Headers

[SierraZ-71]

I have and 88 k1500 350 Z-71. I just recently baught a pair of
Black Jack Headers for $150 bucks canadian brand new from a guy.They were never used even the packages wasnt open. I got them home i was looking at the installation manual and its said there were for a Corvette 1960-1980 small block 200-400CI. The question is will these bolt on and work. Quick response is needed thanx.

The bolt patern on the head itself should be the same, it is the frame, steering shaft, front driveline, transfercase and starter that are gonna cause some issues. Proper headesr are only like $200 for that truck

Lets Say By Chance they clear and line up right. Will i gain anything from these headers.

Dude, those are not going to work. Send them back and get the right ones for your truck. It would not be worth your time and effort to try to "make" them work, and you would probably do more harm than good.

Thats what i thought thanx boyz, now which headers would be best for my setup, true duals straight back 2.5" pipes into to 2dynomax super flow mufflers is what im running, should i get shorty headers or long tube headers. im kinda worried about back pressure.

From what I've seen & heard, long tube headers seem to be the best bet for 88+. Im not sure about the back pressure issue though. :burn:
