Bit the bullet and bought a ported intake adapter and a ported Weiand tunnel ram from Mr. Craine.  Both brand new parts, but have been around a bit.  I think the adapter is serial number 006. 

Gonna use the TR with my vacuum secondary 600's to see what it does. 

Will be an interesting venture and even if it doesn't do stellar, it will make it much easier for me to change cams down the road.

The tunnel ram test should be very interesting.
Have you experimented with camshaft timing? - adjusting ICL?
I recall this cam was installed @ 105 ICL.
With the very good flowing heads (for 352 cu. inch) and reasonably large CSA (again for 352) perhaps retarding the
ICL to perhaps 108 ICL would be beneficial?
I do not recall if you had one of Jays adjustable cam gears or not.
It would certainly be interesting to test various ICL's while you are on the pump testing.

Good luck!!

What do you all think?  Had to do a significant amount of pushrod tube grinding and in the end moved the rockers over a hair, but finally got it all on yesterday.  Went with Tommy's suggestion and just threw the 1850's back on.

Who knows what it will do, but it will look mean doing it!

A careful study of failure will yield the ingredients for success.

R&R connecting rods came through with aluminum rods for me.   I'm going to dyno  the 352 with the tunnel ram, swap cams and dyno again, then I'm gonna go inside. 

These rods only weigh 572g.  FE rod journal diameter, SBC wrist pin diameter, and I sent them some rod bearings for them to drill for the dowel holes.

If you can borrow a pair of 4224 Holleys(660s), you may find an additional 12-15 hp over the 1850s.  I have not had as good luck with the 1850s on my Tunnel Ram, or Tunnel Wedge as I did with 750s or 660s when racing.  Just something about how the metering works enough different to make a difference.  That engine looks much bigger than the cubes would indicate.  LOL.   Hope it helps.  Joe-JDC

The rods look real nice Brent, and they got them done quick, sure are lightweight, wow. For some reason I always thought R&R was in Michigan, looks like Florida?

Yes sir, they are in Florida.  They were pretty quick about it, about 3 weeks I think, by the time I got them a factory rod to sample.

I like how the big end is pretty small in comparison to other FE aluminum rods I've seen.  They used 3/8" ARP 2000 bolts which helped on the big end size.  I did give them a 600 hp number though, because there's no way I'll ever be anywhere near that with the 352. 

I did ask them about street use because Bill Miller said that they have customers that daily drive with aluminum rods.  They told me it would be no problem, just use some common sense about operating temperatures, setting up bearing clearances, etc. 

They also drilled some bearings for me.  I was planning to come up with a fixture to drill them since no one offers shelf FE rod bearings that are dowel drilled, so I mentioned that.  He said, just send me some bearings and I'll knock them out for you.

It was a good experience overall.
