engine swapping 350-454

[Tim]

what all is required...other then the motor? say late 80s burb or k 20?

It should bolt in place of the smallblock. You will need all of the accessories from the Bigblock. You may have to move the motor mounts on the frame a bit (there will be holes for this in the frame). The SB use the top holes and the BB's use the lower holes (If memory serves). You will also need the larger BB friendly radiator and may need to add a spring or two to the front springs to level it back out due to the weight differences between the two engine's (750 for the avg SB 1000/1200 for the BB).

You seem hellbent on a big block, but you can build a 350 that runs strong and is very reliable, and even be more efficient.  I know big blocks are cool, but something to think about.  It takes a lot of gas to go to Utah in anything, much less something that gets 4-7 mpgs......

They say the 96 97 98 Vortec 350 is best small block ever built.   

I love the one in my Yukon.

The mecca of all things GM SFA trucks.  If you have a question on a 73-87(91) body style GM truck than that's the place.  Anything you can come up with someone on there has done 4 times and knows 6 different ways to do it.  Meanwhile there's always someone doing something completely different with it.
