I've been impressed by the performance of the Gen 3 motor, but dollar for dollar can it match the old hemi?

The Gen2 hemi will always win the wow factor hands down! But, I'm going to use the Gen3 for my new car. I want to use new technology (electronic injection, computer/distributorless ignition). Time to keep up with the times.

The dinosaurs didn't change with the times...and look what happened to them!

I say Gen III. I obviously have a swayed opinion on the topic though.
Can you have power adders? Tell me more what your class restriction are. I'm running a 6.1 with forged drop in pistons(stock forged crank stock powdered rods), ported heads, custom cam, TTi headers, and a Kenne Bell supercharger 10 lbs of boost. Making approximately 640 to the wheels. I'm at 3200 lbs as well. that puts me in the ball park of where you want to be. If I had better rods I could turn the wick up to 18-22 lbs and make so monster power, but my build was a so called budget build. I have close to 18 in the motor and power adder.

I know tons of guys running new Chargers, challengers, and 300 that are in the 10.5 range and they are 4400lbs. One of the guys is running it N/A alumin block 46X CI motor. The other are NO2 cars, etc. If it's a budget build just get a short block like my 6.1 port the heads, change the cam, and put the bottle on it and you will make ur number.

I chose to go supercharger b/c of the wow factor.

Ok I will clarify this a bit more. First, this IS purely hypothetical, nothing I will be doing..........at least anytime soon. No power adders here, just heads up, pure motor, cubic inch to cubic inch. One thing that appeals to me about the Gen 3 is the weight as compared to a Gen 2, also the size makes it a winner, but I'm still interested in the best over all performer in this comparison. I'm in no rush to do either cuz I know that every month that goes by the Gen 3 will have more and more available, but the possibilities are already impressive.

BTW, what is currently the largest displacement you can achieve with the Gen 3?

The G3 weighs at least 200 lb less than the G2. You said cubic inch for cubic inch, which I take to mean no humongous elephant motor competing with a 430 inch G3.

30 years ago, a friend of mine ran a 433 bigblock chevy powered camaro into the 9s. I bet the latest Hemi heads flow better than the old rectangular ports, and the new "Hemi" chamber is much better than the bbchevy open chamber head which had to have a mountain range in the middle to get compression. That camaro weighed in at around 2950 lb. I don't think a 433 inch G3 Hemi would have any trouble laying waste to that car, meaning I can't see why you couldn't get into the 9s normally aspirated using a stock block.
Now you could also do it with an elephant motor but the $$$ would indeed be more and you'd have more problems with weight transfer, engine fitment, etc.
Just my

Just for s n grins we weighed our Gen 3 Drag Pak motor and it came in at 460 lbs. Our Gen 2 426/484 stoker with K heads came in at 720 lbs. With the new Gen 3 aluminum block could put 468 cubes down to 370 lbs.
