Thread: Will stock 5.3 exhaust manifold fit my 95 Z71?

    Will stock 5.3 exhaust manifold fit my 95 Z71?

    Hey guys just finding out the last bits of info for a 5.3 swap into my 1995 Z71 with the 350 TBI. I am wondering if the stock exhaust manifolds from a 5.3 truck will work out on this model truck. It does have a 6.5" suspension lift, dont know if that matters but would love to avoid headers as this is definitely a budget build. I saw where one member successfuly used the stock manifolds on his 95 rcsb 2wd 454 ss...Wondering if same body style but 4x4 will work too.

    Also wondering if my stock radiator (good condition) will work and if either my old fan or the 5.3 fan will work,,,Any help at all is greatly appreciated. Happy Thanksgiving and Merry Christmas to all.

    Edit: ALSO, wondering if the exhaust from my TBI setup will work given I install the 2 new 02 sensors. Its a 2.5" y pipe with one cat all the way back, no mufflers. Should work right? Long as I get a exhaust shop to install the new 02's? Once again all new exhaust would really break the bank on this swap, thanks again guys.

    the stock 5.3 fan and radiator should work and im pretty sure the manifold the same... the only thing in question is the o2 sensors i believe nelson performance can help you with that ...... i'm doing about the same swap (1995 chevy tahoe 6.0) i'm having nelson per rework my harness...and like you im using all my old stuff except radiator and fan(I got a radiator out off a 1999 chevy suburban @ harrys im going with the electric fans) hope this helps im still new @ this

    I used the stock manifolds on my 6.0 in my 92 k1500. With the adapter plates I made I was able to just have my exhaust modified to fit the manifolds. I also used my stock radiator but I used electric fans so I dont know if the 5.3 fan will work or not.
