porting

Just bought a new Dart Tunnel Ram. Is it worth having ported/polished at CFM Performance before install? 572 @ 6300rpm

What's up fellas? I needed some opinions on porting a Holley Strip Dominator intake manifold. This is currently the intake that I have on my boat along with a 750 dp Holley. It's a 454 .30 with 049 that have been ported a lot! I'm not sure What they are flowing or what the maximum airflow you...

What are you guys using as a porting area? Ready to do something different. Was thinking of several different design's but thought I might get some good feed back, tired of the mess. Thinking of some type of preferated bench top with vacuum collection. Pics would be appreciated thanks Scott.

I am looking at an Edelbrock #7115 Tunnel Ram manifold. It comes in oval port and I have Rectangular port heads. For the most part the runners look pretty close to the same except at the ports would I loose anything using if I port match the manifold to the heads?

Thought I'd put up some pics of another Vic Ram2 I got in for porting. This is what we start with. Ugly doesn't begin... Notice the end wall above the runner...I'll fix that later. This is an earlier casting...must be an older intake. It's not near as rough as the newer ones, but still...

Hi guys, i have an Edelbrock Victor Ram that i would like to get ported for my 555 BBC. I bought the manifold some years back and it was more of just a lake motor, now it is pretty much a full tilt race deal so i would like to squeeze everything i can out of it. Just curious who some of you have...

I have been porting my Victor 4500 to match my Blue Thunder B port heads, what a job ! I am looking for a few guide pictures as well as some extra info. I have removed the clover leaf, so now it is a full open plenum. I am going to mill my 1" spacer today to remove its clover leaf design too. I...

O.k so I have a set of heads that will support up to 509 cid. I'm building a 557 bbc. My Q? is to port or not to port?? My local guy says his expert can gain about 15%.(porting my heads) Edit I just read my own post and it sounded stupid even to me. I dunno what am I leaving on the table? I'm...

I got a set of BBC 290's that were originally oval and now are rect port heads......... ( i bought them this way ) Now can i run a oval port intake or does it now have to be rect port ? Or just gasket match the ports on the intake to match..........
