Wondering if they are too restrictive for a 800rwhp build.

 

They will be fine, go for it !!!
All the LS manifolds are pretty good except for the FWD 5.3 stuff.
I used CTS-V manifolds on mine only because they fit my car better, but they are very similar to the vette manifolds.

Hey Jim, how is plug access, and are you running stock size plug wires?

 

I have the fwd 5.3's (LS4) on mine. They look less restricive than the c6's thats why I asked.

 

My car made 800 rwhp with a stock bottem end motor and c6 manifolds.

 

Hi John,

Plug access is awesome, I can swap the plugs in less than 10 minutes !!!

I made a set of custom length Taylor 10.4mm wires to allow me to relocate the coil packs to the bottom of the firewall on each side.
The cts-v manifolds would be too tight for the coils to stay on the stock brackets.
I preferred the old school look of clean covers anyways.

 

Wow that looks amazing, makes me wish i didnt build tubulars hahah

Thanks Jay

I just wish I had more time to play with the car,
it always seems to find its way to the back burner....
I'm switching to BS3 now, so out comes the stock pcm, harness, driver, 2-step.....
