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.
