427 In a 67-72
As some of you know i was going to buy a 427 tall deck and fix it all up but then one I found was stolen from underneath me, but now that I have a good job I can afford a regular 427, I wanted to know if any of you guys have a 427 in your truck, just the old "car" 427, and what all do I need to put it in there, I know mounts and stuff like that but any tips I can get is helpful, what kind of headers, what heads, any special crossmembers I'll end to find, special driveshaft, or anything that I might not think of, I'd appreciate it, and what kind of manual transmission stands up the best behind this motor

Re: 427 In a 67-72
As above, as far as mounting/exhaust/oil pan/intake(there are oval and square ports), distributor/accessories/bellhousing a "regular" 427 is the same as a 396/402/454. Heads, cam, and intake depend largely on what you intend to do with it. Do you want to drag race, cruise, haul/tow, etc. There are some good factory heads and some awful ones. I would want a roller cam given todays cam materials and oil issues.
But if you don't have any of it, why would you want one? If you have one, I can see keeping it. But if you don't have one already you have to buy exhaust, expensiver mounts, they are heavy, they are harder to cool, they break starter noses, they drink fuel. For the same money, buy an LS and have the horsepower, torque, and add fuel economy and startability. With all the ethenol in todays fuels, it is harder and harder to keep carburetors going-the fuel just eats them up. Yes, a big-block looks cool-but do you just want to look at it or do you want to drive it? My .02

I have a 67 vette 427 in my 72 GMC. It mounts just like any other big block would.

Re: 427 In a 67-72
The big block conversion topic is so beaten to death that someone should write a guide and post it as a sticky.
I say someone rather than "I" because mine's a big block and have never converted it. Cars I've converted may not inform all the issues for these trucks, particularly once you get into the K trucks (which did not have a factory equivalent big block setup).
