Suggestions welcomed

Build A 500HP Capable 360 Magnum Short-Block On The Cheap! - Hot Rod Network. These guys at IMM are about an hour East from where I live and this build sounds about as good as I've found for what I'm looking for out of the car. The car was originally a slant 6 225, so I'm guessing there's not a lot of heavy duty anything from the drive shaft on back. Haven't pulled the numbers off the differential yet, but I'm going to soon. The 360 I have in there currently is a 79' block with a Holley 770 avenger carb, a Weiand 7510 intake manifold, the exhaust manifolds came off a 340, no headers but duel exhaust with an H pipe and turn down exhaust. It definitely has a cam that has the classic rough idle, but I don't know the specs yet. The 904 is a 75' and has supposedly been rebuilt recently. In short the car is fun as is but definitely has more bark than bite as far as performance goes. I'm definitely grateful for what I've got, but like so many of us, I need a little more punch lol! I appreciate you guys so much on this site for sharing your time and experience with a newbie like myself! The one thing I can tell you is I've been obsessed with Mopars since my first one ( 71' Challenger) I bought as a kid in 1987. Since then I've owned all A bodies: 69' Dart, 72' Dart Swinger, 73' Duster, 74' Dart Swinger and also a 76' Scamp. I'm thrilled to have my 71' and actually hang on to it this time as my life finally settled down about 6 years ago.... Thanks guys
