The number of errors multiplies, when improving the prototype :lol: gorilla tape fixes small proplems..

13 min 40 sec.

4 barrel to 2 barrel, about 100cfm less through the motor, about 100hp less.

The 318 Mopar project picked up 20 cfm with a 4bbl intake, more than 11 %.

In the TMC program video comments it's been pointed out the cam grind is a tight LSA 327 350HP cam.

That'll make 1 for 1 with a 4 barrel, but I think it'll need to be bigger for that baby 2 barrel, a 500 cheater carb might do it.

David uses a fudge factor for the restrictive air intake, so the TMC program doesn't have restricted intake racing classes programming.

Cam grind at 15 minutes.

Oh wow people, this is fun bashing!

As many of you guessed, I have issues with a lot of youtube videos and other such stuff.

Here is one case in point.
I bought some binoculars at a pawn shop for a good price I thought.
Yes, I had to have them cut the price in half because i showed them
one of the lenses had a chip, I explained, and it is on the inside as the binoculars
had to have been dropped to cause that.

They were made in Japan, Japan optics aren't bad, they aren't Zeiss.
Lenses made famous by Nikkor, and Fujinon, along with high end
TV production gear too.

So I go to youtube to find tuutorial how to clean in inner workings
of the binoculars and get them up to snuff if possible.

THEN

Half way through the video the guy says, "just blow on it gently
and with a little saliva, you wipe it clean, then put it back together."

WHAT

I dated a gal who was some kind of optical specialist in the US Navy,
also did the parascopes in subs and other fun stuff. i remember her
reading me the riot act when I cleaned my sunglasses by blowing on them.
She informed me so matter of factly saying, "that is one thing you never ever do
to any lens, BECAUSE those little microbes from the mouth that comes into
contact with the special optical coatings, will eat away at them and ruin them.
Never ever blow or spit on any lens attempting to clean them."

And so with my nytril gloves, lintless cloth, 100% USP Isopropyl and sit down
to dissasemble, clean, reassemble my cheapo binoculars. I pat my self on the back
for listening to her and ignoring youtuber.

Oh, and I have one hell of a nice pair of binoculars too. Someone put a greasy
thumbprint on the inner glass (forget the exact term for those glass triangles in there).
Yes, there was a small chip on the edge (not in the field of view) that had worked
it's way into the field of view (which I removed) and now can't tell anything was
ever wrong with it.

TWs Dyno, eh? some of DVs stuff also?

I'll just leave you with these thoughts, you folks are sooo ba'ad....

Me thinks you get great joy pulling back that curtain in the land of oz!

I know I do.

Cheers

Anyone watched the different 318? I dont know about mopar, but i love it when one pisses people off by mentioning that ported heads add low/midrange torque..

Actually this manifold deal is one place where the flow bench is a big help.

I find shallow and small plenum intakes like that fed by too small of a carb ( too high air speed ) thrive on a funnel shaped ( minimum) 1” inch and preferably taller spacer to slow down the velocity allow more of the air mass to turn into each runner, especially if that center divider is allowed to be removed.

Stan can you explain to Charles why he's using the calculator incorrectly half way though this video for a carb flow restricted 8 cylinder, it'd be correct use if he had a 4 barrel.
He's not going to get 1 for 1 at 170 odd through that carb on a 320 ci with a 223 cam, needs at least a good 500.

But I'd be guessing. Whilst I'm guessing, :D I'd also go for a wider LSA. :wink:

107 to 108 LSA 276 276 @ 006, 223 223 @ 50, 471 valve lift. Installed around 103.5.

Most people don't realize that a "Stocker" 318 2V has to have valve lifts of only .393" intake and .421" exhaust to be NHRA legal.

That is mainly why they needed larger duration lobes..

I can tell you this although I realize this isn't a 350 Chevy, but a 2bbl 350 Camaro stocker has run 10.90s according to the owner, I've seen low 11s in legal NHRA stock trim, which show observed HP to be over 360 HP, these engines have about 220 CFM @ .400 lift @ 28 inches @ the intake port, although a larger Rochester 2bbl is used.
Racing a NA NHRA stocker should be mandatory before any posting.

I wonder how much duration at 50 ?

Charles will have up around there in port flow I think.

How is this abortion not completed?

So over 50 years David Vizard has been in the industry a 1hp/ci dingleball honed 318 is the highlight!

I see nothing of value here, just worthless youtube content.

All I see with this project, is an immense waste of time using a flowbench and no forward progress.

Just stick a 218@.050 cam in it already and bring it to the dyno.

I am just going to make a wild guess here and figure you have absolutely no interest in testng NHRA "stocker" required pieces for doing well in that venue ... LOL.

Really, only people using that NHRA combination would have very much interest at all.
