thanks guys, yah I do all my own fabing, since I was a kid I always had the dream of welding things together, then finally It happened, took some schooling to learn a little, but don't do it for a living, just for hobbies. Currently I'm starting to build a second hf tig welder out of parts from a industrial junk yard, building welders is kinda a second hobby. I know what you mean about the carb thing, I really dont have to much time to learn about tunning EFI right now, I only get to the track once a month 5 times a year, this car is more of a max effort drag car so I felt I could get it tuned faster with something I understand a little more. There s a lot of benifits to efi, my other ls motor has it and i did learn some stuff about it so I 'm not in the dark with it, there was a deal I coundnt refuse on the blow thru set up, so thats why the car is getting it. I do have plans in the future to go EFI, just not now, not this far in the build.
