Hooker makes long-tubes for our trucks. Check out pacificp, a few guys have em. The only options are carbed intakes (either using a carb or converting to efi and lots of wiring) or marine manifold (everything pretty much bolts up but lots of wiring still and fuel lines)

I am running the $180 painted $350 ceramic coated and $540 stainles steel
1 5/8" primary non-equal length 2 1/2" collectors pn 2462 HKR.

With a mild Fastchips PCM tune and teh headers I dropped 3/4's of a second in the 1/4 mile.

ghere is some furthur info on installing ANY header into a 1996-2002 Vortec 350/305 vehicle.

you da man

 

I stoped at headers and intake with my 96, I would go after the marine intake(came about after I sold the truck).

 

What about the RamJet manifold? I would assume that its a similar process to get that working instead of the marine manifold. I would also think that its worth a few ponies over the marine as well. The only difference would be setting up an intake to work with the manifold, because obv. the throttle body is in a different location.

Hog, what do you think of the RamJet in comparison to the Marine? I am planning the RamJet swap for this may.

The Ramjet is probably worth a few hp as it is more of a tunnel ram intake while the Marine intake is a cross Ram setup.

The Ramjet forces sthe intake air to tun 90° the Marine intajke doesnt due to its TB position.

I would love to see a dyno sheet comparing the 2.

The Ramjet install would be a tad more involved, but could be done nonethe less.

Hopefully I will be able to let you know about it. I am seriosuly planning it for the spring, but I would like to be doing a cam swap too, so it wont be a complete comparison. Maybe if we could compare them with the same cam... Hog you wanna do a cam swap???

my buddy had a 98 silverado with the vortech 350 and it had hooker long tube headers k&n cold air intake crane cam 210/224 @.50 powermax truck cam, crane powermax tuner, 3:73 gears, shift kit, and a throttle body spacer and he ran consistent 8.60's in 1/8mile hope that helps some!
