[FireSale]

When I broke into racing I built a 68 302 for SS/GT using the AFR 1399 aluminum heads that are listed as legal in the book. It would cost a lot of cash to get the right size valves in those heads and there are only a few machine shops that will take the job on. I sold mine to Brian Thompson and run iron heads in bracket. Don't make that mistake.
On the subject of your combo being competitive heads up, take that with a grain of salt. Class racing is rather thin these days with the exception of a few big National events. Running under the index will move you up the ladder, but for the most part it's a bracket race of very nice cars. Just be reminded that you can't dial over your class index. A 12.99 index car can't dial 13.00.
Find Thompson, Seaburg and Biscay at Bremerton or Pacific. The best Ford builders and tuners around. Biscay is a Chevy/Bike guy, but he's fun.
Pacific Raceway: Bracket Kings This Friday-Saturday (money race)
Woodburn Raceway: D6 Bracket Finals first weekend in September.
I'll be around but my car is out for the season. Red 68 with white Shelby stripes and a real pissy oil leak.
