Jays Adapter, CHI-3V manifold raised runner FE idea?
« on: March 03, 2017, 10:27:58 PM »
I got to thinking last night and that's always a bad idea.....

I was wondering if anyone had tried to use a manifold designed for the CHI "3V" heads on one of jays adapters.

http://www.chiheads.com.au/shop/manifolds/3v-ford-cleveland-manifold/#

I started looking at them, and it looks like the CHI port is raised up quite a bit compared to a standard 351C intake



So I'm wondering if this would make it possible to do some custom porting on one of jays adapters, and raise the port in a standard run of the mill edelbrock, FElony, BBM or even a stock head.

Obviously some floor filling would be needed, but if the CHI 3V port isn't too high, it could possibly allow for a raised oval port FE head.

Just looking at picks on the internet makes it hard to judge, but it looks like it might work.

Years and years ago i cut up a stock 390 head to see how far i could raise the roof, then proceeded to clamp another 390 head in the bridgeport, and using a 1/2 inch ball mill i raised the roof about .250-.300 ( memory fails me here ), then i filled the floor with about 1/2 inch of JB weld (at the port) I ended up with a more oval port that was smaller in cross section than the stock port. Then i flowed it on the bench and was very impresses with the gains. Life happened and i was never able to get any further than that, but i've always wanted to take it up again.

with modern castings and jays adapter its more feasible now than ever. Of course it's going to have to work pretty darn well to justify going through all that work considering how good heads like Blairs ProPorts are with a stock intake location.

thoughts?

I have a special version of the intake adapter for the CHI 3V manifold.  Unfortunately, a whole bunch of port matching is required, because I have not written a port program for that version.  However, one guy on the forum here has done this, and it came out very well.  See the info starting on page 4 of this thread:

Wow, what a beautiful car. A+ on craftsmanship.

So comparing the picks of the manifold adapter you made for him against the standard 13001, it does look like the ports at the manifold are a bit higher, I saw he filled the floor a bit on the adapter.

Look like a great manifold combo all around,would be fun to play with but the cost for is up there a ways...

If I could just win the lottery ....

An Edelbrock 2863 intake fits very well on a FE Power adapter, pretty much the same idea as you're thinking about with the CHI intake.
