Too bad you could not see the beauty and simplicity and assume power of the blower motor.?
You have most of the parts required already.
Now you are going to buy a head and rework it?
Whats the differnce from porting a 234cfm dart shp head from porting a 920 head
to more than 234cfm

Typical is 240-250 ( non profession home porting 2.02x1.60) on the 920 head.

Yup thats the data I got on those heads 234cfm in 170ex.

I got my friend to port one port on his 920 heads. after showing him a few simple basics and the basic port form he was seeking. ( I showed him one of my finished 305 heads) He had never touched a cylinder head in his life. He spent 1.5 hours on a intake port. remember he has never touched a head before.
After 1 hour of his work I flow tested his 1 intake port with the stock 1.94 valve, stock OEM valve job, just his porting.
IT FLOWED 230 CFM.

if you ordered a rebuild kit from summit why did you not look into these

You seem all over the planet and seem to be being pulled to what ever is stuck under your nose
like a used tunnel ram....

Lol.....not at all actually, I researched, I decided to keep the big van, and then decided what I wanted it to do, and how I wanted it to look, and perform, and I kept coming back to hoodless, and a tunnel ram....and really.....I blame you, every GD time I searched tunnel ram on Google, it kept coming back to you....and your many positive posts on them....
So if you feel like busting my balls I'm blaming you lol....and it wasnt stuck under my nose, i activily went looking for it. As for why I didn't order more today from summit, I had already paid for the intake, and hadnt planned on ordering anything right now, but had sold some g-body parts I had so had a bit of cash on me...when my parts manager ordered his rebuild kit today, I simply had him double it. So back to the begining, 750dp's, or the 600vs.....if you had to choose.....which makes more sense? And how do you think this thing is going to work?
Yes......I'm a pain.....I know this

I do, and would love to try one some day, but I just wasn't feeling it, its not like I'm going to toss these heads, and I'm using the spare motor I had for this tunnel ram build, so I will still port the heads,and still at some point rebuild this motor,and if i want to go blower, I will sell the panel, and buy something else and try a blower motor....all is not lost, I just want no hood, lots of motor, and love a tunnel ram so i figure I will try it.

I think it will be the result of a very convoluted plan.
Here is a good build plan you could have followed to the letter.
Chevrolet Small Block - Engine Buildup - Tunnel Ram, Nitrous - Hot Rod

I think you just called me a horse lol......better then a hippo I guess....

My choice for the tunnel ram motor you are trying to build would be
two edelbrock 750's 1407. with the choke horns cut off.
put on the Summit200/Brodix ik200 heads. with Isky #201534, isky 201547 or isky 201549. 1.5 summit/scorpion roller rockers

and get the right converter and gears for the job.

By next week you will have a whole different plan. I am sure.LOL

Your killing me here, i can't actually find the cam specs on the anvil build, I have tried, and like I said, I haven't bought a cam yet, so I'm open.....fine, i wont have killer Motown heads, or a dart block etc, but really, how convulouted is it.....10.5 compression, 2 dp carbs, big solid lifter cam, good flowing heads, say the brodix IK200's. .....your saying this is a terrible mixed up plan? The plan is -450hp, decent reliability, cool factor, and a big snarly sound.....don't even say "get a thumpr" I don't wanna hear it....and would like to actually hit my HP target.

Kinda committed now....motors at the machine shop, and rebuild kit ordered, and intake on my bench.....no turning back, just fine tuning now...

Yah, I have those already, I forgot, have a set of no name 1.6 rollers, and summit 1.5.....the 1.6 were a freebie, and the summits were $100 and a pro comp intake trade.

The lunati cam in the anvil motor is Lunati #40119
The other parts of the anvil article are found here
Index To The Anvil Series - Engine Buildup - Hot Rod Magazine

The cam is shown in the 3rd article.
The Isky cross reference cam is Isky 201549.

if the dart heads come in with cheap valve springs you had best replace them with the right stuff.
Both these cams are serious cams and need serious springs. DO no use 1.6 rockers.
These are not for the faint at heart.

YOU MUST check VTP clearance with both these cams. You may have to touch up the valve reliefs if the block is 0decked.
you'd best discuss this and the details with your machinst.

I remember reading the anvil article quite a few years ago

I hate tunnel rams.

And if you run dual 750cfm carbs you realize that is 1500cfm?
If they were sitting on top of a supercharger you could get away with it.
