Headers/mounts

OK, read everything, and everyone says "you have to usse *** brand plates and yyy brand headers" Problem is, they're all different!

Does anyone have an LS in a car that has retained the A/C box?

I also see a lot of references to moving the motor around "til everything fits"...how exactly? The typical plates appear to go on only 2 ways, mount to the front or mount to the back of the plate. I see the S10 mounts are slotted, is this what people are using to adjust positioning?

Here's what I'm considering, based on the posts here and at LS1tech.com (which will not let me activate my account, for some reason :x )

5.3/4L60E
S&P/Trans-dapt/Carshop plates with OE frame pads and shells
OE truck pan with 2" sectioned to minimize dragging
Camaro manifolds or headers

Probably going to have to use a cowl hood for clearance, then I'll be like every other G body :roll:

Anyone else have input?

It was my impression that pushing the engine back aggravated the A/C box problem.

Not really sure why John's mounts are triple what everybody else sells for, and there's no pic of them other than the "prototype" set, which didn't impress me.

ATS link doesn't work, links to front page, but I've seen 'em before. Look like the S&P, etc etc etc plates. Carshop has 'em cheapest, I believe. No need to pay for mounts that I'm not going to use anyway, I want to use the OE pads/shells.

From what I found, John's mounts are $175 +$15 to ship, and requires a notched F-body pan ($250, and you have to have a core) and the OE LS1 car mounts, although the truck pan might fit as well, aside from the depth issues. I read where one guy took 2" out of the truck pan to alleviate the scrape problems. May go that way, buddy has a killer heliarc machine..old school water cooled from the 30s/40s.

Could go Moroso pan, but like everybody, looking to spend as little $$ as possible to get a reliable setup. Doesn't look the greatest, either, IMO.

My biggest concern is the A/C box...not gonna do without it.

Also seems that you need to drill one hole in your crossmember to install.
