Got the big block in my '72 K5

[AK|Bandit]

Getting ready to fit the engine for clearance


Engine centered over the motor mounts


Driver's side firewall before the beating


...and after


I notched a little piece of the frame to add clearance to the PS pump and pulley...It cleared okay before I notched it, but I figured what the heck.


The distributor cleared fine without any beating...thanks to the 3in body lift.


Oil pan clearance wasnt even an issue with the stock crossmember. I used the small block mounts.




And this is how it sits right now...


After I fit the engine for clearance, I attached the tranny and slid it in as one piece. This made for a very easy install.
I still have to fit the headers in, but it looks pretty tight I'll update when I get them in...if they fit...
The passenger side firewall required minimal "massaging" to fit the valve cover.
I cant wait to fire this bad boy up!

Yep you sure can. I went to the local parts store here and asked for '72 K5 motor mounts for a small block 350. They were only about $25 for both sides and they fit without any modification. Bolt holes lined right up.

I'm pretty sure the whole bb motor mounts thing is for 2wds. 2wd BBC swappers have hassles with either using scarce, expensive eng xmember towers with inexpensive motor mounts, or using plentiful eng xmember towers with expensive motor mounts. That's my understanding from perusing the board, anyway.
