UPdate

Here are some OLD threads about caddy's in our trucks. First two are the main ones.

You are correct about the pan and towers.

As for parts available at local part stores, good luck. They are expensive motors, but you don't need a lot to get more power. As for a cam, that's what a lot of people do for easy power, but it's not that much. My motor is all stock except an aluminum intake and an 850 double pump holley and I'm getting enough power to get my longbed stock truck down the track in low 12's. As for drive-ability for street use, I'd recommend sticking with a 650. Small carb yes, won't get all the power out, but better on gas and still have plenty of get up and go when you want it. 429's are the same way minus a ton of power in both hp and torque, but with a bigger carb and a cam, you can get a lot more power.

As for putting a caddy motor in a way older vehicle than a 69 c10, it's very doable. My grandpa was a fan of putting caddy motors in everything including 20' - 90's cars and trucks whether it be ford, chevy, or dodge.
