'67 GTO LS3 Swap

[ProdigyCustoms]

Thanks Ron!

Frank, nice car. Details?

The convertible has been a work in progress for a couple years. We had it for a while and did a "reverse frame off" without painting the car, added front and rear Speedtech coil over conversion. Installed one of Our Prodigy Customs Total Car G Machine Street Brake Packages with 12.19 (6) piston F and 12.19 (4) rear. We narrowed the original rear, added big Ford Torino ends and built the wheels. Then it went to Corvette Master and got a badd ass poncho motor and 700R. Now it is back to us for a freshen all over on the paint, then off to High Performance Pontiac for a feature shoot.

Colin's rear is a bit unique. Because he already owned his brakes for the original rear, we wanted to upgrade to the larger 3.15 Torino bearing, but kept the original bolt pattern. A coordination effort between Tobin at Kore 3 (Thanks Tobin) Prodigy and Moser and we figured it out.

If your starting from scratch and DO NOT already own your brakes, a Torino end is the easiest way to go.

Car looks and sounds great!

What did you use for bearing ends on the rearend?
What are the breaks?

Got the suspension mostly done. Still have to install swaybars and align it.





Still trying to figure out ride height. The initial height with the SPC springs had it slammed (in my opinion).









We raised it an 1.5" on the lift and I think that's where I like it. The SPC LCAs come with shims so the front shouldn't be a problem, but for the rear I'll have to get spacers.

[ProdigyCustoms]

Wow, Wow, Wow! Looks like we nailed the backspace and rear width. The deep lip makes such a difference on these cars. That is a really good looking wheel for that car.

[CFster]

I like them too! Thanks.

We've been going back and forth on the ride height. I though that in the first few pics it was too low, then Marcus sent me some scans of some old Pontiac ads - these cars really sat pretty low from the factory. I think it will be a compromise somewhere in the middle - the first shot of the car has only 3-1/4" from the front crossmember to the ground. And the AutoKraft pan sits a hair lower than the crossmember on the rear edge, so I don't want to take any chances.

Can't wait to get it lined up and drive it.

FYI, also have a Shrifter coming...

Wow, I can not believe that is the same car. Looks great. Thanks for posting Eric

[cspecken]

Looks really good!!! What size rim/tire combination did you go with and what kind of back space did you have?


Thanks

[CFster]

Got the ride height where I think we want it. Savitske's suspension is awesome - I think we're going to have to put some seats in it. I almost ended up in the passenger seat while cornering!

Very nice!

[ponchoblue]

great car what was the parts # on the front brakes how do you like the varishocks

[therobski]

new guy here, nice build/project. Been an Olds guy all my gearhead life, my 64 F-85 is going with a built 65 425. Can't get myself over to the "dark side yet"

[CFster]

Ok, this thing rides way too stiff. What can I do to soften it up?

[ProdigyCustoms]

What springs does it have in it? Try only 3 to 4 clicks in the shocks.

If you are running SC&C springs don't do any thing yet. I felt the same way right after I had mine installed but after a few miles they softened up and are perfect now and I ride on some pretty rough farm roads. FYI I have the same issue as you trying to stay in my seats. I put my 90 year old mother in-law in the floor board between the seats when she didn't tighten her seat belt enough. I was showing the family how well it cornered. The mother in-law thought it was funny but my boss in the back not so much. The car looks great !

[CFster]

SPC springs.

Backed the shocks down to 3 with no improvement. Mark at SC&C gave me a few things to check out...

[CFster]

Frank didn't sell me the suspension but he did sell me the rims and diff! And yes he does give great customer service.

[jy211]

He helps with the knowledge...

[CFster]

Found the problem. Took the front bar off and it rides much, much better. The Hellwig bar has a clevis type of end link set up, that can rotate in any direction then you tighten it down. I think what I should have done is drive the car, let it find it's spot then tighten it. Must have been binding and not allowing the bar to twist or something (resulting in a much higher spring rate).

Interesting.
