Backhalving?
I don't have anything against tubbed cars. I've built and raced two myself.
I do have something against recommending very expensive mods when they may or may not be needed.
Is he planning to do fast brackets, or just have a cool street car? Will it be a trans brake? (probably not)
Does he even have a built motor in his car yet? Is there even a 440 in the car right now? I guess we need more info from 440valiant.
Is he limited in funds? Maybe he works part time and is in school? I don't know.
Is he ready to have his car be completely down and disassembled for months and years (I see your thread started 1/07) before it's driveable again? If you don't have at least 5 grand sitting in the bank right now to buy all your parts, it will be. For a LONG time. Thats all I want to get across, is that you can run low 10s EASILY without back half. Is that so hard to understand?
I'm done here. If he wants it, he should go for it but i've made my case in spades.
