That's a Magnuson style, I need to ask what fuel and what's the designated intent. If it's pump gas and mostly street you should be fine.
My turbo big block is 12 to 1 but it's race gas. C-16. It has no detonation at 30PSI NOT a Magnuson style...The factory supercharger and the Magnuson are completely different from a design perspective. Magnuson uses roots style rotors from Eaton (same as an Edelbrock supercharger) and is far less efficient than the IHI screw compressor that comes factory.

OP: Why aren't you going with a factory longblock?? There are guys running a nitrous plate setup just aft of the throttle body with a smaller pulley and Diablo tuner running 9's in a factory weighted (~4500#) hellcat! You don't really need any more stroke; just add boost. The factory stuff is pretty dang stout and for the price of a longblock, you might be wasting money going a different route.

Hope I helped a little. The Challenger is for sale. I got bored with it and don't want to take the drive ability out of it with a,stroker and such. The wife can get in it now and drive it to the grocery store lol.
I like your build, your going to have a fun ride. Is this motor going in the Hornet? You did, Thanks a lot! The car is a 68 Charger. Pure twin h power for the Hudson!

I bought a bare block before the short blocks were available. I also have a bunch of different Gen III internal parts and figure I could get something to work. Here is what I have: New factory 6.4 crank New Factory Hellcat rods and Pistons Manley 300m 6.125 2" journal connecting rods Manley 4.09 bore platinum series pistons Good stuff but it's kind of like legos that don't match lol. Figure whatever way I go I will have to buy something.

I think with the Manley pistons and rods you already have, might as well go with the Manley 4.05 crank. Dont know your comp height on the pistons but if they're the 1.09" that combo will work to but compression will be higher.

Ok, sell what you have except for the pistons and do the 398" deal with the 6.20 rods. Would be a killer,solid combo. That is exactly what I would build, except my broke a$$ would be using a 5.7 block.

My son is getting ready to start his 6.1 build. It will be boosted not sure if spray or turbo but leaning more turbo. FI w/Megasquirt. What do you think the power limits are with the stock crank using aftermarket rods and pistons? thx matt

From what I have read, srt cranks are good to 1000hp. The factory oiling is what does them in at high rpm.
