Project budget Crapice
New twin on3 70mm. Barely used (supposedly) 120 low z with a versafueler. Prototype intercooler from my friends shop that was about to get tossed. LS1 intake with stock truck throttle body. Speedinc tu1.5 cam, springs, pushrods.
Here is where I am at. Budget build using stuff I already have. Bought a couple bends locally..




Let me know what you think... Gonna have a whole lot of questions.

Thinking about not even using a dipstick, welding a fitting on the side of the pan, and using a sight tube. Get a plug for the dipstick tube hole. Could pump fluid in through there.
Project/progress looks great, but I'm a little pissed... I was hoping to have one of the first twin turbo 6.0/80e b-body cars in the midwest come next spring. lol
Just a thought...
Here is the plate I am getting.

Gonna drive it for a while and swap it all into a nice fleetwood or roadmaster.

For some reason I always thought of cutouts to just bypass the muffler. Did I say I really like your idea? How fast do those things open? How is yours actuated? With a pressure switch @ 1 or 2 psi? Which one you running?
2" should be fine? I imagine it only takes 75-100 horsepower to cruise @ 75-80? Thanks!
I run A 10:1 5.3 and 2" seems fine but I only run a short 5-6" length of it. If you plan to run a full system I'd maybe go 2.25"
I went with these guys. They have great customer service. They even have a 5" dump now.

I always liked this setup.


This is my whole exhaust system... Trapped 150mph with it in the quarter last weekend. With the dump closed it's quiet enough to have a conversation in the cab. I wanted to toss a 2.25" tractor muffler on it down the road.

Cut up the crossmember and rebuilt it with stuff laying around, including 1.25 electrical conduit. Not the prettiest thing, but it works.

Tried to modify truck throttle cable to work and it didn't. Got a fbody bracket from the dealer for $14. Slight tweaks and it works with the factory lt1 cable and truck cruise.
