Slant 6 intake manifold 'finished'

[benno440]

As per a previous post, here is my handmade slant 6 aluminum intake manifold.
using a mustang 5.0 TB and ford falcon turbo 6 injectors.

Nice!!! I ran a modified super 6.... makes a nice 1/8 miler...

How modified??

 

[sleepar]

Just over 12.1 compression... had just under 400hp... no pix sorry...

Paw, jc Whitney and a few others and a 10# nitrous bottle... the crank and rods was custom made in long beach... in the 'swinging dart'..which started out as a '74 with manual everything and a 3 on the tree. It died in NY on the way from Albany to buffalo

That's some nice work Benno!

very nice work

 

[benno440]

thanks

Nice!!

That's a work of ART! I have a few friends that have a turbo on their slanty that would kill to have that!!!:naka:

Cool stuff for sure!! Had a few cars with /6's but nothing highly modified. 67 Dart with mods like a straight pipe, open air cleaner, good tuneup, aluminum flex fan, 3 on the tree and 3.91 gears ran low 17's high 16's. My 66 Belvedere came as a /6 auto and ran 23 seconds lol. With the same type of mods along with some suspension upgrades (the stock leafs were very tired) it ran a best of 18.10 with 4.10 gears. Keep us updated on the build!!

Very nice work benno440....
Nice TIG welding!

Nice FAB work.
Very impressive.

How many hours did it take you to build this intake?

 

[sleepar]

They wake up... the problem is like the poly A motor... very few hot rodded it.... the 292 Chevy and 300 Ford sixes were and that makes it even more special of a build...

I have wondered why they didn't make a v12 based on this motor for the viper and use the v10 truck motor.

 

[benno440]

took roughly 40 hours to make, including designing on cad etc.
sold it for $750.00
not including injectors and throttle body

benno440,
In my opinion, that is a "great price"
Yeah, that is a piece of jewlery!

Again, great job!

 

[roadrunnerh]

good luck

Im over on FABO and did up this intake for a turbo build Im doing. I have the injectors in the head itself so there are no bungs on the runners. That AL piece is very nice, how I was going to fashion mine too, but that would have hit the turbo in my case.

I fashioned this out of EMT, a piece of plate metal and an old Edelbrock cast valve cover. I bought the flanges off Ebay. I made the runners as long as the original Ramchargers formula for intake valve timing off a stock camshaft, I think it was around 240 degrees. I picked the 4th or 5th wave to keep it under 10 inches. TB Ram tube length doesnt factor in much according to some design sites and I put it here to keep the package as narrow as possible as its in a narrow A and the M/C is over there. With no EFI bungs at a 45, you can make it pretty narrow. I may have to remote mount that IAC onto the plenum for hood clearance.

It has an integral exhaust manifold heat stove plate which makes a nice pad to mount the manifold to. This is turbocharged so there is plenty of heat to prevent icing, and the injectors are downstream so its completely dry. You can make some tricky bends with a dry intake, just look at some stock plastic intakes on the 3.8 motors. I used a good rubber valve cover gasket and sealer for the plenum. I used a Ford Windstar 3.8 TB as it has a PW idle air control motor as opposed to a stepper motor that my MS2 could not handle. Im also using a Ford EDIS-6 ignition with a 36-1 degree wheel off the crankshaft damper. I milled the teeth into the stock slant dampers outer ring and will make a 3 prong yoke to keep the ring from slipping by bolting it to the rigid inner hub and extending the 3 fingers out to 3 dimples Ill drill into the outer ring. That should keep things in line. I tried to make some teeth into a more rigid mount power steering pulley but botched it badly so I went with plan B. Usually turbos dont mind shorter runners but when I first started this project, it was without the turbo. The 3 BAR MAPP is in the MS2 controller so a few nipples off the plenum will work with that.
