Eric Weingartner flow tests a CNC Stealth head. Pretty interesting. Search ‘Mopar 440 Source head review with real flow numbers’ on YouTube. Sorry guys, I’d link it, but I’m a little too technologically impaired!

A YouTube channel called House Of Mopar has a 383 build and dyno results. Ported 440 Source heads, Bullet cam designed for manifolds. Ran with headers on a manually controlled dyno (Stuska maybe?) made 460 hp. He explains why they ran it with headers and a couple other glitches but it’s an...

Impressive build there. Did you use the MM Source heads? In the article I noticed they milled the stock looking ends off the heads (my favorite part of those heads lol!).

Ok, I thought they might be Rockets, the rim looks like a high polish.

Looks great! Rocket? What sizes?

He might ask the question and answer the question, but every dyno test I’ve ever seen shows headers outperforming HP manifolds from the bottom to the top. Even when headers are the first mod done to a stock engine. I prefer the stock look of manifolds and the Pure Stock cars and all but they’re...

That’s impressive! I know I’m in the minority when I say I wish you could have tested it with the exhaust manifolds too lol. I get it though, head pipes for the dyno and all...

Running my Charger years ago at a Wednesday night bracket race, I get beat first round by a girl in a ‘70 Nova who is a good bracket racer with almost the same dial, high 13’s. When it’s side by side like that it kinda seems like the cars know they’re in a race and they’re trying as hard as you...

Nice! Love the stockers too.

Great job! Love the stock appearing cars like this. I think I see a wrinkle in that redline!

Just an update, I went with the Crower 32243 cam. Talked to Shane at Crower a while back, this cam was his recommendation and said he gives a deal to the forum guys. About $150 cam, $100 for lifters (Summit $180+). Side note; Shane doesn’t work there anymore. In the meantime I painted the engine...

Post 106 does show the Purple Plus lobes. The Crower #32243 is a shelf cam. If their adv. is at .006 and using AJforms formula for Intake Closing Angle, that comes out to 69* ICA. Most of the others we’ve talked about are in the low 60s. Wallace calc. says the overlap is 63*. Too much? Hell I...

Haha. My bad, it doesn’t say .904, I must’ve seen that somewhere else, dammit. Wouldn’t you agree the Howard’s .904s in the high 220s-230s (to work with my 10:1, right?) have more lift than I want with stock rockers and close to stock 516 heads? What do you think about Shane at Crowers rec...

I was looking at Howard’s lobe list on their website and saw a couple lobes in the ‘Aggressive .904’ section I thought would be good for my combo (though these don’t have as much lift and .200 as the Howard’s list Dodge bro’s posted in post #106). I called and left a message with Tim Stoddard...

That’s the .531/.547 - 110/106 right? I believe you and all, but just don’t want that much lift on stock rockers, and I don’t think my pocket ported 516 heads can use it all. Thanks though.

Noted. Thanks.

Thanks. Iron heads and exhaust manifolds.

Well, sorry guys but I goofed on my comp. ratio calc. I’m at 10:1, not 9:7. Don’t know how, I know it ain’t rocket surgery but, CC’d everything again, spot checked, 10:1. California 91 octane premium here, detonation my big concern. ‘69 Barracuda 383 Street/driven to track 727 2500 stall 3.55...

Thanks, I understand that explanation. Wyrmrider, thanks for your help too, I really do appreciate it. I haven’t been able to absorb all this information at the pace this thread was moving, but I did learn a lot. Thanks again everybody.

Aw man, yer killin me! 112 now? I don’t think anybody recommended a 112, unless I just went with a shelf cam. I’m talking about a Lunati 702 on a 110. No good?
