    If it is going into a non-EFI tank, I would suggest the newer style fuel pump module. Like here:

    Pretty easy, cheap, and will support lots of power.

    Haha, the caddy 500. I have one of those in the storage shed, disassembled, in need of a rebuild. I have plans to one day build it and swap it into my cherokee, but money has kept me from doing that. Plus my current 401 is only a few years old on a full rebuild, so I will probably wait untill I wear it out. So I may be 50 by the time I swap it in (I'm 29 right now)...lol

    I remember a build on one of those several years ago in a hot rod mag, they built it and it had more HP, an just as much torque as the customers duramax diesel. I think I still have that issue somewhere....

    Those big caddy motors have always been huge tourque monsters! Pushing a 6000 brick down the highway at 70 MPH effortlsly, just touch the gas and 100 MPH comes around. Of course gas was a lot cheaper then, but that was not even a point to a Caddy owner!

    I hope we still have gas by the time your 50! But there's enough scrap metal there to build a new car...

    Today while at Pull&Save, we found a '74 Eldorado, with a 500 and FWD TH425. My dad and I want to take the front half of the frame from one and graft it the back of the front half of a Datsun pickup. So we would have a rear engine pickup. And of course EFI it.

    Now that would be cool!

    Next time you go to pull and save let me know if you have room for one more, if not my wagon will seat 6 and still carry all the parts back!
