From what is being posted in this entire thread it is very apparent that my write-up does contain numerous errors. I knew very little about the motor before the DePue Reunion and talked to a lot of people about it at that event. A lot was said and it was difficult to separate fact from fiction (as Wayne suggested, I obviously captured some of both). From your great input, I can now go back and revise my write-up to set the facts straight. I do sincerely appreciate all of your comments... they have all been very helpful.
I thought the water injection system was something that Joe Michelini had added. I was told at DePue that the 1/8" tubes entering the exhaust header pipes were there when the powerhead was received by Marshall. Since they were never used when the motor was raced, the injection system should be removed to be more historically correct and each of the four entry tubes should be capped. I will take off the incorrect graphics (they were on the motor when I got it) and try to match the paint with colors that can be seen in the early pictures of this motor that were posted on BRF in the past. Thanks again for the help.
