67 Cyclone
« on: May 23, 2015, 05:35:44 AM »
In the spirit of shady's 62 Galaxie post, here's another report from the 'looks good but none too fast' club.

Performance Summary:
      1/4 mile ET: 15.741   1/4 mile MPH: 88.69
      1/8 mile ET: 10.229   1/8 mile MPH: 73.46
      60 foot time: 2.58
      Track: Virginia Motorsports Park Test & Tune, Dinwiddie VA (well prepped and sticky)
      Weather Conditions: excellent, sunny, 78F, low humidity (6.29 PM)

Vehicle Use: Street
Model Year: 1967
Model: Cyclone
Style: 2-door hardtop
Engine Details: +.030 390 (396 cid?); stock C7 heads, FPA headers, PI intake, Comp XE 256 cam, Holley 650 vacuum sec
Transmission: C6 (with a massive half-track 2-3 shift flare, as I discovered to my great surprise on track at WOT)
Torque converter details (if automatic): stock 1967 Ford
Driveshaft: stock
U-joints: stock
Rear end type: 9-in
Differential type: Track Lok
Gear Ratio: 3.00: 1
Axles: stock
Front tires: 225/70-15 BFG TAs
Front wheels: 15x7 Rocket Fuel Greys
Rear tires: 235/70-15 BFG TAs
Rear wheels: 15x7 Rocket Fuel Greys
Front suspension information: stock
Rear suspension information: stock
Ready-to-race vehicle weight, including driver: 3640 lbs

I was initially quite disappointed; had deluded myself into thinking a low-15ish ET was possible with trap speed in the mid-90s. But with the 2-3 shift issue (which I think prob cost at least .5 sec) and non-optimal (for the drag strip) 3:1 rear gearing I've since got over my hurt feelings. And I'm quite certain there were spectators who were able to get a hamburger and soft drink from the snack bar in the same time it took me to get to 60 feet. On the plus side, on the 190 mile round trip to-from Dinwiddie, the old girl returned a new best of 15 mpg!

Sounds Great!
With the 3.00 and the 235/70-15's your actually giving up gear compared to the
bias ply 14's of the day, and those BFG's are extremely traction limited.
Bet you had to beat the grin off your mug. ;D

I'm smiling even more now, Howie.  Just got back a few mins ago from the local Sunoco station after having tanked up on 93 octane @ $2.93/gal.  Re-did my earlier calculations and yesterday's trip, incl 2 passes down the track, averaged 18.5 mpg  ;D

If it were any better the darn thing would be making gas!

Yeah, well...a little too awesome as it turns out.  14.5, not 18.5.  Good thing I'm not in finance.
