I'm glad to be here as well. I'm a long-time and repeat squarebody owner myself, so I have more personal interest in the topics on this forum than what is present on any of the other sites I frequent in support of the Hooker LS swap kits.

Some Hooker pieces in place

Would love to know more about this.

The process is rather straight forward as long as you have fabricating abilities and equipment. You would start by installing your engine and trans in your truck using the Hooker engine mounting brackets and then jack up the rear of the transmission high enough to allow you to position the Hooker crossmember under the mount of the 6L80 trans. You would next adjust the height of the rear of the trans up or down until you achieve U-joint working angles that are optimized for your trucks' ride height/suspension configuration. Once that is achieved, you then need to design an adapter bracket that will connect the trans mount to the crossmember. If the crossmember crossbar is too high and leaves too little room for the design of such a piece, then you would just move the crossmember back about 4" and purchase/use the Hooker T56 crossmember cantilever bracket with the crossmember to provide a lower mounting surface height to build to.

toddoky, I'm having trouble figuring out which 2.5 exhaust fits my truck. It is a shortbed and I want the side exit exhaust.

Thanks,

Barry

This LS swap competition looks very interesting with a focus on the 73 - 87 C10.
Winner gets to keep the provided LS engine and Holley parts.

No problem!

Todd,
I placed a order through summit racing for the hooker exhaust system 11-17-15. Just got a email with expected ship date of 1-27-16. Does it really take 3 months to build a exhaust system?

I ordered my thru summit as well first of Dec . Summit did say its to ship in Jan when I ordered . I too just got a email from summit that they have not heard from the manufacturer on a ship date yet . So not sure when it will arrive . I would like to know if is going to be another month or so .

I would expect the holidays slowed things down . Also must of not had any stock at all on hand .

Yes, the holidays bring everything to a crawl for the most part...I'll see if I can find out something on the status Monday morning.

It depends on the actual kit you ordered...what tip exit style did you order, and did you order a 409SS or 304SS system. I bought a 304SS for my own Squarebody and had to wait a while as well to get it. I can tell you that either one is worth the wait as you won't find anything else available with the same or better fitment or hardware quality.

Thanks for the response.
I ordered the 304ss exiting behind the rear tire. No biggie, Im sure it will be worth the wait. I just assumed that you guys had several of these built up and ready to ship out.
I guess I'm just anxious to get it installed haha.

I'm hoping that this setup with the x-pipe will eliminate the flutter sound that I am getting when i get on it. It's been driving me crazy, I've tried different mufflers as well, they mostly just changed how loud it was.

I adapted the 2.5" version of that same system onto my 79' C20 and it sounds awesome at all road speeds and throttle angles. I'll see if I can find out anything about the status of things on Monday.

I got word today from someone in charge that your exhaust system will be shipping out shortly.

Toddoky-I am searching for headers that will fit my truck, it looks like these headers don't go below the frame rail. Is that the case? I want longtubes but don't want them going below the frame rail.

That's correct, neither the Hooker headers or exhaust systems drop below the frame rails when you mount the engine and trans with the Hooker engine brackets and transmission crossmember. Please note that the headers have unique bend geometry and will not install with typical flat swap plates that are use with the old-school type Chevy engine mounts.

Ok, I have the dirty dingo mounts that look very similar to the hooker mounts. I might give them a shot.

I'm glad to hear it...I saw them pop-up on an availability report the other day and knew they would be shipping out.

Toddoky , Well the exhaust came in and your warehouse shipped me the wrong one . I looked it up and it looked like it was for a 82-92 f-body ( 70501426rhkr ) . The one I am suppose to get was a 70501415rhkr . Called summit and they are sending ups to pick this one up . They had to place another order to process the 2nd one . The person said they will not be available to ship until middle of Feb . Can you check and see if you do have any available and if so could you expedite my order . I can PM you my name and address it will be shipping to also give you the order # . I don't want to wait another 3 to 6 weeks .

All is good . I am not upset , things do happen. I would like to get my truck back together .

Toddoky, I appreciate your involvement here so I bought some Hooker manifolds.

i have used those on a couple of swaps. They are very nice parts and fit many swap applications.
