about valley crankshaft

Valley Crankshaft Inc. is a small, high performance machine shop, with 2 people on staff, and has been in business since 1984. We started as a crankshaft grinding and repair facility, and slowly evolved into a full service machine shop. Our capabilities include precision block, crank, rod, piston and cylinder head machining and assembly, using a full compliment of BHJ products.

MIG & TIG welding are also available in-house. Custom crankshaft work, including wet magnafluxing, offset grinding full radius at journal’s edge; indexing throws and nitrating are available. Custom cylinder head work, including valve guide repair, welding (aluminum only), radius/multi-angle valve seats, porting (using our Flow Data/Audie Tech acquisition flow bench), angle and flat milling, and chamber cc-ing are all available. We have a SF901 Super Flow engine dyno, so after the engine is built, we can break in, custom test & tune it for the application. This way we can ensure that you’ll get the maximum performance out of the engine. We have many dyno proven combinations.

Our customer base ranges from drag racing (NHRA Stock/Super Stock/Super classes/local brackets), some circle track racing applications, Sprint boats (from large cubic inch small block injected or alcohol to mid-size small blocks, carbureted on gas), marine performance inboard (mostly jet-drive white water river boats), and custom high performance street rods.

Eagle driver wins NHRA world championship

2011 has been a great year for Jackie & Mick Alley in NHRA drag racing. In April 2011, both Jackie & Mick won the first Division 6 race in Super Stock & Stock eliminator! (This was at the Ignitor race at Firebird Raceway in Eagle.) Pretty cool for a husband/wife team! Of course, they both received Wally trophies & money for the wins. In July, Jackie won her 1st National event in Denver.

Mick has also done well this year in Stock eliminator. He ended up #18 in the nation & #3 in Division 6. (which is not easy to do, either!) Jackie has been crowned the Super Stock World Champion (& of course the Champion in Super Stock Division 6!)


Idaho Statesman article

The NHRA awards ceremony was Monday night in Hollywood, CA. Jackie received a Wally (trophy), world championship coat & ring, & $15,000. Next year she will have #1 on her 69 Camaro S/S, showing her accomplishments. She is the first person from Idaho to win such a big title.

We also want to send a big Congratulations to Jackie & Mick Alley for all of their accomplishments in 2011! Great Job!
