Any headers for a SBC in a Gbody should fit fine. Lots of header kits for '64-'72 Chevelle share Gbody part numbers too so they should be pretty close.

Are you sure about this?
I bought an Airtex Pump from Summit a couple months ago that I have yet to install. If this is true, I'll return it and get a pump/sending unit from a truck.
Wouldn't the sending unit/pump from the truck be too tall? Isn't the truck's gas tank deeper from top to bottom than my G body Regal's?
Youll be good with a sender from a donor car either GN or 4.3 monte, or you can purchase new, as far as the pump I do beleive that the truck one is the same size pump as a cars pump as long as its HP EFI. Im doing a similar build for a friend, but its a LT1 motor. I donated him all the lines and my sending unit from my GN. Ive done quite a few of these swaps and plan on putting my L31 into my vette sometime in the summer and junk my z71.
Best of luck with your build, let me know if you need any info.

Ok, let me get some clarification...
The truck in-tank sending unit has the fuel pump on it, right?
Does the sending unit from either a GN or 4.3L Monte have the fuel pump on it?
If the truck sending unit/pump is the same size I'd rather go with that way because it would be application specific as far as the engine is concerned, i.e. psi, flow rate, etc.
The truck sending unit will not fit a g body tank, only the fuel pump will fit if you use a sending unit from a fuel injected gbody such as a GN or EFI 4.3 monte. You can purchase the tank with the unit used from the junk yard, or get a new sending unit from a vendor, and install it into your current tank. The benefits to getting a tank from a junk yard is that those tanks had internal baffles as the aftermarket doesnt offer them, at least I havent found them.

Ok, so I could take the fuel pump off of the truck sending unit and install it on a sending unit from a fuel injected g body?
I didn't know that the fuel pump could be removed and interchanged like that.
I don't have the fuel pump or sending unit from the donor vehicle, is it wise to get one used?
And how hard is it to "fit" the fuel pump on the fuel injected g body sending unit?
The pump outer dimensions are the same its not hard to change out and you should go with a brand new one but its strictly up to you whether you want a used one to go bad and have to do it all again. Racetronix, builds a really nice sender with the pump already on in Stainless steel or regular for a decent price. I also found that gbodyparts has a new baffled tank in case you decide to go new, maybe they have the sending unit too.
You saying I should go with a brand new pump or brand new sending unit?RUDE DOG said:
Is this the Racetronix one that you're talking about?

That's a decent price? Along w/ the harness they say you need, it comes to $239
No new tank for me now, I bought a new one a few years back from www.gastanks.com. Unless it has started to rust & corrode from the inside from sitting for 6 years (dang time flies), I'm gonna stick w/ it and get my money's worth.
Thats the one, I also think its a good price for a stainless unit with pump installed. The tank should be good like you stated if it doesnt have rust, if it does have rust then you can always use some metal rescue and it should take care of any rust the tank might have.
