anyone run the current performance LS conversion harness for these trucks? I acquired one for mine that plugs into the firewall and retains factory gauges. Seeing if anyone ran into any issues.

Yes i have a current performance harness for mine. Had a few issues had to send it back once to get it fixed. The problem was i had a 92 typhoon and they use a 93 harness the had there i believe. I sent both harnesses bad to them and they fixed in no time at all. Also sent me a check for the shipping it back to them. All in all i would use them again.

Are you having any issues with your harness?

Re: LSx SyTy Swap Information

Thinking about this swap. Will a swap from a truck clear the hood with the tall intake manifold and will the truck accessories clear if the short intake from a car is used.

Yes on the intake part, and the truck accesories should clear, it's more of what might hit the steering box kind of thing. If oyur running a/c I went with the high mount, but I would suggest notching the frame to keep the factory a/c down low. Makes for more room up top later on for a air intake set up, unless you want to run it to the drivers side. The engine compartment gets pretty full on these things. You going turbo or n/a?

No the GTO stuff didn't clear, but they did it the 62 Biscayne. Oil pan is a modded h3 hummer, exhaust manifolds are custom stainless. I bought 2 sets of different manifolds, cut them up and welded them together. Complete 3 inch stainless exhaust ( single exhaust) not dual. RPM mounts didn't work and neither did the cross member, bought a new harness and repinned it, stock rad with corvette fans and custom cold air intake, the filter is down low behind the drivers headlight,.

Re: LSx SyTy Swap Information

I have a very stout 700r4 and don't want to swap to 80e and all the things that need to be done.

cant I just buy crank spacer and kickdown cable bracket and mount it to a ls engine? do I need a special flexplate from a certain year truck 2wd or 4wd?

Did lots, trick flow heads, trick flow pushrods, roller rockers green top injectors. Also note I pulled the valve cover today and one of the rocker studs is broken and a push rod is bent. So much for car craft this weekend.

Trans tunnel modification should also be added to this list, I was actually surprised at how much a couple inches of lifting the trans/transfer case dug into the tunnel.

only need to do it if you are going to a 80-e, 60e or 700 r4 doesn't require it. So not really mentioned.
