With his dyno Quadrajet, John got 635 HP out of that engine. It made almost as much as his 041's. In his words, it was "nasty". At the time we did not realize that the little 48 mm throttle body was going to take 15-20 HP out of that number. But that's another story. Problem was, every 10 runs it was springing a water leak. They leaked everywhere, combustion chamber, runners, and bowls, they were just a junk scalloped head casting. Dave Layer and myself looked over available heads from Eldebrock, GM, and Dart. We came up with the 070 Dart as being our candidate. We hollered out to the ranks and several of us wrote letters to NHRA, along with Dave being on an every week chat line with Bruce. Eventually Bruce agreed to allow the head. Dave Layer made 4 sets, and three of those leaked almost immediately. So we reached back out to Bruce and ask if we could "Trade Up" to another casting. We choose the Dart 010 as it was thicker than the 070, and with SS being filled back up to the allowed spec's anyway, could he possibly allow it. He wanted to see it, and I drove a bare 010 Dart out to Indianapolis so Bruce could have a look at it. I awaited off to the side while he looked, measured, and thought. He agreed and we then built new Dart 010 heads. I don't think originally those 070's, or 010's made any faster ET's as the OEM 083 because of the 50 lbs. you had to put with them. But currently they are faster because of the relentless push from guys like Lincoln, among several others...

Bubski like "my god" You pick a combo with marginal cylinder heads !! Then lobby for replacement heads !! You shoulda picked a 2 barrel class and pissed and moaned you'd like a 4 barrel !! And all would be good in "class racing" What ever happened to choosing a combo ??
