Hello Sun520,
I am in the middle of setting a L20B in my 66 520. What I am wondering is 2 things, the auto trans and the clearance of the radiator and firewall with the motor.
First do you like th automatic? Does the truck have enough power? Still Cruise down the highway well? And what transmission is it if you do like it.
Second did the firewall or the radiator have to be modified to get the motor in. Does the water pump still have the fan attached or are you running electric fans? How are the motor and trans mounts adapted?
I will be posting pictures as we move through my conversion.
Some pictures would be helpfull.

If you can not post your pictures here please email me some.
Thank you,Charlie
