Here is a thread on LS1tech with a bunch of fitment info on the Tru turn and the new holley engine and trans mounts. Hopefully it will give others an idea of what oil pans, motor mounts and headers can and cant be used with the tru turn setup.

Question for Ridetech. What pitman and idler arms were used when you measured the bump steer? Stock my car came with two different length arms as did most 69's from what I can tell.

Thank you very much for all the detail you put into these posts. I wonder how the mid sized headers would work instead? Do you think they would still be in the way?

IT APPEARS that the Speedtech Ls headers will fit with no issues. I am just checking today if the ATS oil pan and our new frame stands for the engine mounts will work also.

Are the speedtech headers being produced again? I think the mid length headers would fit without a problem from what I have seen. Todd from holley may be able to confirm.

Very intersted in hearing your results, is that on a stock subframe our your subframe?

The new Hooker 2473-HKR headers will clear the Ridetech Tru Turn. Take a look at this thread:

18x9.5" with 6", excellent! and having a spacer or many spacers is a good tuning tool also, I use 2 spacers (0.095 in.each) 2 each side of my 9.5 rims with 5.5 back spacing to adjust turn-in (i think its called scrub radius) I dont really know, I do know on my camaro if I want a tighter turn in on certain tracks I remove both spacers and the car turns in faster like a beast almost twitchy...but faster longer tracks I add spacers as needed to slow down the turn in, for me...its a quick and dirty way to adjust so steering without changing toe-in or camber

Got any pics or videos of those real world 69's with the tru turn?

That is on a stock Sub frame. looking at the pictures the headers are nowhere even close to where the steering would be. the only question I need to answer is if the ATS oil pan will clear the truturn components and I will know that in the next couple days

Hopefully my wheels will be here soon so I can get them mounted up to see what mods will be needed to get them to fit. I'm also waiting on Speed Tech to see how there parts work with the Tru Turn before I order anything. My 570 horse LS3 should be here from Texas Speed tomorrow and I am talking with Bowler Transnmissions about getting an order together for a T56 and everything else needed to get it installed. It is amazing how quickly you can spend money on these things!
