Madmaxx, Humbucker is spot on. A change in heads is a big plus. Ford Racing makes a new 392 that puts out 475HP. Look under racepartsdistrubition.com and pull up Ford crate engines. The big change in this motor compared to the 430HP version is swapping to Z304 heads as opposed to the X303-GT40 heads. I run a Victor JR on mine which performs pretty good. The reason I haven't upgraded mine to AFR 185 heads is my pistons are the old style cast ones and I don't want to put big money in my engine. There's nothing wrong with cast, but if I'm going to go balls out, I'll start out with everything forged on the bottom end. I'm looking at a Roush 427 (Dart 4 bolt) engine with 2K miles that's been rolled in a totaled out Mustang. Hope to get a good deal on it? But you never know. I changed out heads /intake on my last Cobra and gained 105 HP. And like Jake says, it's a totally different drive afterwards
Hope this helps
