Just cut the deviders back and give a nice rolled end as mentioned.With the dividers In place as cast will cause the wet fuel from the carb to be directed to the four corner cylinders.Let the fuel drop and and the air entrain with the fuel filling the plemum with atomized mixture.Leave ruff sanded surfaces at the runners and floor to help this occurr.
There are a few customers that have our modified manifolds,maybe one will post a picture.

Are you running EFI?

FastmOp not at this time i was planning to use a megasquirt 2 i built a couple years ago thats setting on self but realized it wouldn't work for my needs, also i have everything for a high hp e85 blow thru carb minus a main body so thats the direction im taking this year. Plans in the near future are to atleast back halve the car but id like to full tube chassis the car,and switch to efi then. Im probably going to set the motor up with provisions to add efi in the future by adding,maf,gm style sensors for temp,oil pressure,air inlet temp,crank tigger.
I know blow thru is a pita but honestly there not that hard to tune if you stay under 15 pounds of boost. Over 15 your going to need a "crutch setup" which ive dealt with, and still have the provisions hooked up in the car from when i had the slant installed in the valiant and i was running 20 pounds of boost.

Greg are you running a stock K frame? If so which pan are you running? Not a whole lot of room in there.
Would something like a oil accumulator (sorry not sure if thats spelled correctly) added in the system help? I was think of something in series with the oil pickup line or will that cause pressure drop or inconsistents in flow and pressure.
Thanks all for the help

This is what the plenum of my 4500 Indy intake looks like.

I use a .039 oil restrictor on both my Indy SR and 440-1 with the older full roller needle bearing Harland Sharp roller rocker arms with a solid roller cam I used the same size restrictors on my newest motor with the Eddy M.W. Victor heads with the Harland Sharps on it also

Ill look into finding a different pan thanks for the warning, i really wasnt sure what would fit in my little valiant theres not alot of documentation out there on the web about putting a big block in a 62 valiant.

I have a tube chassis, so can't offer help on what will fit your car. A lot is going to depend on how much rpm you are going to turn, weight of the oil, and G forces. Maybe starting another thread on oil pans for your project is the way to go.

I have a nice E85 4500 custom carb set up for blowthrough that I won't be using. Shoot me a PM for details if you are interested.

With a good pan I've run as low a 6 qt's with no problem on accel. Hard finish line braking requires at least 7 qts .

Well ive put in about 3 more hours gasket matching the intake runners im going to need a handful of new sanding cartridges of 80 grit before i can continue plus im off of work the next couple days so i wont get back to it till thrusday or friday. Yah im doing it on the clock......

Cab thanks for the advice im going to check the size of the restricts that are installed in the head and make sure there atleast .039 and not just a normal AN fitting.

Greg thanks i thought your car was tube chassis but figured it wouldnt hurt to ask. There another thread started about big block A Body pans thats been helpful in helping me locate a affordable 8qt pan that should drop right in, or i could extend my 7qt another inch to get atleast 8qt.
You mentioned rpm plans are to short shift this thing at about 6500rpm but ill have to see what the combo likes. I have no plans to stress the block from over reving it as there should be more then enuff power and torque to achieve my goals. If not ill turn the BOOST UP

Thanks for the pics that helps me out considerably i havent touched the plenum aera yet im still trying to figure out how to cut the dividers down but will give it more thought in the next couple days.

Airwoofer ill pm you later today about that carb as stated in a pervious post i have some new parts to build a nice 4150 carb.

Dvw thanks Doug for the advice and looking forward to meeting you in person

Well im off work tuesday and wensday and plan on working on my junk the next two days probably going to try and finish the mini tub,and I may install a couple more bars to my cage ill need to finish it up before the car is ready. Also i need to start test fitting the powerglide. Ill keep you guys and gals posted,and im sure ill have some more questions
Thanks again all

If you choose to try the seven quart pan,(or any system for that matter) a 30 psi or higher pressure switch to the oil system and a light you can't ignore might be worth the trouble. During a run it is not easy to see everything, and a 30 psi or higher switch will let you know if there are issues with your setup. Put it next to the oil pressure gauge.

Thanks greg thats sound advice i just ordered one off ebay
Check out this item I found on eBay: http://pages.ebay.com/motors/link/?nav=item.view&id=311567553384&alt=web

Check the pushrod to block clearance on a low deck with 440-1 rocker offset. I forget if this is mostly a problem with offset lifters or if it is close with regular lifters too.

I will see if I can find an old post with pics.

Thanks for the heads up 440Jim im going to grind mine down before final machine work is done.

What you guys running for solid roller cam bearings i hear alot of guy running king brand but i have no exp with them? Any and all help is always appreciated
Aaron

I also have a 470 but i'm thinking of swapping my -1 heads for BS heads, would i just blank the oil feeds off and go back to conventional oiling ?
Sorry to hijack your thread.
