LS Swap systems that work with Ridetech Tru Turn system for 1rst gen Fbody

[Stovebolter]

Hoping we can get a thread going that can get people that have a Tru Turn system going in the right direction for LS swap system that will work for the 1rst gen F body.

Please list what LS swap mounts, header, transmission crossmember, and oil pan combinations you are using. List what modifications you had to make to get clearances.... if any. And your over thoughts on this system. Maybe we can help some folks avert some sleepless nights trying to figure this out. Lol.

I'll be doing the LS swap this spring. As far as the Tru turn system with the conventional small block drivetrain, mine works great. And this system is a very nicely engineered package. A very very noticeable difference in handling. I did have to alter the inner and outer fenders for tire clearance. And I did go with a 9.5" tire with 5.75" bs so I gained a 1/2" of clearance. JFYI.

^ great topic. I'll be doing the same next year. the advice is much appreciated.

We used the following on a buddy's 69:

*Small block GM engine stands (short/wide)
*Dirty Dingo DD 3 position adj mounts
*Holly Pan- 1st design (req shim eng stands 1/4" for x-member clearance)
*Mast pan requires no shims; should work w tru-turn based on rough measurements
*Iroc steering box
*Dynatech headers (these do hang low- id cut 4 bolt flange off & use slip-on connection w/ thin band clamp if the car will be lowered more than 2". Cyl # 5 & 7 plug wires will need some creative routing to keep them off the header tubes. MSD wires with bendable boots seem to work best
*Speed Tech trans crossmember - T-56 6 speed

We used Fbody accessories. The alt is very close to the frame in one spot, but with the shimmed stands it was fine. Will need slight clearancing without shimmed engine stands. We'll be using the C6 accessroies on that one.

That was the only tru turn swap I have done. I'll be doing another for a friend around march/april and will use the mast pan & try some other headers. This will be a 6 speed as well.

Ls3
Holley mounts
Holley oil pan
Hooker headers
Holley cross member
Everything fit great, wish the rest of the build was that easy

So all the new holley swap parts fit w tru turn? I had read they wouldn't work. Any pics? Scott

I used real simple parts on my own car, here's the parts and numbers


TALL 1969 350 factory engine mounts
#7-519 Prothane engine plate and mount kit
#20140 Moroso Pan and the correct pick up
#LS10 Sanderson Headers
#20-143 Holley Accessory Drive Kit
factory 4 speed trans cross member(modified the trans mount slots 1inch longer)
#TM32AN-T Tanks inc fuel tank, with internal pump

the holley system does work with the mid length headers. for there long tube you have to mod 1 tube on the pass side and there is a pdf you can download thats linked on the ls1tech thread.

A buddy of mine did pretty much the same setup on a build and not only did everything fit nicely it put the engine in the stock location as the original SBC. That made it nice for the TKO that was reused so basically from the bellhousing back everything stayed the same. Not sure how it would work with the Tru Turn though.

Here it is. an LS swap kit SPECIFICALLY designed for the TRU TURN.

Not sure what more you would want???
unless it is the T56 install kit?

that should EASILY answer the OP question I would think.
