What can i use for a L69 manifold??
hey, ive looked all over and i cant seem to find an exhaust manifold for an 84 T/A w/ an L69. i was just wondering if i was informed correctly, i was told that the L69 manifolds had larger outlets then that of an LG4. i looked at gmpartsdirect.com and various other online stores. i just want to afferm that the manifolds are diffrent from a L69 to a LG4.
Thanks

Yes the L69 manifolds are bigger and flow better than Lg4's. I think the size at the collector is 2.25 inches for the LG4 and 2.5 inches for L69. I also think that TPI maniflods are the same size as the L69.

The L69 manifold outlets are larger than the LG4. The TPI manifolds have the same size outlet as the L69, but IIRC the emission pipe is facing a direction opposite the L69. Also, the TPI manifold won't have the heat stove on the driver's side.

The higher HP 5.0 TPI and 5.7 TPI used the same exhaust manifolds as the L69. The lower HP TPI 5.0 used the smaller ones.

Interesting. I was under the impression TPI's, in general, were equipped with the larger manifolds.
