Yes sir those are 18" iroc replicas, and I was letting the engine get up to temp and purging air out of the system.

Re: 89 iroc ls1/t56 swap
How did you get the old 5 speed indicator out so the 6 speed one could go in??
Random, I know, but I got a new centre piece from hawks and don't want to mess it up.

I believe the original center caps will fit in the replicas..and the 5speed emblem on the console I just covered it with a decal that hawks sells for the 6 speed conversion if that's what you were referring to.

Re: 89 iroc ls1/t56 swap
Thanks....Has hawks stainless headers and y pipe to a cutout right before back axle then goes through a flow master muffler..in video cutout is open... I like it you can really hear the cam that way I'll eventually get me an electric cutout valve for it. Been driving it around putting some miles on it and man I love it. My next thing will probly be suspension upgrades n maybe my boss's moser rear with 373's if I can talk him out of it.

Re: 89 iroc ls1/t56 swap
Man that sounds so good, I've seen so many LSX upgrades on this board and even one at work into a '95 S10. I want it but will have to wait til after the first of next year. Right now finishing some rear end and suspension upgrades. Everything else is ready just need the bucks for the LS/trans. I want to do a H/C/I with a 4L60E.

Its really not that bad if you have time to do it some how I got it done in 6 months give or take.. personally I think its ideal if u have a donor car..wrecked or whatever that way your not piecing it together.
