'67 GTO LS3 Swap

Love the coil covers. That definitely gives the engine compartment a "finished" look.

Thanks Colin!

So, I got these bolstered seat foams from TMI Products. They look great, but now you have to be a midget to fit in the car. The cushions are a LOT taller than before. No good.



So, i tried some Procars. You can see how much lower they are. They're nice, but too tight around the thighs.





This week I bought a set of 04-06 GTO seats on eBay. They're in really nice condition. I'm sure mounting them will be a challenge though!

Those seats will look great and are really nice. Too bad Chevy never made any cool "Nova" seats .

Were those the vinyl or leather pro-car seats? They look nice. I keep going back and forth between those and the Corbeau sport seats.

Thanks!

Colin,

If you are just doing the front GTO seat conversion it is not too bad. I am no expert by any means but if you have not look at my thread toward the bottom of page 5 and you can see what I have done. What I have not finished on the fronts is the rear mounts for the seat tracks. I should be getting the brackets I had made this week or next week. It was one of those favor things so I have had to wait a couple of months. Good luck! Ken

Those were the vinyl ProCars. Our intention was to recover them to match the rear at some point.

Ken, how low are your front seat cushions compared to the OEM seats?

Thanks,

Very nice build... The GTO seats are more of a one size fits all where those ProCar seats are more tailored to a person that is not my size. I would have to get a factory seat like the GTO as well.

Colin,

Well I am not sure as the factory seats have been out for years. What I can do is measure from the floor pan up to the cushion and give you that. By feel they do set higher than the OEM and that was the biggest challenge. Some compromise had to happen between where they felt the best to me vs. how high I am going to have to put the rear brackets to ensure unimpeded travel and adjustability. Both front seats are still out of the car from the rear conversion but as soon as I get the rear brackets in place and I can give you good hard measurment I will do that.

Nah, no need to do that. I'm fitting the seats already. I'm trying to get them as low as possible. The biggest challenge is the rear brackets. There's kind of a hump in the floor in the middle so if I put them all the way down the the seat motors will hit the carpet when I move the seat forward.

Yours look great. If I do decide to do the rears I'm sure I'll be calling on you for advice!

Yeah the ProCars are for somebody with a skinny ass and spindly legs - that's not me!

[CFster]

The passenger seat is bolted in.

Bracket modification:



Just a little tall (for me, I'm a big guy) but doable. Have to see how it feels down the road. They go way back though - you can see how far up the seat belt real is. I can stretch my legs out almost straight.

That trim piece on the side that holds the buttons is actually the lowest part of the seat itself. It's basically touching the carpet. It could conceivably be trimmed if we were to lower it any further. We had to space up the rear of the seat because the floor has a hump in it directly underneath, so it was kinda teetering on it. The driver's side seems to have a flatter floor - perhaps we can get the seat a hair lower there.

subscribing....love the build.

[Pontiacken]

Colin,

I need to order an accessory drive and you had mentioned Pace having one that came without the AC compressor. I will be using Vintage Air as well and so I was wondering did you get your accessory drive kit from Pace and if so do you still have the part #?

Thanks Ken

[CFster]

Ken,

Yes I did get the kit as you describe it from Pace. I'll get that part number for you when I get back to the office in the morning. I also used a Kwik bracket for the A/C compressor.

-Colin

[CFster]

Here you go Ken. Part #19155167 --> http://paceperformance.com/i-6485405...7-engines.html

What was confusing is it looks like a GM number, similar to their full accessory kit. However, this is a number that Pace came up with after they modified it.

Also it looks like the price went up about $110 since I bought mine in '10.

[Pontiacken]

Thank you Sir!

[Pontiacken]

Colin,
I just sent you a PM. I have a question about that tube and sensor going from the side of the throttle body then over the top to the pass side head.

Thanks,
Ken

Hey there,

Tim at TMI Products over here. Quick question for you...did you replace the frames and foam at the same time? If so, they will sit higher than an original, worn out bucket seat.

I'm 6'1" tall and in my 66 Chevelle with buckets, I've always been too tall for it. When I got the car it had worn out upholstery and I was too tall. When I had them reupholstered at a shop they were super firm and I sat super high. When I redid them with all of TMI's foam and upholstery I sat lower but my head will still barely scrape the headliner if I'm sitting upright and not slouched.

I've been meaning to do some surgery to the seat tracks and lower them. Plus I don't like how they don't get back far enough so I might just get a different set of tracks all together.

BTW, You have one of the nicest GTO's I've ever seen. I think I'm in love.

Tim, the frames were OEM. The foams came from you guys. I'm a big guy (6'5"), so even if I had just used stock foams they probably would have sat too high for me as well.

We made some brackets for the late model seats we put in. Lowered them basically until they're touching the floor, and they go waaay back so legroom isn't a problem.

Thanks for the compliment!
