Well it seems to work for you. Carbs are still evil voodoo to me. I could never get what I wanted out of mine and gave up to go with a TBI efi setup. So the idea of abandoning great efi on an LS/Hemi seems like a waste.
I have done quite a bit of tuning with both EFI and carbs. I've done all my own tuning on my SS and on friends cars. I enjoy the challenge and learning experience of the EFI. From tunercats obd1 (dos based stuff) to the HP tuners software we've been working with lately, and also some FAST EZ EFI stuff on dads truck.
The valiant might eventually have EFI as well. My main reason for going carbed on the valiant was because I already had a big HP fuel system with cell, 8 AN line, and big magnafuel pump. Than I found a smokin deal on a carb and intake. I have little to nothing into going carb.
Currently I am getting 14-15 mpg with the valiant with a 4.10 gear, 31" tire, 4000 stall, and a 950 hp carb. I don't even have the MAP sensor hooked up yet or an overdrive. I'm pretty happy with it. I think it's a good compromise.
The distributor conversion thing though, I really don't get my self. Unless your trying to turn 8000 + RPM. Eric L
