Has anyone used Dynatech 67-69 camaro Ls swap headers in 67-72 C10

Im trying to find a good fitting set of large tube headers for a 5.3 transplant in my 69 C10. I do have pol engine stands. I was wondering if anyone have used Dynatech 67-69 headers (part number 715-21410). I found a used set but dont want to waste my money and time if they will not work. Thanks for any info!

don't know how much different they are...but I am running their 2nd gen ('70-'81) LSx swap headers...other then hanging below the frame rails, they fit great and from my trucks performance they seem to make good power.

be advised...they run a unique 4 bolt collector flange.

When you say "large tube" are you talking 1 3/4.. 1 7/8... 2...


I have been running a set of Edelbrock 1 3/4 stepped to 1 7/8 since 2005. However, my motor is shoved as far back as possible and sits on a motor plate (used to sit on custom frame mounts I made).

I have been tryin to find a bigger set for myself.

The 1 7/8 trail blazer ss headers from kooks probably would fit my frame, and I could probably modify the mod plate, but the passenger side was all over my aftermarket 6 bolt head.

Super... are those 1st gen f-body headers or for trucks?

also Nohatch....thought the small/large tube headers were the sbc headers.
when I bought mine 1 7/8" tube with 3" collector was it...had they had stepped ones available I may have gone that way...

Heres an idea of the clearance using the kooks tbss headers. I do have a mild drop member but im certain they would fit very well with stock x member.
