'67 GTO LS3 Swap

[cspecken]

I am going to be installing the same front suspension on my 64 GTO, and would like to know the spacer configuration you ended up going with?


Thanks in advance

Hi Chris.

I went with an aluminum spacer and two shims.

Glad that you found your rough ride issue, or whatever with that added extra spring rate....sometimes it's hard to isolate those types of things.

Killer stance..
Very nice GOAT...
LS sounds GREAT...

CFster,
I am in progress of a build on a 67 LeMans and I am using a LS376/480 with a 4L80E trans. I have a couple of questions if you do not mind:
1. Did you have any clearence issues of any kind using the AutoKraft oil pan? If so what did you do to correct them?
2. Can you tell me what weighed in making your choice to use SpearTech over the GMPP harness and ECU?

Thanks a bunch-Ken

Ken,

No clearance issues at all - with the stock steering knuckles. Once I put the AFX spindles on now the tie rods hit the pan at full lock (more steering lock than before).

You probably will have clearance issues with that 4L80E though. It's quite a bit bigger than a 4L60E. You'll probably have to modify the tunnel.

What weighed in my choice to go with SpearTech harness? Naivete? Inexperience? SpearTech does things like disabling the VATs, labeling the harness connectors clearly and builds it to length - plus just about anything else you want done. Now that I've done it, I could probably do the same with a GMPP harness and ECU if I do it again. I'm learning some things with HPTuners too.

Beautiful wheel and paddle shifter. Details please.

[CFster]

It's a Shrifter from Twist Machine, and a Grant #794 Corvette style wheel. 14" with a flat offset. The Shrifter is a couple inches deep so I made sure I changed to a flat wheel otherwise it would be in my stomach.

[Pontiacken]

What transmission shifter and control box are you using or going to use?

[CFster]

I have a 4L60E with Compushift controller that's been in the car for a couple years. The Shrifter is a direct plug and play.

[Pontiacken]

Still drooling over the new wheel and shifter! How long before you think you will get them in? Please post some pics.

[CFster]

May be a couple weeks. Some stuff came up at work.

Also, I was driving along last night and the fuel line popped off the rail. Sprayed gas all over the hot motor and exhaust. Fortunately it didn't burn down. Damned Russell quick disconnect fittings --> http://www.chevelles.com/forums/showthread.php?t=351873

[Pontiacken]

I am truly glad you were able to come away only wet and not flamming! Thanks for sharing because those fittings were on my fuel system list. Not anymore though.

CFster,

I started a thread today on my project if you are interested. https://www.pro-touring.com/showthre...mp-4L80E-Build

Car looks great Ken. Anybody can bolt parts on (like me), but a build with fabrication in a home garage always impresses the hell out of me (coming from somebody who can't weld to save his life!).

And, as feared I have the dreaded Spectra gas tank sucking air problem. As in Spectra SUCKS. After reading up on them on a few boards I can't believe they boned so many people.

I never really ran it down to 1/4 tank since the swap - going around a corner and it shut down on me. I had the tank for over a year sitting in a box, but of course didn't find out about the problem until long after I bought it. Just hoped I was one of the lucky ones.

Now I have to come up with a solution. There's no way I'm paying a G-note for a Rick's tank. Perhaps a Tanks Inc in-tank Walbro with fuel tray?
