yup just stick to side work out of your home garage. Keep it low key so no one bitches to zoning about you running a repair shop out of your residential home. Easy to make 4-500 a week doing bs or do a few cam swaps and performance upgrades and make a bunch more. For what alot of shops are quoting to do cam swaps in SBF/LSX/SBC stuff and people are paying it, you could really come in under these numbers to provide the exact same service.
