4.3 Vortec Longtubes

[gmoutdoorsman]

Was given a set of heddman longtubes from an older (TBI) 4.3, I believe they should bolt right up with new o2 bungs. they were s10 model and my truck is a 1998 1500 2wd 1/2. How hard would it be to put these on?

If they were originally for an S10, there may be a few clearance issues. I'd be doing a bunch of measuring before I'd attempt this. Lot a work to get things torn down to install them, only to find that they won't fit.

yea i thought that also. Think its possible to cut them down to mid lengths and weld new collectors in? i was thinking that would help with clearance and also i may be able to reuse my y-pipe/cat with modifications of course
