There is an interesting TV show I get on early Saturday mornings on a Fox affiliated station. It is called POWERBLOCK.TV.
These guys are always modifying stuff & are interesting to watch. I am pretty sure they have a website. I would give them a try.
As for all the kudos you are getting over keeping a 1998 car running——I still drive a 1976 1 ton Dually 454 Chevy truck—hauling my horses. It has 347,000 ++ miles on it. I have had it for almost 31 years. My ‘daily driver’ is a 1979 Buick Station wagon with a 403 Olds engine. I have had it for over 35 years & it has over 211,000 miles on it.
Let me know if you get info from the POWERBLOCK TV guys.
I’ll have to look for that show myself.
