Well you can bet I'll be checking mine as soon as I get off work tomarrow.

 

HI!... When you guys get bored of porting your TB's, and TB ELBOW's you can move on to the upper/lower intake manifold! LOL!

So how close did you get it to matching the gasket? +/- .003"

 

HI!... DEAD NUTS ON!!!!!!!!!!!!!

 

Sweet!

I am hoping to have the time to Port and Polish intakes w/ gaskets + Exhaust manifold w/ gaskets on the truck in the next few months.

 

Neal has to much time on his hands:-p why didnt u just have it bead blasted to port the whole runners? not just the ends.

 

HI!... Bead blasting wouldn't remove much material at all really. I looked into getting the intake extrude honed but they wanted like $500(CAN) to do it. Not worth the 10H.P you MIGHT pick up. I noticed a HUGE difference after I did mine. The big trick was to unshroud the fuel injector tip.

 

do u know if they have after market intake manifolds for our trucks?

 

No one is mass producing truck manifolds. There aren't that many companies that are even making intake manifolds for Mustangs.

You might be able to find someone that would custom fab an intake, but that would be an expensive undertaking.

Some time soon, I am going to do some work on a spare PI intake that I have. I thinking along the lines of cutting it up so I can do some porting work and then welding it back together.

 

HI!... I'm in the process right now of hand building a custom sheet aluminum intake manifold from scratch. Runner length has been drastically shortened to give more mid range and insane top end. With my T76-GTS turbo project, low-end WON'T be a problem. The plenum will be on top, instead of below.

 

yeh i'll prolly have mine beat blasted... but its hard to find a non PI intake manifold... for a 4.6

 

alot of the power improvement from the pi heads is in the intake itself.

realize this isnt cheap, but worth considering.

that wont work... i'd loose so much torque not to mention the plastic ones dont last as long and those are forward facing those are side inlet... id have to find one for a truck
