Thanks for the info guys. Are there any advantages for going with a carb vs EFI?? Was kinda hoping to stay "old school" here, keeping it simpler. I've heard horror stories about "add-on" power adders (ie- NOS, superchargers, turbo), so I'm concerned to go down one of those roads. I've read about some BIG small blocks, 440 & 460, from a 351 block!!! Any info on those, price, performance??? Thanks for taking the time to answer!!! Oh, and this is a 6 cyl car now, so I plan on "beefing-up" several things like front susp, brakes, steering, tranny, rearend, etc.... It's a beautiful car, but is it going to be worth it?? I hope so!!! Thanks again!!!
