Don just caught up with your thread,
Here in St.Louis we go to a repair shop for the safety inspection and then one of the State places for the sniff test on a dyno.(we usta do the sniff,but they decided we was cheating) 1971 and lower cars are exempt from the sniff test but everything has to have the safety, Now comes catch 22
Say if you install a 2004 engine into a 27 T , the law says ya gotta meet the 04 engine emmissions, Now it is the safety inspectors job to check for the proper emission devices ! We collect $12 for the safety test and the state gets $1.50 of that, I can tell ya that if a guy comes in with that 27T with a 04 engine I'm not about to fart around finding the engine numbers and then cross referencing for emission controls (not for $10.50) Now the ones I hate are the guy who shows up with a 88? camaro with a big block? all I can say is he's got problems cuzz I'm sure the powers to be would make an example out of the guy caught passing that one, (But it ain't gonna be me !!!! ) My little 5 window has the original 1931 title and thats what it's registered as, and I don't guess the Highway patrol is too concerened as I once got pulled over by em but the guy just thought it was cool and wanted to check it out.
