I think this is a good indicator that the end of the Mopar SB and BB are on the last leg. How often do you see a non hemi Mopar winning at the track or street when the HP requirements are over 1200-1500. Thank God we have a strong foothold on the nostalgia classes, Mopar days and stock eliminator.

Has to be a Single cast intake single 4, Cast Iron Block Wedge Engine.
Has anyone built anything close and tested on a realistic Dyno with numbers?
Thanks

Yeah I was very surprised to see GM introduce a 1000 hp crate engine. That is crazy but also kind of cool. If those engines are available and the price is fair then you'll start to see a lot of them show up at the track. Mopar Performance could've introduced a 1000 hp big block crate engine years ago when had the blocks but I don't think there was anyone left at MP in those days who had the guts to make a project like that happen. It could've been done but it would've required breaking some of MP's old rules about which kind of parts to use.

Yeah, and I can see the local relative well to do midlife crisis GM wing nut buying one putting it in their bracket car and going 10.50's

Goodwin Competition made 1200+ HP NATURALLY ASPIRATED w/ an Indy -1 head on a dragweek motor built for nitrous. You believe that?

In reality, I think it would take something like a Predator or a good B1 MC or PSO to do it. Or whatever the biggest Indy conventional heads are now...600-13 or something like that?

I find that 1200 NA from a -1 head hard to believe. Im not saying its not true, but wow thats hard to believe. A -1 head can flow 400cfm, but still hard to believe. Now 1200 with nitrous, yes that i will believe all day long

99 Hemi and be done. Would have to make a "cast" intake but HP goal would be met and exceeded.

Mopar has some nice choices at the 1000hp level, not so much at +1200hp level. That's going to be more of a one off, but it can be done. Me, I like the moved Center Line, 4.84 bore space 655 Millenium Hemi that Best Machine did a couple years ago. Made north of 1350hp...Problem is, no one makes a cast intake for those heads, so that leaves us just one choice...

A predator head engine. Problem is the cubes....I don't think there is a moved center line block & head for those available, but if there is, I would go that route but those heads do use a Hemi block, so maybe Best Machine can do another one of those blocks....no idea.

Lastly, as suggested, the Pro-stock Hemi 99...But again, the cast intake is the issue...Looks like those use a chevy 4.9 or 5.0 bore space block. Makes sense if you think about it. the chevy guys use non-skirted blocks like PS, and whomever builds one of these is likely to use a GM trans....block would typically be all setup that way. There are a couple for sale right now. Check RJ and For A-bodies only.

After all these years, we have trouble getting stock bore space replacement blocks, let alone anything after market to go even further with...Kinda tells you where the Mopar hobby is going...

Yeah, tooling up a cast intake would cost less than trying to make some other combo work. Shouldn't be much more difficult that figuring what really works and then making a pattern. Although I'm not sure how well supported the 99 Hemi is anymore. Might be a struggle to find parts.

Exactly. Some guy all over the Mopar pages on FB has a white Duster he's putting together (writing checks) for drag week, supposedly, and loves posting pics of it. Gets real butthurt when anyone questions it.
Goodwin builds some awesome stuff, but I wonder what they know about making power w/ -1 heads that NOBODY else does.
