Don, how did it feel onthe gear changes? When I killed one of my converters it felt like it slid into gear. I could hear and feel it shift but my friends watching said they couldn't hear it shift. There was very little fall back.
When I ran the 340 with a 9 1/2" converter that flashed 5000, 727, 4.30 gears with a 275 radial, at 3260# it ran 7.24-28 at 94 mph with 1.54-58 60' and 11.60 at 116 on cal tracs.
Second to third shift felt like a new car, not sure how else to describe it. Car is remarkably consistent to the 1/8 mile, as i said all the mph and ET’s were the same on every pass.
It was only in high gear where the mph was off.
Not sure exactly what your combo was, they are all different.... lol.
This 360 is literally bone stock. Stock crank, rods, and stock 30 over factory replacement cast slugs, factory 28 thou in the hole. I milled the heads to up the compression a bit
Big cam, dinky 1 5/8 tube headers and factory flat steel hood with no scoop.
It actually made very good mph with the 727 ( 118+) last year, for what it is, was extremely happy. I figured it would go 120 ish with the new convertor and this tranny. I think like 340Rick does( my buddy who called) the tranny is slipping.... hurting trap mph and slowing the back half of the track results down. I figured the car would run 11.20’s last night, and in great air threaten the 10’s
I mean, running 11.39 at 113 mph, something aint right.... lol.......
Here are the incrementals on that pass:
60 foot.... 1.553
330.........4.60
1/8..........7.201
1/8 mph....94.12
1000 et......9.459
1000 mph....107.71
1/4...........11.395
1/4 mph......113.35
Something aint right there........
Edit..... and here are the incrimentals a short while later( same air)
60 foot...... 1.554
330............4.614
1/8 mile......7.206
1/8... mph...94.56
1000......... 9.456
1000 mph.....108.15
1/4...............11.374
1/4 mph.........116.94
Still “off” but better...... this pass and the one above are the quickest the car has ever been other than on that last mineshaft air outing last year..... and even that night, only that one pass was in the 20’s......... its just not picking up from the 1/8 to the finish line..... its worse.
