Was wondering why Valako or others haven’t been fabricating them. On a larger scale at least.

Here's some more help though.
Also link from Raylar site. (notice the link address in the address bar once ya open it.) Tunell raaammm!!!!-arizona-speed-marine-496-intake-manifold.jpg


I wonder what the details on the 'Modified plenum chamber shown on manifold base 540-572" are?? I have extensively modified 500 efi manifolds, other than carrying hp on a 540 to 670/680 range flat to about 5600/5800 with a big torque tradeoff (but I never finished true testing of limits with a 9.5 or 10-1 engine). I have seen either a AZSM 500efi style upper with upper dividers removed in one random internet pic (or it was done by lingenfelter or innovation) but never seen anyone mention using one. Is this a pic from old advertising or something recent?

aside from the 500 lower I personally modified, first time Ive ever seen one like this, found it searching those images that were uploaded, I see it was something flagship offered from AZSM in 2009, havent ever seen it anywhere else and I dont think it caught on or maybe didnt work great. My testing with similar gave mediocre results, big tq loss but did carry rpms, hp higher, Smitty

supposedly asm did the r&d and owned the manifolds and mercury paid a fee to them for use of it...

I see Engine Masters mentioned on this thread and I’m a huge fan.

The guy that runs the dyno (sorry, don’t remember his name) often mentions motors he’s built for race boats, and I think specifically offshore.

Anyone know of him?

Seems like a very sharp dude.

He often catches what the other guys miss or are stumped by.
(Dulsich is also very sharp)
