I like the hood, who makes it? Looks like it fits perfect.

It's just a regular 2" cowl Goodmark hood and I added a pair of Race Louvers.

Thanks.

More progress on my attempt at adding downforce to a brick!

For the most part, this car has always had a front spoiler with a very small splitter. Was it effective? I have no idea. However, after doing some reading and seeing what successful racers have done, I decided to improve (I hope) my aero situation.

The first step was choosing material - in this case Sande plywood from HD. It was the least expensive of the nice plywood. Then I drew a pattern and transferred it to the plywood, cut it out, etc. In an effort to reduce weight, I used a router to cut some pockets in it.

Then I fabbed a pair of splitter ramps because they add downforce without adding drag.

And because all the cool kids are doing it, I made some end plates.

Because this slab of wood will be on a car in various environments, I coated it in DIY bedliner that was left over from my C10.

After a quick drive I measured my ground clearance at 4". The lowest part of the car is the passenger side link for the Watts. If you look close you can see it back there by the tire.

This last one is just because it's a good pic. :)

Looks great, perfect size that doesn't look out of place.
Nice fabrication skills there.
Let us know if you notice a difference.

Much agreed x2. Update when you have some seat time data.

Last weekend I brought the Chevelle to the Northeast Musclecar Challenge. This was the first road course I've had it on and it impressed me. It went where I pointed it, the power was awesome, it felt planted, and considering the brakes are standard Baer 6P with Bluestuff pads, it stopped on a dime! So overall the car did well, placed about mid pack on the road course and autox. With more seat time, it can only get better!

Last weekend I entered the Chevelle in the Optima USCA event at NCM. Overall it was a good time but there are still some teething pains that I need to work out, but mainly I need to learn how to drive this thing!

On Saturday morning I was having a hard time getting around the autox. The course was a bit long in areas to stay in first, so I had to shift into second. I'm trying to learn left foot braking but when I throw in a shift here and there, things didn't work out the best! In the afternoon I went back to right foot braking and added some compression to the rear shocks and things started to improve to the tune of dropping about 7 seconds off my morning runs.

On Sunday was the road course, which was fun but I noticed a vibration in the car after going into a turn a little too hot and driving over the rumble strips (more like huge speed bumps). By the third session I decided to come in and not chance it with the vibes getting worse.

One of the coolest things of this event - and a huge surprise to me - I won the Driver's Choice award! That was nice knowing my fellow drivers liked my car enough to select it. :thumbsup:

After I unpacked the trailer, I put the car on the lift to inspect it and everything structural is still in tact! All my welds look good, nothing is bent, and the wheels are still round! I think the vibrations are coming from the clutch, but I won't know for sure until I have a chance to pull the trans.
