Covid-572: Pandhemi

Good morning Ladies and Germs.....

Today, for your viewing pleasure.....

I give you the Covid-572: Pandhemi.

Born on 4-26-20

(Painted and all that sometime afterward whenever it was I got around to it)

Not really. I'm not too into the process of "naming everything" like that but maybe this name will stick?
Ah, who knows.

Been a fun project.

Ohhh, that's nice!

Thank you Mark!

Have I mentioned it is stock appearing ?

(.....in this one spot, where the white plastic things go)

If I’m getting too technical let me know 😂

Congratulations to the proud father!

and I like the name, that's clever.

That’s got 500hp written all over it!!!

I put the high lift purple shaft in it, man! Gotta be good for at least 5 and a quarter

Medium Daddy says thank you very much

Thank you... I probably binge watched one too many Motor Trend on Demand shows during this
whole deal, which led to the whole naming thing.

He either has a twin or someone stole your idea in the other 572 post. LOL. It's an identical twin.

I probably overdid it with the posts here but will stop soon.

It's so slow around this place, it's kinda sad.... but it's like that all over except social media.

I think we need to put the pedal to the metal to remember how great that feels. 6 months and counting for me since the Halloween Classic at Norwalk.

Looks good. Do the pulleys all line up at this point or do you need to move the alternator out to line up with the water pump? Looks like you have the correct throttle bracket and return setup, you'll need a long throttle cable to reach up to that intake! The coil mount location looks good. What else do you need to sort out before it is ready to go into the car? Is the fuel system ready for that engine? Where will the adjuster strap for the alternator go? Over to the engine or run it the other way to the frame?

Looks good Zippy! I finally own my first Hemi too, they are not real fun to work on but definitely fun to drive.

Looks awesome Zippy! Is it going on the dyno?

Well, yeah that would help!
I'm sure not any sort of hardcore racer but I do enjoy testing and going at it once in awhile.

A year ago for me May 5th. What would really do me a whole lot of good is to do an entire day of nothing but 60 foot, adjust shocks and try to learn something about suspension, as I feel I know next to nothing at the moment.

Can't do that, so time to start changing things and make sure I confuse myself as much as possible....

Nice Rich! Really looks great!

Hey thanks. Adjuster strap will go down to the K member (Weld a small 3/8 ID tube, run a bolt through it and attach the strap). The alternator fits well but the bracket should be 1.040" thicker for it to line up, so I made a spacer to use in that location + drilled the tapped hole on the bracket out for 3/8" through bolt so I could use both "ears" on the alternator. I got the pulleys to line up within 1/32" using the motor plate as a datum line, after a little lathe work. Hopefully the motor plate isn't too difficult to live with for limited street use...I will find out.

I do need to repair or replace that Demon carb shown in the pic, as somehow I managed to warp the secondary metering block a couple years ago. Will probably buy a pair of replacements from BLP. Picked up a QFT 950 and have been using that for awhile....but it is too small for even the 451 per track testing, so I don't want to use it on the 572 unless I swap the main body for something larger (I actually have one on the shelf I forgot I had, and might go down that road).

I have a pretty overkill fuel system, 250gph pump, it's older, need to test it and make it all fit the car a little better than it does currently. The car itself needs more prep than anything else at this point. I do want to replace and repair some sheetmetal and have started doing some of that while waiting for engine parts.

This is a baby step forward towards the RBRE/MP single plane and/or the tunnel ram later on.
I know I need to experiment a little or I'll get bored.

Congrats to you too PS! Thanks!

Thanks

I was quoted 800 bucks a day for engine dyno awhile back, which pretty much told me I was probably going to head right back to JAKE68's Dynojet soon as I can swing it.

I need to put that into the rest of the car more right now.

Using both ears on the alternator is a very good idea if you can. Are sure that alternator is going to fit in between the K frame and the motor plate? It looks like it might be too big to fit. If you are going to be testing different intake manifolds and carb combinations then you might as well make your fuel supply setup in the engine compartment really flexible. Same with the wiring and stuff like that. That is another reason why I wouldn't worry too much about cosmetic details since if you are going to be swapping parts around a lot of little nicks and dings happen. Not to mentions drilling some holes here or there.

I have no idea where you'll end up for a carb and manifold combo that work on that engine. 572 inches is a little past my experience. The numbers say you'll need a Dominator for WOT but I'm not so sure I'd want to live with a Dominator on a street car. If it was me I'd sell all the carbs and switch to EFI now but I don't think that is where you're at yet. A dual Sniper setup on a Stage V intake would probably be just about ideal for street driving and WOT use.

You have had carownersvirus for over 30 years! HEMI-ITIS too!!

I know for sure it's a little further from the K frame than the oil filter is, on the opposite side. From studying other vehicles I know it's a little further from the K frame than the Mike Doty bracket with a much larger GM alternator on an E body. Tape measure looks good, using the B engine in the car as datum. I'll find out during mockup if I got it wrong and make whatever adjustments are needed, in case I overlooked something.

