Porting service ?
 
Hi,
please help me with this:

I recently bought a superram that I want to port
could somebody let me know who can do this ?

only runners and plenum, tpi big mouth is already ported but the guy who made this job is not porting more.

thanks in advance

Came from Lingenfelter so it stands to reason that they have the program to port it.

The plenum doesnt need any work unless you hack up the runners & for most 350s its a waste of $. What are you building?

350, 195 afr, 280xfi cam
big mouth base already ported to 195cc
all the good dyno number that i saw and read about this combo have the runners and plenum ported , good for 5800-6000 rpm

I doubt you need to port the runners/plenum, just use a gasket and port match them to the base. The super ram plenum and runners should have no problem supporting a 350ci to 5800-6000 rpm with those heads.

My super pulls to my 6000rpm rev-limiter on my 355ci no prolem. If it was a high-winding 383 you night consider porting but for a 350 you should be good to go with just a little port matching of the ruuner to base.

I was really impressed with Chad Spier and the thread he did a while back.

Wish he was a forum sponsor and would cut us all "corvette forum buddy" deals. :D

That guy knows what he's doing.

Id have to search for pics but have butchered those pretty good to the point where the entry from plenum to runner was 2x2. Waste on a 350 though and a chit ton of noise/time.
If you want to improve it work on the inside turn a little but dont expect to feel anything;they really arent a restriction (flowed them on bases, by themselves, w/heads etc.
