451Cuda, just put your manual valve body in and live life happy. It's time for this to move on, the bickering will not advance newbies, or interest, or impress staff members. I seriously doubt with the cost of the cuda, 440 and tranny, manual valve body, exhaust, rear end, that no matter your E.T., your cost will be too high to be competitive. The vehicle I'm thinking on entering cost me 800.00 bucks. I hope not to put no more than 200 in upgrades. Total cost, I'm hoping, is to be right at 1k. Will it run with a big block cuda????? For your sake, I hope not!!!! LOL ! However, in a race of cheap, simple, street driver, and did I say CHEAP? I bet I take your big block cuda right out of this competition..... :D Let's line 'em up...... at the cash register!!!!! :D
