Can someone please tell me the measurement of the dougs d308 headers from the passenger side flange bolt center line to the to the upper most tip of the collector flange by taking a straight edge across the flange and out to the end of the collector and then measure up from collector. I basically need about 12 inches. I have ordered 2 sets of headers already and they both hit the floor. First it was the summit headers and then the thorley 376-y1 that everyone has had good luck with and thorley said was 13 inches but was actually 11. 376's touched the sub frame where the pipes merge into the collector, and the floor on the passenger side when installed. The Dougs look good in the pics. I realize this will only work off the car so I may not get a reply but I'm open to other brands as long as I get the 12 inches. Otherwise I may have to go with shorties but cannot get reliable performance data and everyone says go with long tubes. I know about the mounts but unless it will drop the engine 1 inch or more and to the left at least 1/4" I'm out of luck. I was going to bend them but figured patience would pay off and I would find a set that fit (not to mention 600 dollar pipes):noway:. Any recommendations that fit the meas. and would work with the combo below will be taken into consideration. Sorry for the long post but I'm frustrated and want to give all the vital info .

info:
68 camaro 350/th350 original stands, 2285 mounts new stock trans mount
originally 327/PG
patriot performance freedom series heads ( maybe causing problem)
xr276hr, 1.6 rr, 6.75 damper ,HEI dented firewall, performer RPM/750 edl
American thunder dual muffler kit PN?
new sub frame rubber bushings.
4x4 stock stance with new heavy coil springs
235/60/15 tires fr 275/60/15 rr

I'd take another look at the trans mount even though it is new. It wouldn't take much to tilt the engine too high if the mount is thicker than it should be.

How tall should it be? The one I got was from checker/cskauto

Good question, but I don't have the answer. I'm sure someone will before the day is out. I do recall an earlier post where the cross member was put in backwards which caused a problem because of the angle of the mounting point. Just something else to double check.

The angled portion of my cross member faces the back if I recall corectly, I will check when I get home. Thanks

When you say "2285 mounts", those are for a 327, right?

That is the anchor part number from cskauto. I went there yesterday and looked at the 2267 next to the 2285 and they looked identical in height and width so I did not get them. I was encouraged because I thought that may be the problem. I measured the frame stands at 2.52 pass and 2.58 drivers with a dial caliper. there is a gap on either side of the mount lllll lllllllllllllllllllllllllllllllllllllll lllll

about that big. I cant see it changing things that much though. I may be wrong

It's hard to get the right mounts from the chain auto parts stores. I had the opposite problem with the '69 engine being to low. Bought the "correct" mounts from Rick's which raised the engine where it needed to be. If you haven't already you should visit Dave's site http://www.pozziracing.com/camaro_engine.htm
With the original stands you need 327 mounts. Measure the thickness of the mounts you have, we can probably figure it out from there.

I would say, just the opposite. Your engine mounts should fit on your frame stands, with no gap. I use the energy suspension, tall and narrow poly mounts. It sounds like you have 350 frame stands. If the car was originally a 327, how did they get changed ? It also says that the 2285 and 2267 are both replaced by the short and wide mounts, which you say do not fit.

By raising the engine, you will put more of a tilt on it, as your transmission will stay in the same place, possibly allowing the headers to angle down, under the floor.

got the car when I was 16 10 years ago with a goodwrench 350. It had 327 on the side and the original (I think) 2 barrel manifold with the turbo fire 210 HP sticker on the air cleaner. I guesed the PO would not have changed the stands but I could be wrong. Where is the serial # located on them? I have read so much about it that I started to get confused. I have the 6 3/4 balancer for use with the power steering bracket so that is not an issue, bottom line is what combo of stands/mounts will get it lowest? 327 stands and wide short mounts?

Are the frame stands engine mounting bolt hole oblonged out ? If you have 350 frame stands and use 327 engine mounts... you cannot bolt both sides of the engine down, without some type of a modification. If you have 327 frame stands, the 350 engine mounts won't fit over the stands. The 350 package will raise the front of the engine while lowering the transmission to allow your headers to slide under the floor.

327 stands need short & wide mounts
350 stands need tall & narrow mounts

Tom did I get it right? I know you've set me straight on this once before.

What you're saying about raising the engine makes sense but it didn't work that way for me. I had 350 stands with short wide mounts (big gaps on each side) on the '69 which was incorrect and when I installed the tall & narrow the headers came up closer to the floor which in my case is what I wanted.

I still think the problem could be the fact that the chain store mounts are just not correct. There was almost 1" thickness diff. in the ones I bought from Advance Auto versus Ricks.

David, It wouldn't take much to try Toms theory just by jacking the engine up a bit and the link he provided gives you the measurements for the trans and engine mounts. I can measure the '67 (327 stands) or the '69 (350 stands) tonight if you need them.

Hey Robert, LOL :) You are right on, about the mounts. I learned the differences, the hard way ! My theory with the taller mounts, should do basicly the same thing as what you mentioned with the transmission mount. I have the Hooker Competition headers and the one side is almost touching the floor ! If I didn't have new poly body mounts, it probably wouldn't fit. -Tom

alright, here is the deal. The holes on the mounts 2285 are elongated, stands are not. I measured the dimensions:

Passenger Stands; 2 1/4" frame to bolt center,~2 5/8 inch wide Mount: 2 13/16 wide (cheap mount matches none of the ones in the link) 1 5/8 inch block to bolt center

Driver Stands:2 1/8"frame to center of bolt ~2 5/8 wide (but I think the ps bracket makes up the difference) Mount is identical to pass side.

Bottom line is both sides measure around 3 7/8" frame to block wich is right where it should be according to the link on mounts and stands. right? the energy suspension ones actualy are taller by 1/8".

What I did see is that I can lower by about 1 1/4" by changing to the hipo 69 stands that measure 1 7/16 tall pass and 1 1/2 driv and the 1 1/8 tall hipo interlocking mounts 2 5/8" total block to frame but will that mess up my drive shaft geometry too much?

I just measured the '67 and it's as close to 3 7/8 total as I can tell with a tape measure. I could pull out some better measuring tools but I doubt it would matter. So it looks like that part is okay. Did you check the trans mount / crossmember?

I checked the cross member and the three holes are on the drivers side. I think that is right. I have not measured the trans mount yet though.

I measured around ~1 1/2" for the trans mount height. Anyone able to measure their headers yet? I was looking at the 68608 hedman shortys but thought the may hit the fire wall.

Well, I got the thorleys to fit by replacing the body mount bushings that I did not do 2 years ago because I thought it was not worth the hassle. It gave me about 1/4" from the floor. the pass side is still about 1/8" from the subframe. Is this what others are experiencing? It is hard to tell from the Pics I have seen here. Another thing is my car hit something along the way because I saw a big dent on the pass side sub frame where it curves under the car and I think that is causing all the fitment issues, It may be teaked in and bent up making the floor lower as well. Thanks for all the help so far.

Glad you got them to fit. Thorleys are snug to the floor by design. I read in your first post "new sub frame rubber bushings". Which ones didn't get replaced to start with, just curious? A bent subframe is not the best thing, might want to keep an eye out for a replacement. Any how, when it all comes together it will be worth it. :yes:

I replaced the middle lower bushings, the ones that go between the body and the frame looked OK but maybe because it looked hard to do. I replaced those now and that seems to have give me the extra room. I just hope they dont hit the floor on the drivers side when I get on it.
