Thanks for the help n info..ur cutlass build is exactly what im planing on doing. Only thing is that i purchased the Holley alt/ps bracket hoping to get that "lsx" look. If i cant figure something else i will have to go your rout with a truck bracket. Thanks a lot for the info and great cutlass build.

Im sure im not the first and wont be the last to hope for the exhaust kit be available with or without mufflers. Could it be possible if enough customers ask for it?..maybe pass the word to those who could make that possible?
Kinda like with the accessory brackets. The option with or without ac compressor and alternator. Giving the customer options to re-use there existing items.

Actually, in all the preview threads I've created you are indeed the first to make such a request. I'll pass it along, but I don't see anything becoming of it at this time. With Hooker having 32 specific part numbers available for the G-body, I can make a fair prediction that no other company is offering the customer more options than we are.

I will snap a few pictures tonight if I get home before it's dark out. As for transmission, 4l80e. Ground clearance is actually pretty damn good . About level to your set of headers. Only cut I had to make was the passenger side for one primary. It wasn't too difficult but I understand if people do not want to cut the case. I did and even used it as a core with no issues.

I'm looking forward to seeing your photos.

Todd,

What is the intended crank/output of trans angle compared to the frame rails supposed to be?

Nominal 4 degrees when referenced to the frame

The changes made have provided better fitment on both the cars and I'll I can say regarding the build tolerances of these cars (and all others built in the same time period)is...holy crap. For those of you interested in the minute details of using these parts in your swap, I've formulated and attached a tech data sheet (PDF file at the bottom of this post)that pretty much lays it all out for you. It's 6 pages long, so crack open a bottle or two of your favorite brew and dive in. Here's the photo results of the last test fit session...all the important characteristics such as ground clearance and A/C box clearance are represented.

Yes, they are the 1-7/8" silver ceramic mild steel version of the headers.

Great, you wouldn't happen to have pictures of the headers outside of the vehicle? I want to get a better look at the merge and collector. also do you recall if they have the velocity spike in the collector?

You can find an image of the stainless headers, which feature the formed merge collectors on the summitracing.com website under part number 2333-7HKR. The stainless headers also feature collector spears as where the mild steel versions do not; standard canister style collectors are used on the mild steel headers like you see in the install photos here on this thread.

You can get a 700 series (also called Z65) box off RockAuto for $112-140 depending on what brand you buy, and that includes the core charge.

You can run F-body accessories as long as you run a 700 series steering box.

Yes, please do. I've read your build thread to familiarize myself with your component combination and will be able to provide details of the differences of these two approaches for those who are interested and following this thread for technical data.

No, I don't have any involvement with sales related activities or decisions at Holley.
