Ok I finally got my hands on the Mopar 337 intake for my Indy Headed 512. My heads are Indy EZ-1's with Max Wedge ports and ported and prepped by the great Nick Wilson. Currently I have a standard Indy 2d intake. Does anyone have any suggestions on porting the 337 to the full Max Wedge port and who to send it to?
Thanks, Darren

Larry Smith did the 337 porting for Streetwize that he's posted numerous times on here. His work looks 2nd to none.

I assume he chose the 337 intake as ti will fit under the stock hood.

Yes the intake is going on my 69 Charger so that's why I chose the 337. Eventually going multiport FI but want to try it with my 1000 cfm AED carb first. Yes I have read in detail regarding Streetwizes mods.
Thanks! Darren

Larry Smith did the porting on mine also. Beautiful work. I also use a 337 manifold and an AED 1000 carb. It's an awesome combo and fits under the hood. All of mine making in excess of 700 horsepower.....

Thanks Old School. Does anyone have contact info for Larry Smith? Talk to Todd Marsh aka sasquatch aka Marsh Performance (mopartsracing.com). I know they do a lot of work together.

Be very careful of "beautiful work", it tells you nothing about the execution, only how much grunt work went to the sanding mop. As Jerry Branch used to say "shiny is what sells the customers but does nothing for the engine".

Thanks Andy. Looking forward to seeing how much of an improvement will be realized going from an untouched Indy 2D to a ported 337 that will take advantage of the Max Wedge ports.

Larry Smith is an engine genius, and he is a very humble and personable genius at that. There is nonone who knows anything either about him or his reputation and credentials that would ever dispute that.
'Nuff Said
Larry shares Shop space with Hollis Page HP Engines (another awesome Engine builder and close friend) who is a long-time supporter of Moparts and runs a banner Ad in the Sponsors Index. Tell them Bobby/Wize said Hi!

Nothing against Larry. Vizard says good things about Wilson. At this point of the science, the surface texture for an intake port is still an open question. It appears that under certain conditions benefit may be derived from stippled (golf ball), rough (60 grit), and even scribed (parallel lines at an angle to the port CL) contour, but direct comparisons are expensive and difficult to quantify. They are also extremely labor intensive to apply.
