Frisco that frame dosent scare me half as much as seeing a straight axle with a big block up front no thanks and as for the drawing of the orginal post, i think the part you over looked is the fact that if you hit something head on you just created the huge bending point in your frame not safe!

I do not want to box the frame because I will use the stock suspension. The original frame was made to flex some with the movement of the suspension. I don't want to change that. I do remember that I was going to have to trim the front crossmember a little for the crank pulleys but not as much as your current setup. I think the crux of your problem is the big block and its larger size. I will take pictures of the current mounts tomorrow and hopefully it will help.

I think the damper should be ok. The pully isn't on, but I held it in place and it should be good, even with the belt. It's tight, but I think that if the motor tries to torque in any direction it would be right to left and up. I'd sure like to see your mounts. Your comment about the frame flexing a little with the suspension was something I hadn't thought of. It's the only argument against boxing I've heard.

The front suspension is all brand new. I had new springs built. Also I have brackets for Monroe gas truck shocks. Remember I'm not putting the first V8 in this truck. It had another 396 in it all through the 80's. I'd like to eventually put in either a Buick 455 or maybe a 327 if I want to tone it down some.

I think you have me confused with the author of this thread.

It is not my frame; I just offered my thoughts.

As to the big block with a straight axle; that is not a problem at all. The problem is how best to strengthen the frame where it has been altered.

The drawing is not mine; but was done very well by the author of this thread. You are correct about what would happen to this frame as it currently is if involved in a "head-on".

I found some old pictures of my setup. Hopefully they will come up, I am new at this computer stuff. Look for the 2 attachments. Once again I am going to remove this setup and put in a tubular crossmember to stiffen the frame a bit. I believe boxing the frame with the stock suspension will create stress points and future cracking. Hope this helps, and the balancer is 6 3/4 inches in diameter.
