The cars that run the F.A.S.T. series are no where near factory stock. The Vette has a 511 ci L-88 aluminum headed engine that was dynoed @ 650 fwhp. Another of the fastest cars, a Hemi Road Runner clone, has a 498 ci Hemi with @ 615 at the wheels and 14.0:1. To quote the owner, "It's basically a Super Stock motor". I was reading articles in Hot Rod (Dec. 06 and Jan 07 issues) about them today. The rules allow unlimited displacement increases and other internal modifications within the limits of a stock-appearing block. Largest tire allowed is a G-60 if the car came with them, otherwise it is a G-70 on 6 inch wide rims. They allow basic suspension mods, shocks, springs, bushings, snubbers, and clamped springs but no bolt on traction devices. It also has a catagory that allows parts as long as they appear correct for that year, make, and model.
The Jan issue had the Vette, the RR, and a Stage 1 GS facing off on slicks. The GS was not a normal F.A.S.T. racer. Infact the article said that it was the first time that car had been on the track. They were bashing the Buick about having T/A aluminum heads which would not be allowed in the series. The Buick was the slowest of the three but IIRC it still pulled some high 10's and as far as I know it did it with the stock displacement, un-stroked 455. It did dyno highest out of the three but out wieghed the Vette by around 800 lbs.
There is a factory stock class as well with a lot stricter rules but the fastest cars in that class are 11.70's-11.90's.
I think a stroked 4.1 with a carefully sorted combo and GNX suspension could be very competative. The series requires bias ply tires but I've always heard they could hook better than stock radials. The only real problem I see is the same as at many car shows we go to. It is only open to '55 to '74 muscle cars. We are black sheeps again. baa.....baa
:biggrin:
I have been 1.64 60 foot on a real radial but only on 22# of boost. More boost and it would spin when it reached about 24# of boost. My best time was 7.36 in FAST trim. I never tried to run the class but was curious what my car would do in that style of a class. That's enough for mid 11's. I know I could go low 11's but it would take some type of boost controller or some way of controlling the timing to make it easier on the tires. Or you just have to be really consistent at manually controlling the throttle. It's hard to peddle a turbo car and still be consistent.
