there different, there are different headers that fit but they are shorties or there twice as much as these or more and there only mid lengths

BigShoe24 · 09-06-2011, 09:47 PM

Any idea of the length of the black line? Thanks

85burb · 09-09-2011, 11:33 PM

Do you have your body on yet? Was wondering if they cleared the shifter linkage.

from underneath, (sticking a tape up from the bottom) it looks like 18.5" - 19" max.

shrunken66stroker · 02-28-2011, 01:53 AM

Help me out with a measurement if you would. I'd love to know the height from the very top of the upper primary to the lowest point. Thanks

**Clyde65** · 02-28-2011, 11:14 AM

so flaming, they work on a square? or?

jhln8c · 02-28-2011, 11:33 AM

Are you going to be able to use the stock wire for cylinder #5

flamingbig10 · 02-28-2011, 09:09 PM

those aren't my pics there from a different site and not for sure if they really fit

flamingbig10 · 03-07-2011, 11:33 PM

I went a head and got some hooker super comp 64-72 chevelle headers

85burb · 03-08-2011, 12:36 AM

Looks like a good fit. Did you have to do any thing to make them fit? What mount plates you using?

flamingbig10 · 03-08-2011, 12:56 AM

I'm using the dirty dingo mounts around the stock position, I haven't had to do any trimming yet but I will a little on the the trans mission ears that stick out, On the passenger side the tube are real close to starter so I will use some type of heat there or and mini starter

85burb · 03-08-2011, 01:06 AM

That is the same plates i have! Look way better then the f body set i tryed. Thanks

shrunken66stroker · 03-09-2011, 11:55 PM

Wow. They look great. I just got an email from Speedway Motors saying they cancelled my order for the Dynatech 70-81 Camaro swap headers. They don't make them anymore and Speedway recently sold their last pair. I'll be looking at the Hookers for sure. They've got to be more expensive than the Dynamax. Where did you get them, flamingbig10?

shrunken66stroker · 03-10-2011, 01:03 AM

Wow, the Hookers are $300 more than the Dynatechs.

68GMCCustom · 03-10-2011, 11:15 AM

wow.....Dynatech dropped them? I just recieved one of their new 2011 catalogs and they listed them in it.

Dynatech also offers LSx swap headers for the '67-'69 Camaro's and the early (pre-'75) Nova's...and I think even the pre '73 Chevelle's, but I don't have the catalog handy.

shrunken66stroker · 03-10-2011, 11:56 AM

I haven't seen anyone use the other Dynatech's for swap in trucks. I'd love to know how they fit.
Jegs has the 70-81 Camaro swap headers with the 1 3/4 to 1 7/8 step primaries in stock for $400. I might just pull the trigger on those. The Hookers look great but I can't afford to drop $700 on them right now.

flamingbig10 · 03-11-2011, 12:11 AM

thanks, yes these headers were a little pricey but I need to get this truck so I got these

shrunken66stroker · 03-11-2011, 02:45 AM

Just bought the 70-81 Camaro 1 3/4 to 1 7/8 step to 3" from Jegs.

whats the part number of the ones you're talking about?

shrunken66stroker · 03-12-2011, 10:56 PM

329-740-29310 is what it says on the invoice. I'll post pics when they get here. They're supposed to arrive on Friday.

softballnrd27 · 03-13-2011, 12:37 AM

That part number says they are for a small block chevy

shrunken66stroker · 03-13-2011, 02:13 AM

You're right. I just called FedEx and had them turn the shipment around to Jegs. softballnrd27, I owe you a beer. You probably just saved me 40-50 bucks in shipping that I would have had to pay if they had gotten all the way to my house. Thank You!

softballnrd27 · 03-13-2011, 03:55 AM

Not a problem, I was going to get the steps too but when I looked at the part number it was SBC not LS. I have only been able to fnd the 67-69 part number but I don't know if they will fit or not. Good thing is that I have 6 months to wait.

68GMCCustom · 03-13-2011, 01:48 PM

several stepped ones are available for a sbc. Dynatech's available LSx headers are not stepped, and not painted...they come coated only, and for $399. Dynatech's SuperMaxx series for new/newish factory LSx powered cars is also available but they start at like $859!

Part#'s from the Dynatech 2001 catalog for '70-'81 Camaro are:
1 7/8" x 3" LSx coated header- #715-29410 w/3" reducers
1 7/8" x 3" LSx coated header - #715-19410 w/2.5" reducers

Part#'s from the Dynatech 2001 catalog for '67-'69 Camaro are:
1 7/8" x 3" LSx coated header- #715-21410 w/3" reducers
1 7/8" x 3" LSx coated header - #715-11410 w/2.5" reducers

Part#'s from the Dynatech 2001 catalog for '68-'74 Nova (same as 1st gen Camaro?)are:
1 7/8" x 3" LSx coated header- #715-21410 w/3" reducers
1 7/8" x 3" LSx coated header - #715-11410 w/2.5" reducers
