Seems most of the heavy hitters are running a BBC 540 & twins...From there, a ton of turbo LS swapped cars....
Not seeing a lot of Hemi anything in the field of competitors. We have had a couple of Todd Goodwin powered cars, like stupid fast and $$$$ and one or two G3 Hemi cars, and a few wedge powered ones, but the trend that sticks out for me were all the BBC's with twins...
How come we don't see hardly any BBM's with twins or G3 combo's? I think the one Aussie guy was running one, but his is the only one I can think of. Then there is the W8/9 powered Duster with twins, but little else...What gives guys?
"junk yard" 5.7 hemis have proven to make silly power but people still overlook them.
Wondering why is this parts availably? or what i don't know much about the newer hemi,but i imagine with the right parts they can run just as fast as the LS.

The LS platform is cheap, plentiful, and has a huge knowledge database. The cost of entry to the Gen III is higher and there is far less knowledge out there. You can go to the Sloppy Mechanic's and find all kinds of formula's to make whatever power you want with a 300000 mile LS engine, you can even download the tune ups into your Holley EFI.
I think a Gen III junkyard engine can make big power, but it is my belief that they are much more fragile due to the ring placement. I have a stock 6.4 hemi apart in my garage and that top ring is about as high up as you can get it. I think that is good for power overall but it is not good for someone who wants to huff 15psi of boost in it hoping that the 200000 miles opened the ring gaps up enough.
With a BBC with turbos you can probably runs 8s on accident. If I see a big block chevy with a power adder running 10s I assume it has something wrong with it lol.
You can't read about block limitations of a BBM and then feel good about going out and putting a couple of turbos on it. A 440CID motor with a turbo could easily make 1000HP, how long does that last?
Small block Mopar? Crazy expensive to build to high a high level, and you still have to source a block that hasn't been made in 20 years or more.
The Coyote platform is also a player, but I think the cost if entry is pretty high. You can't go rip a 250K mile coyote from an F150 for $500 to go racing with it. But they are more durable than anything it seems like, Snot Rocket was using a stock crankshaft up until recently. They had to replace them after several runs because it would start to eat the bearings.
Obviously Turbo's are the power adder of choice. The core engine can be so tame yet still make insane power. I can't tell you how many times I times my Dad and I have been buzzing down the highway on drag week at 3500RPM when some 7 second turbo car cruises right on past us at 80mph turning 2500RPM because the car has to have a 3.08 gear to go 190mph. Then he is the same guy sleeping at the hotel when I go out at 6am to check the valves.
If my whole operation burned down and all I had to build a car was the check I got from Hagerty I would probably build a Gen III hemi Fox Mustang. I love the fox bodies but am still a Mopar guy at heart lol.

Parts? Just gap the rings and send it!
Interesting not bad for a basically stock engine i would have like to see it did with e-85 without the water to air intercooler and compare it to say a 5.3 LS sense that seems to be a go to engine for the LS guys.
If i built a drag and drive engine, it would be BBM (forget stock block so there goes that argument) Twins and e85 or dual fuel system. A BBM is a great platform, it has 5 head bolts per cylinder and did you ever notice an LS looks like a baby BBM when you take the heads off?? Lower end is very reliable , and even budget heads have shaft rockers... But again , building a BBM might require a little more research and getting the right engine builder or assembler. BB chevy and LS info is plentiful. But hey they are all just air pumps so not really that hard. Face it Mopars are considered cool by almost all racers, but not that popular that they all want to build one LOL
I think all the same reasons theres not more Gen 2 Hemis or B1 combos in general. $6000 blocks, and one extra part you need to bolt a TH400 to it.
As far as the G3 goes its already been touched on but not as much knowledge, and putting the “Hemi” name on it prevented super cheap ones sitting in junk yards.
And most importantly, and I think relevant with Chrysler axing the LX platform and going back to its K Car and 90s junk roots, there really aren’t many platforms to build a Mopar that aren’t desirable musclecar stuff, and have you looked at the price of junk run of the mill musclecar era stuff lately? Maybe you can find a Dakota or a Cordoba for a reasonable price, but its not everywhere like G bodies, F bodies ,and S10 / Sonomas.
If you want to build a G3 car the most convenient platform is probably just starting with an LX car, but they’re still heavy, have the independent rear suspension, and still a little too new to skip smog in most states.

Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street
Not a lot of Mopar guys are racers just go to the track.
If I wanted to build a drag & drive with G3, I'd start with Mitsubshi built cars (Colts, Arrows, "Challengers" and the D50) of that era since the automatic versions used a Chrysler-sourced 904 tranny- so crossmember, shift linkage, driveshaft and rear can all stay in place. Maybe a 90's era Daytona or Conquest. Wouldn't need a ton of HP to go fast.

The rings are so high on the pistons for emissions reasons, they wanted to burn everything off. You can find "drop in" pistons for them, or just buy hellcat stuff. NO way would I have a stock 5.7 cranked up to 1100hp on stock pistons. If you're going to remove them to gap the rings, just put pistons and rods in it. FYI that was a gen 1 5.7, the 2009+ Eagle is far superior cylinder head and intake wise, not sure about pistons
