Thanks man. Tracks are closed for the winter now so it won't be any time soon, but hopefully I can make it happen next spring with some fresh tires. Do you have a build thread?
I have not started a build thread yet, but I have been taking a lot of pictures so I may start one soon.
I am considering running the same headers as you, are you happy with them so far, other than the coating?

Yeah, I've been very happy with them but I don't know if they're still available. I think I remember reading that Edelbrock discontinued them as part of their downsizing. But that's been a while so maybe they've started producing them again? It's worth a look I guess.

In my '73 with the 4.8 that I put in I have the bellhousing flange about 3/4" from the firewall with no clearance problems with the Stainless works headers.

The mounting flange on the LS series engines is farther back on the engine so if you put the mounts in that spot it will move the bellhousing flange forward from your stock SBC or BBC location. So when they say 1" setback it means they move the bellhousing flange "back" to the stock SBC location.

I think I get what your saying. It sounds like the point of reference for set back is the motor mount's position on the LS block relative to factory SBC/BBC. Good enough for me. All I know is these ones work/fit well!

THANK YOU for that explanation. I had always wondered why what everyone calls 1" set-back mounts seem more like stock location to me. Makes perfect sense....the manufacturers could save themselves and customers a lot of grief if they would simply note that information.

No, haven't seen them yet. Do you know of anyone that's used them with any success yet?

The mounts an crossmembers are out for the early 2nd gen ( 70-74 ) but the headers are to be released in a few weeks, the headers and mounts have been out for a while now for the late 2nd gen camaros and there's a few guys over at Nasty that have them and Love the way they fit and ground clearance, its a complete match setup, Headers, eng mounts an crossmember .

I just want to let the OP know that my buddy and I are doing a LS swap on his 81 and I am using this thread and your car to set us in the right direction. I did my LS swap on my S10 so that will help too but this will be SOO much help. Thank you

Thanks guys for the kind words. I'm glad you're enjoying the thread and finding it useful. I wish I had more to update here recently but unfortunately I have to give my 99 TA some much needed attention over the winter.....and none of it is gonna be the fun stuff (nothing to make it go faster :devil). I'm planning on doing the first four legs of the Hot Rod Power Tour with it this summer so it needs a good cleaning, some general maintenance, plus it has a few lifters acting up. So I started tearing into the motor yesterday morning. The Camaro will probably sit until spring when it's time to throw on a new set of tires and fresh bottle and get back after it.

Gary,
Hopefully you can get some ink from the powertour. I've heard good things about Brian Toolely Racing's SLD lifters. Might be worth investigating.

Yeah, I'm hoping maybe the TA will be in the background of a few shots when they start snapping pics of Tony's (tsnow678) Camaro.

I have a set of them on the way. Ordered them from Speed Inc last week but they are shipping direct from Tooley. I'm hoping they'll show up early this week.

The only pics of my car will be in the shadows of the 99 after you embarass me in the quarter. You are a much better driver than I. Worse case we bench race and have a few beers and talk about how fast we are.

Now that's what I'm talkin about! I've never broken any (car) parts drinking beer and bench racing!

Hey Gary, when you mounted your MSD on the firewall, did you have to get an extension harness, or did it come with everything you needed?

Hey Darryl, no extension harness needed. The box comes with it's own harness and it was plenty long enough for where I mounted the box.

Gary,
Did you ever get those SLR lifters? I've seen them at Speed Inc before, but also knew BTR has been sold out for a while. I always wondered if Speed Inc stocked them or dropped shipped as you mentioned.
