Looks great, Cris. What's the purpose of the vapor dome?

Is there any updates?

very cool build!

I'm also curious of the vapor domes purpose?

The purpose is so that once the tank is full of liquid (no higher than the filler neck) there is a space above the liquid line for venting. Having this.space helps prevent the liquid from being sucked, or pushed, into the vent line.

Does there need to be a vent in the dome?

How is the rear spoiler mounted, thanks

Looks good! How's the clearance of your oil pan to your steering centerlink? My LS3 mock up in my 72 LT-1 dosent have much room unless I leave the motor sitting 1.5" higher than I would like to.......

Chris......one thing about your Vette......there should be some plastic Rock guards mounted to tabs on the front horseshoe bracket to prevent head light breakage.....these are commonly missing on C3 Vettes but, you might want to install some. Try Wilcox Corvette for these parts if you don't have them.

Do yourself another favor.......since your not going 5 link.....you can notch and relocate the differential about 3/4" upwards to improve your half shaft angles.....once they go over center you get rear wheel toe-out which is a pretty deadly condition on handling. Take out the front differential bushing and machine a thin solid spacer. You might also want to look at Toms Differentials for the rear Xmember bracing kit they sold for drag racing...I would add some help to that part for a high HP application. Look at an old Chevy Power manual in the Corvette frame modification section and see where there might be possible shock body interference in the front frame pockets and see if you need to make that modification. It looks like you have the Borgeson steering box.....look at the Ridetech steering box brace.....it's a pretty nice part. There is lots of high polar weight loss if you redo some of the front radiator lower support "V" brace and bumper bracing along with going to the FIA style headlamp set up. Ridetech also went to a glass front bumper grille set up.....again a few pounds of high polar weight.....I'm thinking about doing a glass bumper and making it look chrome again for my Vette. If that Vette still has its tilt/tele steering column in it.....I'd get rid of it for autocross thrashing......at least go through it and tighten everything up or one day you will be met with a loud CRACK! And loose column.

I'm sure you probably have gotten past it but, I went to an Edelbrock water pump and welded in bungs on the top for my heater hoses to get upper control arm shaft clearance for heater hoses.....the Edelbrock pump has a cartridge impeller that can be taken out for housing welding. My drive set up is a modified Ventura Speed Shop LS drive.

Thank you sir for all the advise! I have been finding all the strenghts & weakness of my C3. I finally have it up & running & have been driving the crap outta my car.. Last week I had Danny Popp in town with JJ Furillo from Ultimate Performance getting my car dialed in.. Car is working great but woking making more changes..

Here are the shots of me driving my car @ USCA in Fontana last weekend.. with Streests of Willow & Camarillo Airport..
