I have a stock 350 tbi in my blazer now and I had to cut the exhaust off to fit my turbo 400 crossmember so now I need to have my exhaust re-run. I have a set of headers that will fit my blazer hanging on the wall in my shop and am debating rather to put them on or stick with the manifolds. I have headers on everything I own and know what a headache they can be. I am gonna use my blazer for mostly rocks and hill climbs not really any high rpm stuff. The only reason i im asking opinions is that I am at a point where it would make sense that if im gonna install them, now is the time.
