Thanks for the responses.
So John, 1/4 only , l use the rear gear to regulate rpm at the stripe. 4.10:1 105 inch tire , 138-140 mph. 6900 rpm 4.5 stroke. Stock poured block billet splayed caps.
Race only and car shows. I built the car as a retirement dream.
Please give me a specific hydro fluid to try.
As far as flashing the converter the shift light doesn’t go out between first and second and barely goes of for one second in high gear.
This isn’t a serious race effort, just a second childhood thing. I don’t have data acquisition hell I still struggle with my cell phone!!!
John we are practically neighbors, I’m in Phoenixville.
