Cadillac CTS-V - Picture of my manifold situation

I was wondering if the guys in this section would know if the CTS-V manifolds are shorter height wise than the truck manifolds. Here's the situation I have:

And I can't tell by looking and can't find measurements to see if the CTS-V manifolds would give me something I can work with.

This is going in a '37 Chevrolet 4 door.

Thanks,

the stock v1 manifolds will tuck in a little closer than that to the block. i can take a picture of mine in the morning when i get home. Also you may look into the v2 stock manifolds, i believe i read in the swap/hybrids forum section that they are the most tucked( closest to the block) of any of the lsx factory manifolds.

Thanks for the reply. What are V2 manifolds?

I appreciate the measurements. I haven't found any online that show the distance from the block to the outside of the manifold. I borrowed a set of GTO manifolds that a friend's uncle had and they weren't even close so now I'm really skeptical of just buying a set without close measurements.

Thanks,

^^ V2 is 2009+ CTS-V's with LSA engine.

Here's a shot of a V1 driver's side manifold.

The outermost flange measurement is a touch less than 5" and the outermost pipe measurement is ~4.125".

The pipe flange is also higher than the truck manifold's pipe flange.

Another option to look at would be C5 manifolds.

Thanks for the measurements and pictures. That looks like it definitely work. I guess I'm going to be going with Cadillac manifolds. Is there a significant difference between the V1 and V2 that I would want one over the other, besides physical shape?

Thanks,

Look into 2006-2012 Corvette LS7 Z06 manifolds. They tuck in very well, and will provide more power than the ctsv manifolds.

More torque would always be good, but I'm just running a stock 5.3 that I changed to a single plane intake and will have an accufab 4150 (or comparable edelbrock), so I'm not sure I would flow enough for it to make a difference.

I'm not sure, just from looking, that the Z06 would solve my problem because the flange seems to be lower than the Cadillac, unless it tucked in so tight the flange fit between the engine and framerails.

The V2 manifolds appear to be very close, if not identical. There is, however, a big difference in the V2 pipes from the manifolds back.

The biggest difference will likely be cost. For some reason, the V2 manifolds seem to command a higher price.
