Stan here is the real deal.... The "E" motor is much faster than the "C" motor,,,, I never ran the "E" hard....(it is kinda special lil motor and we took it out to save for Bonneville in the 53 Stude we are building... ) The E however needed to rev high and with the rear gear I had and the auto she dropped to many RPM's on the shift from 2nd to 3rd.. and was just recovering at the finish line,,, The Vicky is street legal and licensed and insured, I decided that the Stude would be purpose built for racing only,, so took the E out for the Stude,,,, The C motor is just a street motor (well a hot street motor) only 11 to 1 compression .... The C motor however has never made a full pass on power either,,, This April we did 143.xx and 146.xxx when she nosed over and quit pulling and was stuttering like a lean out condition and I rolled out of it and coasted across the line,,, (found water in the tank ) In May we made one pass and she stuttered the whole way down (in car camera video sound is not good but if you play it on good speakers you can hear the stumbles and hear that I never hit the the secondaries till 1/2 track and then pedaled and held flat.. to finish..)
I had no idea what was going on,, but we think we found most of the problem,,, the Ground wire to the MSD box was loose and the ring terminal was about broke in half... kinda like the plugs where being blown out...we have since ran new wires and man the motor revs much faster,,, now we have to re jet and should be ok,,,, I WILL DO 154.xxx in 2 weeks,,, record is 152.xxx
(FYI,,, the car is only tech'd to 150mph,,, so I am only allowed to go 155 max... the class record is well within my reach with this car.... now I know the Stude "should" handle better and is for sure going to be more areo than my Vicky (brick)
Does that help,,,,,
I know you still wanna know why a 370 only beats a 255 by less than 10mph,,,, the reason is beat around the bush in the above text,,,, LOL,,, I think you know
Talk soon,, why don't you join us some time on Tuesday night chat ?
