67 Skylark Convertible

Fired up but I am sure the intake is sucking air. Starts and stumbles but will rev. Pulling it tomorrow. Only a couple of things with the harness I wish were a little different is where they split to the opposite banks, make the split about 6 inches closer to PCM. A little tight on one side or the other. I would rather there be a little slack in the rear where it can be hidden, but it is still a very nice piece and looks super clean tucked under the injectors. Almost looks like there is no wiring on the engine.

Finally, so took the intake off today and sure enough it was not sitting on the heads fully. The valley cover bolts were holding the bottom of the runners off the gaskets. Cut about 1/8" off the head of the bolts and reinstalled everything. FIRED RIGHT UP and ran smooth. Exhaust has a really good deep throaty sound for being an off the shelf Summit kit with their brand mufflers. Going to keep plugging away and get the rest of the wiring done and dash in it so hopefully this weekend take it for a little drive.
Sorry for the poor video quality, I took it as a text message.

Congratulations! Amazing how nice that feeling is. All the effort is finally paying off. Sound good, glad to hear you are happy with exhaust, I hate spending time and money not knowing if you'll be happy or let down.

I have the ICT Billet adjustable mounts already. Just want to make sure I have the right mounts before I drop it in. Right now, I just have the stock 310 Wildcat mounts in there. But I don't want the 4L60E jammed up against the firewall either.

If you scroll through I believe there is a photo of the firewall clearance which was about 2.5" on passenger side and still had a ton of room for the tunnel. I took the set that was originally on the frame and cit the buckets down and tried them but he didn't like how low it sat so ordered what he thought was right which moved it to far forward so the Mast pan just touched the inner tie rod ends. Headers not fitting was another issue but ended up with manifolds anyway.

I'm doing the same dash swap in my 66' Skylark now. I made mine just like yours. I'm going to try and wire it up, but I don't know what wires are what from the factory speedo pigtail. Do you have a diagram of how you wired yours up? Thanks

Go to Lt1swap.com under wiring harness info and choose your year. From there you will find the pcm pinouts for tact and Speedo, assuming you are using GM electronic transmission. For water temp and oil pressure, the dash came with senders. Fuel level was tied to new 18 circuit vehicle harness.
