly better weight distribution). The TA's are aluminum, so you can save a couple pounds if you're looking for that last .001. I would suggest you go stage 2, the purpose-made TA headers fit wonderful.

 

I used the PAE frame mounts in my 66 (bought them a few years ago from Poston). They worked great with no problems. Just the standard motor mounts. I didn't need the 67 passenger side mount.

 

Well Jim is certainly available for a clarification. Maybe I had a motormount problem (made in India)

 

I've got a used pair of 67 GS frame pads for a BBB. $60 shipped. Bought them for a g-body but they didn't work out.

 

Dave - what did you mean: "I didn't need the 67 passenger side mount."??

The factory 67 GS400 had a special passenger side mount that is no longer available. Some of the early repro frame mounts were direct copies of the original and so one either had to find a good used 67 mount or cut-and-try.

The TA mounts correct this by using the standard available mount, and apparently the newer PAE ones too?

 

so what mounts do i need for my 67 gs400 i have the factory frame mount im gonna put a 75 455 in it

 

Like Adam said, the 67 and some early 68 GS400's had a special mount on the passanger side. The early passanger side mounts are no longer available. The only options if you want to keep the original frame pad are to find a n.o.s. mount or get a used one revulcanized.

 

My 67 GS 400 had a broken rubber mount on the drivers side and there are no new ones. I ordered conversion mounts and realised my air cleaner would go into the hood if I used the 68- up mounts.
I went back to the stock stuff and took the broken pad to a machine shop. I asked him to drill 4 holes through, cut 4 steel rods, insert and weld the rods on both sides in the holes.
I have stock rubber on the passenger side, stock but welded on the drivers side, and my hood will close without hitting the air cleaner, and no longer need a log chain to hold my engine down.

It's a damed shame you can't buy stock demension interlocking motor mounts for a 67. But how many other parts are available for 67's, like a new grille!

 

I used the TA mounts/pads and maybe I got a bad pair but they were a mess. I had to grind material off the pads to get the mounts to fit over them and I had to re-drill all but one hole on the pass side pad to get it to fit.

Once I got the motor in it sat too high to fit a drop base aircleaner with a 3" element and a 17" fan would not clear the repro GS400 fan shroud. Problem is, if it sat any lower the TA 1 7/8 headers wouldn't fit. It also threw the pinion angle off so now I may have to buy adjustable upper trailing arms.

I think other people have had better luck than me but if I ever have to pull this motor they're going in the trash. Hopefully by then someone will make frame pads to set the motor in the stock location and also headers made for 66-67 not 70-72. Yeah right

 

Here are my TA mounts. I use a mock block and tranny case. I had to pound in the motor mount bolt on the passenger side in mock up but I think if I left the mounts loose until the engine was in I would not have a problem. I did have to ding the headers on the passenger side only for my 64.

Bob I have my pads bolted to move the engine back some and I see yours are in the foward holes.

 

I think you had a problem with the frame holes, even my 64 had the right holes to bolt the mounts. As I understand, you have the option of setting the engine back, or using the holes for the stock location.

I had to bend, shim, and tweak my fan shroud to fit too. I think it's the shroud that's not too good. I got it to work, but not without a lot of bitching at it. It must be hard to mold fiberglass for something like that.

There's only one drop-base that'll work in this application, it is the repro Big block chevy one sold in Year 1 for $4x.00 . The regular parts store ones don't drop as much. Trust me, I looked high and low.

Ed is right, no matter what you do, the stage 1 headers were made to fit the 8-72 chassis and don't fi our earlier cars perfectly. dents, gringinf of the chassis, I even notched the frame. TA makes stage 2 headers for this application that fit PERFECT.

Don't blame the pinion angle problem on the mounts, I think they only change the height by 1/8".

Ain't hot rod building fun? :rant:

 

I believe somebody a long time ago somewhere said the frame mount could be modified to work with the later mounts, but it involves some heavy grinding on the pad and maybe redrilling the bolt hole in either the pad or the mount?

 

The height comes from having to use 68-up motor mounts.
WE NEED GOOD PADS AND 1967...I SAID 67.. MOTOR MOUNTS. goooood interlocking 67 motor mounts sombody please

This combo would serve all 64-67 A bodies with stock hood, aircleaners, shrouds, etc

 

Gary,
Are/were the 67 mounts thinner? Are you sure the TA frame-mounts didn't compensate for the difference? (I have no idea, but hope they would think of that)

 

d-con

I had a full kit and measured, and measured and tried installing it and verified the height problems and finally said NO WAY.
The motor mounts are for sure thicker on 68-up . I can't remember about the frame pads but they may be a hair thicker.The total height was too much for all the trouble.
Micky Thompson headers fit stock height but took some denting for the steering and right a-frame. Not too bad.
I went back to iron 67 manifolds after rust ruined my headers.

Your tall motor mounts would likely add less than one degree nose down pinion angle.

 

i may look into making some replacement solid mounts in the same 67 specs. if the interest is high enough. now where did i put my stock mounts???

 

Talk to HR Parts N Stuff. They do polyurethane mounts for Gn's, and might be willing to fill this niche market.
