Re: 1970 c20 l9h 6l90e
The Hooker swap manifolds will work and fit great

Re: 1970 c20 l9h 6l90e
I took a photo and then I removed the heat shield and tested fitment without it and it was closer to fitting but still no luck.
Here are the photos.... This is with the heat shield obviously. I have a loose bolt in the first flange to hold it in place, the rear of the manifold is sitting about 1.5 inches above where it needs to be... http://i1320.photobucket.com/albums/...ps5b472cbd.jpg Now here is a photo with no heat shield. It's close, but no cigar. All of the bolts are in, I started to tighten the bolts but the collector flange is binding on the upper frame rail from below. http://i1320.photobucket.com/albums/...ps195be4af.jpg |

those don't look different than the Camaro headers I have (2010+), I wonder if they are Corvette ? Here's some pictures of mine.

You are right, they are different, and from my research I think they are LS2 exhaust manifolds. Those Camaro manifolds you have look like they would work. Are you using the ECE motor mounts? |

Re: 1970 c20 l9h 6l90e
I am still trying to decide between 2010+ camaro exhaust manifolds or just buying the hookers. People are just asking too damn much for a pair of used exhaust manifolds ($150-$200) and I figure the hookers probably flow better.

Re: 1970 c20 l9h 6l90e
Go with the Hookers they come in different coatings as well

Re: 1970 c20 l9h 6l90e
So, I spent $141.25 on eBay for the wrong exhaust manifolds (That includes shipping).
I immediately listed them myself when I realized they would not work for me and sold them for $100 + $20 shipping. Paypal took their cut of $3.78, eBay took their cut of $12 the actual ground shipping charge was $44.45 so I recouped $59.77 from my initial $141.25 investment. So I only lost $81.48 on the deal. |

I believe the height of you engine is critical for everything to fit right too. I used the clamshell mounts which raise the engine up. It also made me have to use a high hump. BTW, have you checked into the LS-1 site or trailblazer ss site? there are guys that will sell manifolds cheap on there when they upgrade to headers. Good luck |

Re: 1970 c20 l9h 6l90e
When I got home from work last night the hooker manifolds were waiting for me...
http://i1320.photobucket.com/albums/...ps6cd17577.jpg Here are a few photos of them installed. They fit perfect with plenty of room to breath. I think they look pretty damn nice too. http://i1320.photobucket.com/albums/...ps3ec2a5c2.jpg http://i1320.photobucket.com/albums/...pse8ebe925.jpg http://i1320.photobucket.com/albums/...ps04ab9a0f.jpg http://i1320.photobucket.com/albums/...ps323563e4.jpg |
Re: 1970 c20 l9h 6l90e
I am ready to move onto fuel now. Is anyone running the stock tank behind the seat with an inline pump?
|
Re: 1970 c20 l9h 6l90e
Very nice, those are the exact exhaust manifolds I would have recommended if I would have seen the clearance issue earlier.
|
Re: 1970 c20 l9h 6l90e
Yes sir told you man they are great for swaps and they flow great! You can get the O-ring gaskets for the collectors from your local parts store I have the part numbers if u can't find them

Re: 1970 c20 l9h 6l90e
I got the part numbers, They were listed on the instructions that came with the manifolds.
Exhaust manifold to cylinder head gasket part # 12617944 Exhaust manifold to cylinder head bolts part # 11518860 or 11547135 Exhaust manifold outlet seal part # 92202326 Exhaust manifold outlet studs 10mmx1.5 part # 11589264 Exhaust manifold stud nuts 10mmx1.5 part # 15032594 All together about $155 from gmpartsdirect but I already have the manifold head bolts so about $120 |
Re: 1970 c20 l9h 6l90e
Anyone have experience with Holly billet inline fuel pump? Part number 12-700? I am thinking about using this, gravity fed, by stock in cab tank.

If you go this route you are gonna want to mount the pump inside the frame rail, not in the cab because it would be annoying. I have also seen several guys do the "in tank" pump mod but unfortunately I can't remember specific builds so I can't point you to them directly. In the LSX swap section is where you will find them usually in the "budget" builds. |

Re: 1970 c20 l9h 6l90e
The O ring gaskets actually cross over to Pontiac G8 and a few other cars like the Acadia but not a 2010 Camaro.. The studs are in the help section of most part stores
|
Re: 1970 c20 l9h 6l90e
This is looking pretty cool.! Love the shop truck look. It'll surprise a few people once the LS is up and running.
Thanks for the pics too. I have an LS swap planned in the future. |
