I also bought a FelPro gasket of the same design but for a 3" diameter exhaust. I may make another set of flanges with the 3" hole. I only bought them becasue I thought they were the correct ones but couldn't get the dimensions. Not cheap at $18 each so I'll see if I can make them work for a 3" exhaust.... |

Re: Stock Manifold Options for LS Swaps
i went to my local napa store for the gaskets and exhaust studs and nuts.
studs and nuts are the same without the hex end on the stud. and i did cut off the factory LM7 y-pipes and they do fit TBSS manifolds.

Re: Stock Manifold Options for LS Swaps
How thick are the flanges on the TBSS Manifolds at the head?

Re: Stock Manifold Options for LS Swaps
I tried to order a set of these online through one of the online GM parts suppliers,and after the order was processed,was told that the left hand manifold #12600526 was not available,with no date for availability.Following up,they tell me it is most likely that the left TBSS manifold has been discontinued.Being that these manifolds was used on a fairly limited amount of vehicles it is likely that GM will just sell what is left,and that will be it.The right hand and heat shields are currently available.
Dorman has an aftermarket manifold,appears to be the same,but is more than double the cost. |

Re: Stock Manifold Options for LS Swaps
I'm looking at buying an 04 2500HD with 6.0/4L80E. Will the stock manifolds on it not fit my '73 C20? Can a little clearancing be done? Probably going with the Dirty Dingo sliders, no AC.

most are using tbss manifolds camaro manifolds or headers. from what i understand there needs to be come frame cutting to make the stock manifolds work. they ARE wide. i dont like the idea of cutting up an original short wb frame. |

Re: Stock Manifold Options for LS Swaps
It really depends on exactly where you place the engine. In my '86, I used the stock truck manifolds and only had to trim a place in the passenger's frame rail about 1/2 inch "deep".

Re: Stock Manifold Options for LS Swaps
1/2" is significant trim, but I suppose I could add a little reinforcement to the flange (and maybe the web too). Where did you place your engine?

Re: Stock Manifold Options for LS Swaps
Not sure if this is common knowledge but the 2012+ Camaro ZL1 exhaust manifolds are stainless steel versions of the common 2010+ Camaro SS manifolds. Headers are a common upgrade on ZL1s so you can usually find low mileage versions around the web.
