Yeah Seth I cant remeber how they explained it to me at LC
Ok so here another problem youll run into the 22r and 22re use a rubber gasket for the thermostat,you have to go back to the 20r thermostat gasket.
Next when you have to install the senors you wont be able to run a factory fuel pump and youll need adapters so the sensors will fit.
And Finally a big block chevy fuel pump block off plate works wonders here....it 4.99 and works as good as the LC 49.99 plate