That's the idea. Flexible and easy as possible. It's been that way since the '90s, I just intend to move things around, integrate it all better and make it look like it belongs, and make it easier to work on at the same time.

I get that, but it's not really the details I'm chasing, it's more the big picture. You haven't seen the hole in the top of the RF fender that I can almost put my fist through, or seen the old repair from the '70s to the cowl that has now failed and cracked, and stuff like that. You'd understand if you got a close look. It's quite a long way from patina and needs attention.

Right, EFI is cool and all, but not for me right now, maybe later.

I can probably drop most concerns of having too large a carburetor, now the issue will be 'what is enough'?

I have one 1.450 venturi/1 and 3/4 baseplate "950".
I could potentially get another matching one and put those on the tunnel ram.

The Edelbrock single plane 2x4 looks to be worthy. Chuck told me that intake and two
750 Edelbrocks runs really good on a street 572 so I have been looking at those ever since. That's probably the best one for hood clearance/stock height. Might try that later.

True words, Al.
My condition is normally aspirated, though.
I'll never be as serious as many of the total animals (in the most respectful sense!) on this site are.

If it weren't for the time given by Covid..........
(2 hours commute I don't have to do: Very good. All the band's gigs cancelled: Very Bad. But....time is time)
No way would it be done, already fired on the ground and so on.
I'd probably be wondering when I'd get a chance to work on it.

I hope to attend Carlisle or another event out east again someday, shake hands and talk again.

thanks Ted.

Looks good......I like it a lot...Have a similar engine myself......The 572 is a great size for all around fun and reliability...

Couple of things I have learned, you didn't mention if yours is an iron block or not...Assuming it is, if you have trouble cooling, switch to a FlowKooler water pump. those things are awesome.

Carb looks a tad small.....Hemi has a big chamber and can be a cold blooded B$tch to get up to temp....Recommend calling Thumper when you decide to upgrade..

Yes the Edelbrock dual setup with a couple of Edelbrock carbs would be fairly inexpensive (by Hemi standards) and should work really well. If it was me I'd use the Edelbrock carbs that are jetted for duals. I think they make them in 500 and 600. I have a set of the dual 500 Edelbrocks for the dyno room that we've used on a ton of engines over the years. Those carbs always work great regardless of what they go on. Blower motors, tunnel rams, cross rams, etc. A pair of them will easily handle 700+ hp and they don't cost much to buy.

Now you've done it!

You have me contemplating the Hemi lifestyle!

Rich you need some quick disconnects on your fuel lines like my friends mild vette. Lol Mike

Not to be a PITA, but dual 500-600 eddy carbs on a 572 will make things worse. Right from edlebrock the 500cfm rated carb flows a little over 350cfm....

We run dual eddy 800 Thunder series....They were very close OOTB on a 572 Hemi....

Mark I came up with a couple little ideas (nothing earth shattering) to help spread the cost out which made a noticeable difference. If you need a push, sometimes stuff like that can help. Feel free to PM, or FB Messenger, or call. But if you call pls use the actual phone...not that goofy messenger thing.

Randy and Andy, thanks to you both for the input even though it may not agree 100%. Opinions are welcome.

Randy I know you've played with them for years and have done some street driving, so I def. see the value in what you have to say. I think I would want at least 750s as an end setup.

I do have three or four Edelbrock 600s kicking around here, and that could potentially be the baby/starter kit setup for the Tunnel Ram. Two of them are already rebuilt and tested to be working well on an old big block. So I could slap those on just to start somewhere.

burning question:
I already have one newer "950" carb on hand (1.450/1.75, probably doesn't even flow 900).
I could buy a second matching carb.
Could be an eventual big dog (for me anyway) setup for the Weiand.
Are two of those "950"'s on the Weiand tunnel ram too much?
It doesn't seem so, but I have no clue.

HEMI.... for lazy mans choice for spark plug swaps! Great looking mill Zip! I’m afraid I’ll go to the grave not have owned that awesome wideness!

It's looking good Rich !
I like the picture with the GTX in the background best.
I have run my 572 with the same intake you have and a Race Demon RS 950 anular converted to 1050 down leg booster. I have about 15 passes on the car. All but one pass on the strip was done with that manifold and carb. I switched to 426-3 and a Gen III Ultra Dominator and I don't have a good pass on that set up to date. I tried an OTB baseline pass and it was way too rich . I do have some street miles with the Dominator and I like it now after I did some mods to it. I still need to change the linkage to slow the secondaries opening. Things get real exciting when you try to ease into the throttle passed a certain point.
I am really happy with my 572" and I bet you will be too !

Mark

Thanks for the support!

Need to get started on a list of next steps for the GTX.

Looks good...

Thx Al.

Your standards have historically been pretty high, so thanks for the acknowledgement.

I'm trying to move up a level or three in that department.
