Some of you may remember me from earlier this year when I was learning about and trying to sell a supposed 79 highboy. Turned out it wasn't a 79, it's a 77, and to the point of this thread, the 460 it has isn't the original motor. It was originally a 351M with a C6, which looks original.

Well I wound up buying it myself, and its AWESOME!!!!!, but it has some issues. The motor mounts are homemade and the motor is crooked and seems to be setting high. I want OEM style mounts.

What all do I need? Mounts for sure, engine brackets for sure, but do I need different frame brackets?

Another issue is it seems to run hot, (not sure yet, I'm gonna put mechanical gauges in it this weekend). It has an absolutely HUGE radiator in it, 3 core, good shape and I had to cut the rad support to uncover about 4 inches on the left side. This thing weighs 65lbs dry. The rad didn't fit right when I got the truck and I had to do a fair bit of work to get it mated to the support.

What radiator and support combination do I have? The support looks like it might be light duty and the rad is HEAVY DUTY!. Sorry for this question, but since it doesn't have a shroud, which one should I look for?

And the last issue for now, the power steering cylinder connected to the drag link in front of the axle is leaking like a seive.

Is it repairable, how easy is it to do and where would I get repair kits if available?

Thanks in advance, this has been an excellent site for me in the past.

 

Here is some 460 swap mounts for that application (these are much tougher then the L&L mounts) and they look very close to an original mount.
