I was heading back to work this afternoon after getting a haircut. And a jetta came up beside me and the driver gave my the classic two finger "Wanna race" signal. Im in my 81 Cutlass Diesel 350. I just look over and shake my head No. I know why he did it. I just install my 5in Autogage Tach w/shiftlight (That was in my CamarOlds. Its not hooked up, but nor is it getting banged around in the back seat no more). And I have 15x8.5 with 275/60/15 rear tires so I guess it could looked tempting. And I did past him first then he pulled back up next to me. LOL, I have a Th200 tranny (I think, it the one that looks like a th-350 but has metric on the pan.) and 2.18 rear end gear with a Olds 350 diesel in front. Im lucky to beat traffic, much less a jetta. So now Im worked up about installing the 455 as-is again. BUT even if I had the 455 installed. I really dont care to street race. And especially not the highway I was on. What not happening my decision is I thought I was getting in the mid 20's mpg. But it seems Im avg arouind 18-20 mpg. So not bad. But not as good as thought.
