Reply to "AFD Alum heads"

Hello Kevin,
Welcome aboard. You've come to the right place for Pantera/Cleveland help. I have a set of the AFDs 2V heads. It's a good news, bad news situation. I could probably go on for pages here but I'll sum it up without thinking this through. It's going to cost a lot more than you're planning on when it's all said and done. I went with the AFDs with the intent on using a lot of my same stuff like intake and headers. The recommendation was to go with the Offy intake as it would fit under the stock screen, which I wanted to use. The intake needed a lot of work to match, beyond the normal port matching. It turns out, and I didn't know it at the time, that the heads came with a couple of spacers that go underneath the intake to raise it up. My heads were wrapped with some bubble wrap and were thrown in a box so they could bounce around. They were damaged but it took so long to get them I was glad they finally came. The box was damaged so I lost some spacers that go between the block and the intake. I didn't know what I didn't have so I had issues there. In order to get the whole thing to work I ended up buying headers anyway and that led to needing bigger pipes and all of that. It's a never ending story that a lot of us can tell on this board. One thing leads to another in the never ending quest for performance. That's the bad news I guess. The good news is that in spite of all the trials and tribulations, I'd buy the heads again. The car was dyno'd after the mods and I had 335hp at the rear wheels, more importantly was that the heads performed as promised. I don't have the dyno sheets in front of me but the torque curve was flat from 2,800 to 5,600 or something like that. It pulls all over the RPM range and that's what I was looking for. I've put over 10,000 miles on the car this summer, a lot of it on track and I haven't had any issues. If my wife didn't hate the car, she could probably drive it. There is another friend of mine locally who bought the 4V AFD's the same time as I got mine. He had a 408 or 393, I forget, and I think he had well over 500hp once again, proven on a dyno. I'll e mail him and tell him to write in his specifics. If you'd like to know more, give me a e mail and I'll go through my file at home and get out things like my cam card. One thing I do remember is that we kept adding advance and the engine loved it, I don't remember exactly where we ended up but the chamber shape was considered very efficient. It might have been as much as 40 total. As a side benefit, my mileage went up too. It's difficult to trust a Pantera gas gauge but I did the fill it up and then divide the mileage and how much it took to fill it back method. It might not be the most accurate. I took off a 650dp and went with a 770 Holley Street Avenger. I had major doubts but the engine guy said th trust him.
Where are you getting the heads from? I think there is a dealer in Illinois that is the official AFD dealer. While you're spending money, why don't you buy one of their Cleveland aluminum blocks and let us know how it works. I know they were supposed to be released soon. A few of us on this board would be candidates for that piece. Good luck and let me know if I can help. Vince
