Whats going on guys?
I have a 2012 Challenger RT that I had a Whipple 2.9 supercharger installed last year on a stock block. Earlier this year I threw a rod through the bottom end so its time for a rebuild. I am now in position to get this project started and would like some advice and insight from you guys about the right way to do this. I am currently looking at the 345 to 392 Stroker forged bottom end from HHP as well as a comp 274 cam package. My question is would this combination with my Whipple be the best option for me? is there anything else that I should consider? any help or insight would be greatly appreciated ...

thanks

I'm sure some others will chime in with more specific details, but when my motor gets some more miles on it (currently 62k) I plan on putting in a forged 6.2 shortblock with Big Gas heads and aim for 10-11lbs. It's my daily driver for what it's worth. I believe you can get a shortblock for 5-6k no core charge. the heads can range from 1700 from a2 or 3800 from modern muscle so i'm not sure what the difference between them is.

FYI - the 6.2L short blocks are discontinued. You maybe able to find some existing stock though, I was but that was more than 6 months ago. :dunno:

I could be wrong, but the hellcat shortblocks are discontinued, but that doesn't mean you can't get a proprietary one from MM or other vendors. Might be an extra grand or so but may be even better than the HC version.

Yup, some vendors have there own version but I was referring to the OEM 6.2 shortblock crate which used to cost less. For example:

Whichever you choose, you may want to have a conversation with the shop you’re thinking about ordering from about the cam- depending on what you want to spend, there may be better options out there besides the 270. A more blower-specific grind might be the way to go, but depends on your goal.

It may actually be cheaper just to go without a hellcat factory cam instead. While there are “custom” blower grind out there from a few places, you may end up paying more to get it and make it play nice with the Whipple next tuning. Not saying “will,” but it’s a conversation to have when ordering everything else. They may have some recommendations depending on whether or not you want to do head work or not, etc.

Cheers,

Chuck
