With those rules and trying to win, I don't see how you could look past an early 70's Torino or Mustang with a 620" 385 series. But if loyal to the FE like most of us on here, I would build a MR 66-67 Fairlane.

Like the idea of a big CID engine but.....

I wonder, if like in the old days, one took a small CID engine and wound it up to killer rpms, if it would be competitive. I only bring this up if big engines would blow of the tires and kill the 0-60 ft. times. Thinking of MP classes where (sadly) small CID SBC's killed a lot of classes (C/MP, D/MP, etc.).

If one can't well hook up the mandated small tires....the one that does wins.

14.00 TIRES AND WHEELS AND BRAKES

14.01 Wheels must be correct*, including correct* diameter, width and material.

Note: Width may be upgraded to a maximum of 6”, if the correct* wheel is narrower than that. Reproduction wheels OK.

14.02 All 4 wheels and tires must be same size.

Exception: Mopar TA Challenger came from factory with G-60’s on rear and F-60’s on front.

14.03 Original equipment reproduction bias-ply tires only. No soft compound tires of any kind are allowed.

Retread tires are not allowed. Any car is allowed to upgrade to a maximum size tire of G-70 of the correct* wheel diameter.

All cars that were originally available with a 60 series tire can upgrade to a maximum size of G-60 tire of the correct* wheel diameter.

Exception: First time F.A.S.T. participants are allowed to run normal ’non-sticky’ street radials for their first F.A.S.T. race.

So....... Where do you get these tires?

How about these G60's

In 2009 Lane Carey took a 71 MACh1 429 SCJ to a F.A.S.T. record of 9.84 making 800+ HP. 

It was featured in Hemmings: Ford 385-series "big-block" V-8, cast-iron block and cylinder heads Block -- Ford casting number D0VE (1970), service-replacement 460; two-bolt main converted to four-bolt splayed caps, cooling jackets filled with "hard block" and fitted with screw-in core plugs Cylinder heads -- Ford casting number D0OE-R (1970-'71 429 CJ/SCJ) Camshaft -- Custom, gun-drilled solid-roller of undisclosed specifications, by Bullet Racing Cams, mounted in roller bearings Valvetrain -- Shaft-mount aluminum roller-rocker arms by W.W. Engineering, Jesel mechanical roller lifters Pistons -- Ross custom-forged with titanium wrist pins Connecting rods -- GRP Pro-Stock aluminum Crankshaft -- Crower custom billet Ultralight knife-edged, pendulum-cut, gun-drilled, with 351C main-journal diameter Displacement -- 588 cubic inches Bore x stroke -- 4.450 x 4.750 inches Compression ratio -- 14.7:1 Horsepower @ RPM -- 825 @ 6,200 Torque @ RPM -- Approximately 800 @ 4,500 Fuel system -

Awesome car!

I assume any safety features like a cage are allowed, even though it is certainly not factory appearing?

Again, where do you get bias, non soft, G60 or 70 tires that will get you into the 9's?

Jack Chrisman, in his Comet, with soft, wide slicks didn't go much faster than that. Slower in his first year, I think.

They use the available reproduction tires, with some prep work. I think our resident FAST racer Hemi Joel is busy working on his Drag Week Coupe at the moment, maybe he will come back on at some point with more details. Starting line launch technique is the key, you can’t launch it like something with slicks obviously.

Obviously the car would be MUCH quicker with slicks, based on 1.52 60 foot times, I would guess at least 1/2 second quicker with slicks. With over 800 HP, I imagine that they are leaving with these cars with timing pulled back, and leaving at part throttle. Sounds like a pretty radical engine combination, and I imagine despite plenty of work on the iron heads, intake and exhaust manifolds, there is a fair bit more power to be had with better aftermarket components, but it was built to meet the pretty liberal rules of the  FAST rulebook. Much like NHRA Stock and Super Stock, racers find ways to optimize their combinations in spite of what appear to be restrictive rules.

[Hemi Joel]

Frank, the tires are right out of the Coker catalog.  It is so fun to go to a test and tune, or bracket race with a FAST car, that looks 100% stock including exhaust to the rear bumper and G70-14's, then at the 1000' drive on past a race car on slicks with open headers, that has the whole Summit catalog thrown at it. Then leave the hood open in the pits and watch from afar as racers look it over, look under it, and get a puzzled look.

That is the magic of FAST!

[mbrunson427]

OK how about this one....... '65 Galaxie 427. This is virtually the same engine combo as the 66-67 Fairlane, but gets long tube headers. Has a coil spring rear end with ladder bars. I'd think you could get it to hook?! Of course there's a weight penalty here, but it seems to me that making the power isn't the problem, it's applying the power that gets you.

[frnkeore]

Joel, thank you for explaining that for me.

[babybolt]

The 66 67 Fairlane 427 right side exhaust manifold might be a bottleneck.

Heard that for another Ford engine, someone had aluminum exhaust manifolds cast for the FAST series.  Easier to port.

[4twennyAint]

65 Galaxy exhaust is definitely the one for sleeper power.  What's the biggest tire option that year...police pkg?
