|against all odds||i feel that a big block can be procured for under $2000 and after factoring in the extra mounts, brackets, time etc. for the BOP engines i think the savings will be even more.|

If you really are into bop and want to go that way, then by all means proceed.
i'm just looking at it from a practicality standpoint; A big-block chevy can be found just as cheap if not cheaper than bop 455's.

|bwconnell||I am also in the process of a frame-up restoration of another 85 chevy k20. It has a 12 inch suspension lift w/ 42s. Thinking about a 5.9 cummins for this one. Any ideas or thoughts? Also, thanks for all the thoughts on the 400 project.|

Good tips btw, good to have some that knows Poncho motors helping out in the thread.

Putting a 472 or 500 cad motor in it would also give good results, if you had one of course.
Having a K 10 or K 20 with big tires , like 44s and trying to drag it around with a whimpy SBC just dont get it. The torque of the pontiac or caddy motor would do very well.
The pontiac makes good sense. Lots of money is spent on stroking the 350 to a 3.75 inch stroke , for more torque of course. The pontiac is allready there. Even though the pontiac is more expensive to build...
I also think the firebird mounts would be the way to go, just be sure your block has the front pads for the mounts as the 3 pads to the rearward posisiton are for the A and B body cars.

"Speaking of mounts, I used the stock Chevy mounts with the Firebird's brackets. It fit like a glove."

I have entertained thoughts of putting a pontiac motor in a chevy truck also.
Hey... they did it from the factory in 1958.
And , like was said, big power for plowing, pulling trailers etc.
I totally like the Idea, I will be watching this thread.

the 400 I have is in great condition and will be used for snowplowing and towing.
Also got a good deal on the moter. Anyone know the site to get the swap motor mounts?

I know why we did it to that truck back in the seventies, it was a no brainer. This truck pulled a 5 horse fifth-wheel trailer. They had a steep driveway that they literally couldn't drive out of with the trailer full, the 350 couldn't do it. They wanted a big block and the big blocks were BIG money. We bought the guaranteed Buick 455 with the TH400 for something like $500. If the 400 is owned already and in good running order it will pull circles around a small block.

|Valkyrie5.7||I can see where you're going but in this case to me those seem like small inconveniences. There's really no replacement for displacement and when we're talking making a full size truck go fast, it's probably going to take deep wallets or more than 350 cubes.|

Well, the reason why i personally would stick with chevy is:
1) It will be much quicker than using an engine that was not originally installed in this chassis; i can install a SBC in a car that originally had one in about 4 hours. It would probably take much longer with, for example, a pontiac v-8 because you would have to hunt down the mounts. The alternator and starter are on opposite sides, so now you got to extend the wires. Yes, i know, not a big deal but it will take more time. Then we got to deal with the trans adapter.
2) It will be cheaper in that we don't have to worry about obtaining the extra parts needed. I.e., different mounts, adapters, hardware etc.

Why wouldn't you want to do this? You can find a lot of factory 400+ cube BOP motors that came ready to rock from the factory. Since we live in this "chevy-centric" world where everything gets swapped for various generations of the SBC, the other brands v8 mills can be found inexpensive because most people think that 350's are the be-all, end-all of performance motors.
