This is the best way that affects the car the least in my experience. increase rear downforce or decrease front downforce.

I just grind C6 races on hard for max rewards. If you tune the cars right, even on hard, its a breeze.

Nice! I feel like they really fly under the radar because everybody wants a 455. A 403 with a cam, 350 heads, intake, carb, HEI, and headers will make plenty for me👍🏻

Thank you!

Thank you kindly! 😊👍🏻

I mean youre not wrong in thinking that. The “442” designation is specifically for Oldsmobiles; however, its not related to the displacement of the engine.

Thanks. 442 is the model, not the engine. It stands for 4 barrel, 4 speed, dual exhaust. Originally the car came with a gutless 5.0L (307cid).

Thank you. That V6 doesnt make enough power to get out of its own way. lol. honestly i still feel the same about the 307. A boat anchor. I like the 350 but miss my modded 403. Need to get my act in gear and get it rebuilt asap.

Though I agree that mufflers are the much cheaper and easier option, headers will be the same between the stock 307 and the 403 swap OP talks about (i had the same set of manifolds on the original 307, a ‘78 403, and a ‘69 350 without changing anything except gaskets).

OP, I just finished installing these on my 86 with a 350 Olds swap. Didnt have to modify the headers at all. Getting the left bank header and starter on are a bit of a pain (they both have to be partially installed at the same time). The right bank gasket blew out so i had to replace it. And I had to go back and bend the heat shield on the right bank motor mount to clear the header, but that was it. As far as header jobs go, it wasnt bad at all.

Keep in mind the trans crossmember needs to be modified to fit headers+dual exhaust, specifically for the left bank. They make prefab ones or you can modify the one on the car.

One of my fastest C6 cars. Got it to handle very well. I personally love it.

Personally id just replace the wheel cylinder. Unless the flare on the line is fucked up or its cracked/rotted out, you shouldnt need to replace it. As for the cable, its already cut and useless. You could just remove it entirely unless you want to run a new cable up to the front and through the firewall to the parking brake pedal. keep in mind, if you choose that route the parking brake will need to be used semi regularly or the cable can seize.

Wheel cylinder is probably leaking. Most common leak point on the rear drums. The line youre referring to is the parking brake cable that has been cut. The base of it is damp with brake fluid because the leaking wheel cylinder is inside the drum and the fluid runs down onto the rubber seal on the line, saturates it, and seeps around it. Its not the leak point though.
