Re: '76 350 into an '85 3/4 ton 4x4

Well, it's time to do the swap. I have the 76 engine on the stand and hope to use the original cast intake with the original Quadra Jet carb (will rebuild). I plan to replace the water pump and fuel pump, but have not closely compared the two truck's pumps....

Should I buy the replacement pumps for the 85?

The 76 did not have a return line on the fuel pump and I think the 85 does. I am assuming that both the 85 style pumps will bolt up to the 76 motor.
