However, when i shortened the tips up a little, I did notice some discoloration on the paint. Nothing permanent, just obviously dirtier when you wash it.
However, if your running real rich or cold starting, AND have short exhaust tips, AND didn't wash it often, I'm sure you could stain the paint in some way...kinda like cigarettes on teeth.

The other things to keep in mind are; that style exhaust runs OUTSIDE the fender, has NO crossover, and is limited to bullet mufflers. You can use a similar exit without using the entire style of exhaust, but the "J-Turn" to get the exhaust through the side is tricky.....the actual layout of things results in some tighter bends than are ideal. When I re-do it in mandrel, we are trying to take some of the sharp turns out of the path. Also, it drones a LOT on the hwy.

Do you think it drones a lot because is bouncing off the rear fender. I'm going fleet side. Wondering if it will cause a problem. The heat has no effect to the paint so far?

Well it doesn't bounce off the rear fender...it passes through the step, but doesn't really touch the step or the fender.

The droning is the result of running an LS motor with no crossover, small bullet resonator/mufflers, and a sharp-turning exit that lands directly behind the cab.

To eliminate the drone, I need to go mandrel bent, add a crossover, and possibly change the muffler style.

[texasld]

I meant the sound waves bouncing off the fender. But that is some great info for when I get my LS fitted and the exhaust run.

[BR3W CITY]

Well if you could dye the exhaust, the actual angle of the exhaust points past the fender. I'm sure it can echo a bit, but you don't really hear "body" drone, its purely the sorta-unusual sound of the shape and type of exhaust.

[texasld]

Got ya! Thank you for the answers. I really want to do side exit exhaust, but I'm hesitant.

On a fleet body, you'll want to consider something like they use in boating. Its basically a "Bulkhead" exhaust tip. It bolts to the body with a stainless or aluminum shroud around the edge, giving you a clean exit instead of exposed-cut-sheetmetal.

[texasld]

That's exactly what I'm looking at. They look really awesome!

[pdxhall]

those bulkhead exhaust ends are just what I've been looking for. Do you have more info on them?

They are dumb-expensive, and the easiest place to find them is boat-supply places. There are a few different kinds, and you gotta be a little bit careful.

Some of them have an internal "flapper" that swings closed when there isn't exhaust pressure coming out. Its a boat thing, but on a car it rattles and pings. Also, some hard-mount to the body, which means that you need a good mount/flex point in your exhaust or it will transfer a ton of vibration back into the body.

[texasld]

Here are some that I found. Reasonable price, I wonder about heat shield though.

A WILD project we did. This is another Plasti-Dip special, but we use a VERY special thermochromatic pigment....BCUZ HOTWHEELSCAR!

A very cool truck I saw at a local cruise-in











And of course me taking pics of my own truck

[BR3W CITY]

Finally snagged my new-to-me heads from a friend. They are good ole 317's, but they've been milled a tad dropping the chamber by about 2cc's. They have also been fully worked...and I mean freakin worked...by a 40+ year veteran and instructor at S.A.M.

They have new gm valves with a full valve job, topped with Brian Tooley Racing platinum dual springs and Titanium retainers and all the other locks/seals/etc. I'm tempted to add new rockers as well when we open it up to eliminate the needle bearing concern. We ran and proved these heads on our fbody for a while and made excellent power.

What paint is on the truck now? I'm really digging the satin theme

Thanks Chris. The truck is the same Satin Blue that its been for a couple years...

Are you asking what type of paint it is or am I reading something wrong???

[Chris Coufal]

Yes sir....what type of paint.

[BR3W CITY]

Its good ole' 3 stage paint, prime-base-clear. You'd paint it the same as any other car, but we used a satin clear (regular clearcoat with flattening agent).

[Chris Coufal]

got it! Thanks!

[ChrisDollins]

Digging the truck and the vids. The heads look really good! Cool to see someone else from the fbody crowd.

Hey Chris, if your an Fbody fan keep an eye on the youtube channel and here on my build. I'll be putting up some pics and video of that 'bird soon. We ran it at Gingerman Raceway this weekend, and the combo of big power and big brakes on stock suspension resulted in shearing the torque arm, and left peices of the 10bolt in the drain pan.

I'm fabbing a 9inch rear for it, and we are doing a full pro touring suspension in prep for next year.

[ChrisDollins]

Awesome! (The car not the damage lol) Was it the stock torque arm? 9" will be nice. I've only ran the Moser 12 bolts, but the easy gearing changes with the 9" would be nice. It's been a while since I've done anything over on tech, but my user name is CHRIZ28 over there. Never did anything pro-touring, would be a blast though! Wanted to go more pt with the Firehawk, just ended up selling it. Would love to go pt with the 66. Just way more places to play on a drag strip around than autocross or road course around here.

Chris

Very cool man. Here are some pics from the fiasco at Gingerman. I'll have to get my buddies cell phone pics that showed the sheared arm. You can barely see it in the side up picture. You can see where the wheel collided into the wheel well and ripped the undercoating off, and the rim scored it slightly above the shock. We were surprised this didnt' shred a tire or rip it off the rim...it was fine?

[ChrisDollins]

Good looking car! I'll always have a soft spot for 4th gens. Time to get some suspension under that car for sure! I had really good luck with a spohn subframe mounted torque arm with two loops. Can't wait to see what you do with it. Oh, and the truck too lol. Do you post over on tech?

I lurk there for some info, but don't post there much anymore due to a number of individuals on that forum being so ignorant that they actively hurt the community with bad information.

Despite my mag credentials, and his (the t/a title'd owner) being a tuner and mech engineer for an OEM of GM...folks don't like to listen to advice or opinions that didn't fit the crowd.

We took engine dyno sheets from a cam we spec'd over their to share with some folks looking for advice. Despite hard #'s, we got **** on by posters because we second-guessed Pat G (and you know exactly how thats recieved over there). He re-spec'd a cam that matched ours in all but 1 dimension, and they fanboyed hard. I just can't do it over there.

Other than here, I like YellowBullet, since at least the poo-slinging is omni directional, and anyone with #'s or slips can make their own respect.
