New to the forum and new k20

[jtge]

Hi, I'm new to the forum. I just bought a 1967 k20 pickup truck. It has a dying 6 cyl engine. Cylinder compression are between 50 and 70 psi on all cylinders. I'm debating between overhauling the engine, or replacing it with a newer 8 cyl 350. If going the 8 cyl route, will the gearbox/transfer case will be easy to adapt?, or should I keep the I6 and do the overhaul?.

Thanks for the help.

It should be a simple bellhousing swap. Can you post pics of the truck.

I swapped out the 250 for a 350 in my 72 K10, and it dropped right in, bellhousing and all. And let's see some pics :-)

Thanks for the help. Which 350 model was the one that fit right in? Carburatted or tbi?

Bellhousing pattern is the same on 350's, so no concern there.

Try to buy a complete engine with pulleys, brackets, etc.

I used a mid 70's 350
