Dynatech MuscleMaxx Headers

[shrunken66stroker]

The problem is that Speedway Motors is out of the 70-81 Camaro swap headers and the only other place I can find them is Jegs for $719. Do you know of anywhere else that has them for $399?

[68GMCCustom]

Summit sells them for $399 and lists a 4/13 ship date if bought today.

Thanks man, I would appreciate it...

[BigShoe24]

Thanks, thats would put me flush with the bottom of my frame rails if measured from the top of the exhaust ports.

Did I read you were interested in selling them?

big shoe, if you have a raised crossmember or [dropmember] they will hang 1.5" below the frame.The only way I can see around that is to open the tunnel up to decrease the angle.My output shaft angle is at 3 deg. down & the trans is pretty tight.The headers are first rate anyhow.

I will be....when I can afford to buy a set of the DT large tube 67-72 LSx headers (they fit better with my long range plans) I'll be selling these Dynatech's.... unless I buy something else to put them on.

[68GMCCustom]

here's how they look on a stock truck w/engine at roughly normal (for an LSx) height.




I plan on a complete coil over IFS at some point...meaning I'll probably need the clearance the DT's provide.

mac72, thanks for the input, bud.

[mac72]

Your welcome,my clips off so if you need any measurements or pics let me know.I was sceptical about purchasing them at first because of ground clearance issues until i found that they are higher up than my pan.Just something to consider

[dkauffman05]

I can't seem to find the headers 68gmccustom used does anyone know the difference in the 67-69 camaro ones? I really wanted to use these but summit's website says not available.

[BigShoe24]

Mac, they are higher than your pan? How tall is you pan?

7.5" at it's lowest point.It's 1 of those GM conversion pans

[dkauffman05]

Found the 715-19410 and the 715-29410 both thinking about the first ones due to only having a stock 5.3 and the smaller tubes might give me more room.

[BigShoe24]

Ok, so the DT Big Tubes don't fit. Passenger side hits on the firewall bad. I'm placing to links below, could you confirm 68GMC these are what your running?

Might have to click on LSX on the second link.

Thanks

those on the Dynatech page look like the ones but it appears they changed the part number as they were 115-909400 (30C) when I bought. Also they're not stepped, just straight 1 7/8" primaries x 3" collectors. The Summit pics show stepped and #5 cylinder passing over behind #7....unlike Dynatech's pic.

I found out you can not go by pics on the web to determine what they are selling you.

very true!

[BigShoe24]

Anyone want to swap?

[68GMCCustom]

can't BigShoe....notice our posts above were changed with some words deleted? I guess maybe so, since now it shows you as Premium. I did that for a few years until I felt the site was large enough to support itself.....now I refuse to.

sorry.

[BigShoe24]

Kurt,

No worries. I went ahead and ordered a set of the Dynatech's. Hopefully I can sale the DT's and the Dynatech's will fit!

[68GMCCustom]

Good luck...I hope they work out for you.

[dkauffman05]

Ordered mine yesterday coming direct from dynatech

[BigShoe24]

dkauffman, really? I called and emailed and didn't get a response. I am always dumbfounded why more manufactures don't sale direct. I just hope get what I ordered and they fit!

[dkauffman05]

They got here today. I ordered 715-19410 from sumit and they were drop shipped from dynatech in 2 days. Summits website says $55 to ship them and I asked my salesman about that and it was wrong it was only $9.50.

[BigShoe24]

They worked!
