Do I need a new converter?
Hey Mopar gurus,
I'm just getting around to running my 67 Dart on the track. So far just 1/8th mile, as that's my local track. It's best ET is 7.68 @ 90.18mph with a 1.70 60' on the following setup:
410 small block with ported Eddy's
TTI step headers
1.5 Crane gold rockers
Hughes hydraulic 246/250 4650ALN-10 cam
Scat 4" crank, Diamond -20cc pistons 0 deck, stud girdle, 10.3:1 compression
port-matched AirGap intake
Fitech EFI 600 unit
727 with manual valve body TF3 kit, bolt in sprag, 4.0lever, deep pan
10" converter that I can hold on the footbrake to about 2500 or so.... I pulled this out of another car and have no idea of its specs or origin.
8 3/4 with 4.30 spool, Dutchman axles, narrowed, mini-tub, inboard springs
295/55/15 MT ET drag radials (27.7" tall, about 10" of tread contacting the ground)
New mono-leaf and Caltrack setup from Calvert
So.... It has hooked well, haven't noticed any spinning, but there's a bit of a lag right off the line, not like it's bogging down, just taking it's time to hit the power band it seems like, before the torque really sets you back. I feel like if I could footbrake to a higher RPM it would rocket out of there. I just think I'm leaving a lot on the table, and this setup should have a much better 60'.
Am I right in thinking this unknown 10" converter is my weak link???
