And even more:
These pics were TOP SECRET many years ago!! (Not kidding)
These are the "pinned deck" development on 8445 castings, to beef up the intake side of the combustion chamber/deck. This was developed by Dale Robertson. (genious) We did this about 16+ years ago when there weren't injectors that would fuel the engines. (I replaced head gaskets like most people change oil.) We thought it was caused by the VERY thin deck in that area. Now, we just dump fuel to them and the gaskets hold fine. It was alot of work to do right. But it DID help the gasket problems significantly. I would pre-load the deck .002" in that area (which is RIGHT were the fire ring on a stock gasket falls) I did this when I was running stock injectors, stock turbo, stock intercooler and went 11.77@112mph back in 1991. Man, those were the days!!:biggrin: Martyrs we were!!!
I can recall long conversations with Conley (he said that 112mph on a stock turbo was IMPOSSIBLE. I DID have a GREAT set of heads on the car, though!
) Jay Carter (about 7th injector and alcohol systems....as a matter of fact one of his alcohol systems was JUST removed last month-It was highly modified, but it ran 10.70's on pump gas.) and a host of other Martyrs (Don Kieger, Phil from ATR, Terry Ryan.....and the list goes on and on.......Wouldn't it be fun to take the technology of today, and run a pump gas car into the low tens with a stock block, back 15 years ago?
