Mounting a Chevy BB question ?
Post by elohim1 on Aug 3, 2006, 7:57pm

I am aware of using plates like Spicer gear made to adapt to the stock motor mounts.

Is there a better way?

I am using the 502/502 engine.

If you have pics please post them.

chris, you can mount it like the drag guys do. 4 points. you can make an alum. or steel engine plare for the bellhousing area and same with front of engine. this way its totally captivated . then use poly mounts to chassis. you can pull the trans and engine stays put too.

Some members have mounted BBC engines in the trucks with 66-71 Chevy truck motor mounts. They look just like the stock 230 mounts and fit right into the frame horns. You will have to dimple your passenger side firewall a little to clear the valve cover though.

I am not all that positive on the years given above. I know for a fact that 1966 Chevy trucks had that style. The member I am thinking about BS isn't around anymore and I think he said his were for a vehicle in the early 70's. So, go to the parts store and have them pull up pictures of the mount before you buy it. It will be a rubber block with the triangle 3 bolt plate to the block and the threaded stud to go in the frame horn.

I used the "Spicer plate" on my big block because I didn't want to mess with changing the short shaft between the transmission and t-case. I made the plates as big as I could, left the stock 230 mounts in the frame and then set the engine on top of them. Once I had the short shaft hooked up and the transmission mount made. I just marked where on the plates the holes needed to be. I picked up the engine a few inches, removed the plates, drilled the holes, taped them and then put them back on the engine to bolt everything up. I went back after I got it running and driving and was happy with it to remove the plates and cut off the excess.

Like everything else with these trucks. You will find about 10 different people who did the same basic thing 10 different ways. I personally like the "cut off the frame horns, make arms that come off the engine motor mount pads, drill holes in the top of the frame and bolt it in with a rubber bushing between." I had to do my swap over one weekend though and didn't have the time to make all that work. Find a way that works best for you and do it. Remember, short shaft, valve cover clearance and fan clearance for the radiator all are affected by how far forward or rearward you mount the engine.

Chris,
If you don't have any mounts, here's the transdapt version, I modified them to make them more like the AA versions with a gusset plate... they are welded to bare frame, i'm planning on tieing them to the shock mounts on the outside of frame for more structural suppport...

Their website sucks. As does their catalog. Phone support is pretty good most days.

Their catalog ROCKS!

it's just a little confusing at first.

if all you need is part numbers, or to cross reference application to part numbers then yes I'm POSITIVE it rocks.

but if you need to SEE what is included or what parts LOOK like, then it sucks... Or maybe they've redone it since I last looked.

somebody needs welding classes!!!!!!!!

Bob You can see. I noticed that too, maybe just more practice. You can't weld beautiful all the time, I know I don't. I figure he was just trying to keep with factoy weld look. These trucks hardly have a pretty weld on them.

Chris,
I used the "any SBC into a J-series" from transdapt, then added the diagonal support...they fit perfect for the BBC

Bob,
don't start throwing rocks...
here's one of "your" welds

he's an exceptional welder, doesn't show in the pics...like Fisherman said, the welds are far better than all the factory stuff on the truck...remember pretty welds aren't always strong welds...penetration is more important than looks.

I think I like this setup Barman suggested. I was considering using 3" channel and cutting an angle on it then welding a mounting plate. However, I am afraid it will look "ragtag". Is there anyone out there that makes the setup Barrman is speaking of ??

uhhh... Yeah... Maybe I'm missing something here, but that sounds EXACTLY like what the transdapt and AA mounts do. They're dirt simple, but for the money, I would probably just buy them to make sure they are spot-on.

What I was talking about is what AA does. Novak has the kit that uses the stock 230 style motor mounts and requires some firewall "clearance" with a BFH. The Transdapt and AA mounts require the stock frame horns to be cut off.

As I stated in my first post, I like the "arm" style but only had 2 days to do a complete "230/T98 out, 396/NV4500 in" swap and went the safest/fastest way with the "Spicer plates."

Now i see, I thought you were talking about removing the horns and setting mounts off the motor directly on top the boxed frame with out having to weld perches.

I will go with AA or Transdapt then.

Is either one of these stronger ?

That is kind of what I was talking about.

Cut off the stock motor mount frame horns.

Buy a kit that includes new mounts that come off the engine toward each frame rail and then mounts to a perch you weld on the frame rail. This is really the best way to clear the stock steering shaft unless you are doing a body lift as well. Then the steering is above all of this and not a problem.

Or, make the same as typed above for a lot less.

Or, mount the arms directly on the frame rail. This will work, but the steering shaft kind of gets in the way unless you do a body lift.

I have seen each of the above options in trucks. It really just depends on how much fabrication you want to do, time and your skills.
