I have been eyeing this option but also doing rods and pistons on what I have since it would be stronger.

You could call East Coast Moparts and ask them what's different, Andy and team would know.

Later year Hellcats got some improvements (2018 and up I'm told) which make the motors stronger, and Demon/Redeye stronger still, but they're not bullet proof. A professionally built motor is always the best bet if you wanna lean on it IMO.

The numbers I've heard are 850rwhp for a Hellcat (and a Redeye too) but I think the Redeye can take about 100rwhp more. Beyond that you're rolling the dice I think.

Has anyone been able to successfully order one of these long blocks lately? I’m not a Redeye/Demon owner (so no VIN), but was hoping to pair the long block with a Redeye/Demon supercharger that I bought for my 70 Cuda swap.

If I were to guess, I would think the difference would be the regular vs. Redeye bottom end...better cooling oiling in piston lands and stronger construction of bottom end...my..02

I have a 2017. What engine changes did I miss out on?

I'm told the rod bolts were upgraded to ARP and some other small changes like oiling improvements.

@BULL PN P68436298AA - not sure if the P matters but it's at the beginning of the PN decal on my driver valve cover.

Also, just checked pics mine didn't have manifolds but everything else.

Did it include an oil pump? Or Oil pan?

Did you guys get your Hellcats running? Any problems? Did you need to install an Oil Pump?

I’m no professional but my home built engine sure performed well in Texas.πŸ˜€

If you enjoy building engines and wanna take the time nothing wrong with that. With what proven made to order short block costs wouldn't really be worth it for me I don't think. Maybe on a different project one day.

I hope you do and keep good notes. Will help folks a lot I think.

I know Demonology pushed his original Demon engine pretty hard. It eventually lifted a head and when disassembled reportedly had 6 bent rods.

Do you know how hard he pushed it? I'm really wanting 8.6 no spray stock blower. The guy claming fastest bolt on is spraying and is in the low 8.5s for a pb in houston. Has a @hellno trans. I may need the trans as mine has a lot of passes and still stock. My changes will most likely get me a solid 26psi. Hopefully long tubes drop that a little. I see close to 23psi in good air before with 2.85 10 lower and stock tb not ported. Adding ice tank which will allow me to go to a 2.75. Bearing plate and the sdg sount with a 108tb. Good chance it will equal more than the 26psi. Id like to stick around 25psi with the long tubes or no doubt I have issues. Even at 25psi its a time bomb. Just need to get through April before I make bigger investments. I could bolt the heads down pretty cheap if I didnt go arp 625s. But even then......
That and I'd like to put some lengths on @fumanchu182 before doing anything extreme. :ROFLMAO:

He pushed it pretty hard. I wanna say 2.75 upper, 10% lower, ice tank, blah blah, and nitrous but never heard how big of a shot. He was cagey with time slips but it was in the 8s for sure.
