[mr340]

I would fall into the "grew up with these cars" category. I think you have a really nice car there, and 340 or 383 doesn't matter to me, it is after all your car. I just think you should sit back and look at the big picture, take some of the older guys advice, and don't get in over your head. That 340 will get you into the 13's, probably at the same cost as building a 383. you just need to find the right combination of equipment and weight reduction. If having a big block dart is your goal, go for it, but again listen to the advice of the guys that have "been there, done that".
