    I have a big block in my sea boat that is currently carbed, I am looking for better fuel economy and tuneability from it so I am converting it to run with the LS1 computer, stage 1 is to modify the distributer to take the LS2 cam sprocket with with sensor. :big_smile:

    I am ordering a new intake manifoid for fuel injection and new throttle body, I will run LS3 injectors, it will look like a carb set up but will be injected :big_smile:

    Cool looking manifold. Reckon you could have got away without using the cam sensor?

    Yeah Thought about it but I need to use a distributor for the oil pump so might as well fit the sensor to it :big_smile:
