Shorty Headers into a '71 Blazer?

[johnnywagon]

I'm going to be building a new crossmember under the trans near the front leaf spring shackles to deal with major frame tweaking (thats another story/thread) but in order to do this I will need to swap the standard full length headers for shorties. I dont think that the basic Camaro/Chevelle shorty headers will work, maybe late 80's early 90's truck headers? Anyone have any input?

Thanks!
