Tim Engler was very instrumental in supplying the stack injection for the P7. It was not just a matter of "adapting" the toyota or SB2 to the Dodge. The basic mold was used but a custom program was written for the cylinder heads. We supplied him with heads, valley cover and specific dimensions as well as air flow (cfm) to develop what is currently on the engine. He treated our project with as much attention as a team that would order multiple injection units (we only needed one). His help and advice after the fact has been second to none and always willing to listen and advise when asked. FWIW this engine is for sale (complete down to the custom converter) as we have moved to the 7.0 pro class with a 607 injected hemi. The 358" P7 achieved a best of 7.40 and more can be gotten but the hemi engine sort of just fell in our lap as a joint venture and we couldn't pass it up (besides it just looks plain sexy in a full bodied FED). If anyone has questions or wishes to inquire feel free to PM me.
