Look into 4.3 Elky's for a possible source for the fuel tank/pump.
Thanks, I will. There's a junkyard close to my school that has 4.3 Monte sitting in it. Maybe I can cop that one if it's good, or I'll just get something brand new online. I think I'd rather have something new
 
Gotta remember the coupe/sedan tanks are different than the trucks. This would include the sender/pump.
Ahh, i didn't know that, thanks man
 
Why do you want to go EFI? A correctly setup Qjet, especially a computer Qjet will give you EFI MPGs. No fuel system can counteract a lead foot. TBI has less flow than a Qjet, the best factory TBI are the 9C1 (Police) versions.

Those self learning kits can take months to fully self learn. They are also designed for mild performance powertrains, not bone stock low performance base powertrains with the gearing you have. In fact they can not respond right if your engine makes too much vacuum.

I'll look into the TBI, thanks. I figure the EFI can easily be transferred to a more powerful small block if I got rid of the 305. Just trying to plan ahead
 
2.56 gear could be part of your problem coupled with the low torque 305, you're having to push it harder to get to where you in it's power band.
i think you're right. I talked to a shop about getting 3.42s but the price came out too high, I think I'm going to wait for now
