She still don't run too bad for a 5 year old motor, first 3 passes 12.01-12.04, next 4 passes 11.91-11.98 with 60ft times ranging from 1.67-1.70 on drag radials,mph was 110-111. Its hard to tell how much the th400 swap back to a th350 helped since it is compared on two different tracks and last time at this track it was an 1/8th mile race, but it seems to have picked up a tenth at least. Best e.t. all year at the 1000ft track was 9.99 and best 1000ft time today was 9.89 and all passes today were 1/4 mile passes. I think I'll stick with the th350 for a while graemlins/thumbsup.gif
I'm only picking up 21-22 mph from the 1/8th mile on so I'm guessing the valve springs are gettin weak,no cutting out or missing noticed, just kinda lazy on the big end. I told the guy that has my block,heads,and cam that I want a 10 second time slip from the new motor,so we'll see next spring. Until then, wheels up :D
