How are the imco power flow manifolds , better than gill,


thanks guys

Uncle Dave

Imco Powerflows are good (I have a set of these on my 500HP small block tunnel hull havent touched em in 7 years- runs great.)
Imco Powerflow pluses are great
Stainless marines are in between the two

They are manifold systems though..- but very good ones.

Between these three Id take the "deal" I could get especially If Im not going over 600 ponies

Lightning makes great headers if you can swing the dough Id go with headers.

Oh sorry I didnt answer the question...... YES.

Both Teague and Boostpower use the Imcos.
(good enough for these guys.... Id wager its good enough for you)

I dont know a single performance builder using Gils on either Coast (doesnt mean they aren't- I just haven't seen anyone "lead" with Gil)

lol.... nah. Actually they are what I am wanting to buy. I have Gil dry's now, but think the lightnings will make a little more power and make getting to the plugs easier in mine.... oh and the cool factor too!!! haha

He wants something that is going to dump water farther back than his Gils. Rev marine's are not going to do that.


Pretty much the same. The Imco's also use wet joint between the riser and manifold.

I'm about 99% sure that your Gils will be just fine for your build. The only thing that is going to make more HP and dump water farther back, with a reasonable price, is CMI's.

If you buy Revolution Marine you can get the long stainless steel risers plus now when you buy Revolution Marine exhaust you get EDDIE Marine manifolds and risers right from eddie marine. that's the best deal

Dana has a dry joint between the manifold & the riser.
