Automatic or manual transmission and are you going to move the crossmember? Some guys converted from a six to a v8 and use the original mounting of the six. Others move the engine to the front mounting position. Other variable may be the towers -V8 or six. You can also try a small body HEI that fits in there and give you a little more clearance.

One thing I am thinking of doing on my 69, if I ever find a cab for it, is to move the towers between the front and rear mount position and redrill the holes. It will give me a slightly better center of gravity and won't affect the drive shaft.

68gmsee · 08-24-2013, 05:14 PM

Oh, oh, just saw the last photo. I guess you're stuck with location unless you grind the weld and reset or get the proper towers.

Previous owner gobbed the welds up.. just wondering if he moved bit back too far... or where they are supposed to be

Looks like they welded the engine stands to the frame?? Supposed to be bolted down. Was the truck originally a 6 cyl? Looks to me like its sitting in the 6 cyl position.

Redleg87 · 08-24-2013, 05:14 PM

Its manual. I see it uses the rear two of the three bolt holes.. just doesn't seem like much clearance between firewall... what do u think?

My 68 was originally an I6. Years ago, when it was changed to an 8, they used the rear two mounting holes which is the original location for a 6. An 8 will work (as far as location goes) in the rear holes. However, with that said, the original location for an 8 Was in the two forward holes on the frame.
As previously mentioned, it will matter which trans youre going to use. In my case, I switched from an auto to a car 4 speed and had to relocate the trans crossmember anyway--so I wasnt worried about where the crossmember was originally.

Those are not 67-72 mounts at all. They're 73-87 mounts.

Hold up a minute.

What's the problem ? You're seeing that ugly weld there on the front edge of the mount, but notice those two real fat plug welds where the holes used to be in the mounts ? That thing isn't going to come off without a real fight. Why are you worrying about it ? Is the engine touching the firewall anywhere ? Close is fine.

^ I agree with above. Don't go overboard, that's why I mentioned on my post above a small body HEI would give more clearance.

Redleg87 · 08-25-2013, 12:55 PM

Nah its not touching. About an inch from valve cover and dizzy still turns freely.. I guess I'll just grind those welds off and re weld.

Right?
Thanks again guys.

I just put a 383 in my 70. There are two sets of mount positions. The previous 350 was in the back position. Moved the 383 to the front and it is much better IMHO.

Much better as in having room to work? What about handling.. with the engine being back a little further will the weight off the front help?

TacBlade · 08-25-2013, 01:25 PM

More room to work and handles great. I have sway bars front & back and a 1"/3" drop.

Redleg87 · 08-25-2013, 02:26 PM

First I was worried about it maybe hitting if say the motor was too close.. now I guess since its ok.. are their any pros/cons

How are your cab mounts ? A set of fresh cab mounts makes a difference in clearance too. I've run small block with HEI back real close to the firewall a good number of times. Other than having to reach further back the access the engine when working on it, no down sides.
