    Default Planning an engine build... have questions

    Trying to build an Explorer motor over the winter for my 87 Tbird.
    I picked up a new in box b303 cam( I know there are better cams but it was cheap)... Can I run 19lb injectors? I have a set of GT40 -3 bar heads with a TF spring kit installed. Also what computer should I pick up as I will be switching to MAF. 5 speed swap as well. Can I run stock length push rods?

    I don't have any experience with the B cam, but GT40 heads with a Ford cam should be able to use stock pushrods. I used them with an HO cam and stock rockers.

    Ford computers, as far as I've seen, are no longer being reman'ed, so people are charging an arm and a leg for them. A9L would be the one you want though. You might want to consider going to an aftermarket computer like an MS2 or even a full SEFI control pack. Holley just came out with one for decent money. I went with a Ford computer myself, and am kind of regretting how much I had to spend for 30 year old technology.

    19lbs/hr injectors are fine for up to about 300hp. Your engine will definitely be less than that.
