Not black or aluminum on the valve covers (yellow Chromabase/clear), but the whistler is black p/c.

Here is what Rustoleum Hi Temp silver paint will do to a stock L98 engine. In order for the paint to adhere to the cast metal, you should use a good zinc chromate primer. Here is a photo taken last spring of my 89 engine:

Can't run long tubes in California. I changed the intake because I read that the stock plenum is too restictive. I have 1.6 RRs, a 2400 Vigilante and downsized pullys. The vert is my dd. So far my best et is 13.7. I'm not really concerned with 1/4 mile times. It's quiet, looks good and very reliable. I've been driving it for 6 years.

That's gorgeous! Did you have to clearance the sides of the runners in order for those valve covers to work or did they bolt right on?

Really bad picture with my camera phone after the catch can install. I'll have to take some new ones. You can't see it well fom this angle but they are Edelbrock valve covers,

I averaged 25 MPG on a long trip that was mostly highway when I had the 2.73 gears. I haven't checked the mileage on the 3.07s but I'm sure it's a little lower.

I had a mail order tune from Fastchip. http://www.fastchip.com/ I wanted a Vette that was reliable, nice looking and had good streetabilty. I didn't want to spend a fortune trying to add HP. I also had to keep the Vette California smog legal.

When I bought my 88 it was bone stock. The best ET I could manage was 14.6. GM advertising claimed the 88 ran a 14.4 with a top speed of 155 MPH. So I think that running a 13.7 with a basically stock, California smog legal 88 is pretty good. I got the 13.7 with a 2.0 60. The tranny was shifting automatically at 4800 RPMs. I think with a new governor and a better 60, I can get a better ET.

It's black wrinkle powdercoating, actually.

Thanks! I plan on doing the fuel rails to match at some point, too. Never got around to that.
