Experience & Diversity:

A Winning Combination

for Thunder Works' Customers 

Marv Grogan's experience covers the spectrum of gasoline (and alcohol) powered performance: domestic big blocks and small blocks; foreign/imports; and all racing applications whether drag, round, or dirt track. Not to forget the off-road enthusiasts - desert racing, rock crawling, etc.; Oh, and all the inboard marine engines. And then there's the antiques and vintage restorations. Along with... (you get the idea).

Why so many different aspects for one little shop and one master machinist? Because quality machining applies to all things high performance. Doesn't matter if it's a blown big block Chevy or a 2JZ Toyota 6-cylinder; a Ford V8 Flathead or Model A (or B or C!) to a 520i BMW.

The common denominators here are simple: Knowledge, machining experience, and attention to detail.

In other words, Thunder Works. 

Where Did the Year Go?!

Cold weather is here and the holidays are coming up fast. Sadly, the warm-weather engine sports (asphalt racing, cruise nights, and speed-boats) have pretty much come to an end until next year.

But the cooler temps bring out the desert sand-car nuts--er, enthusiasts, and the off-road racers, ready for their run for glory. The holidays also mean a breather for us when we can catch up on our backlog.

Our customers who are "planners" (you know who you are), know that NOW is the time to get your engine pulled and brought in to be (at least) freshened up or (best case) rebuilt into the monster you've always wanted. With winter, you've got the time to do your project right rather than waiting, and having to thrash out an all-nighter right before your vacation, just to get your toy done so you can have fun, too.

And lest ye forget: engine-work is a great gift-giving idea, for the family who doesn't know what to get the motorhead who probably already has every tool. Thunder Works' gift certificates are available in any amount, as are escrow accounts for when you and your engine are ready to go to the next level.

So bring in your project engine and get it estimated, so you can start dropping hints about what your loving spouse and/or kids can get you for Christmas. It won't fit under the tree, but when you fire up your engine after it's been rebuilt, we guarantee your grin will fill that empty stocking.
