Default Hemi stats

info needed that im having trouble finding.
first, are the 5.7 6.1 6.4 blocks like any other dodge motors? my tuning software gives me the SB options of 318, 340,and the 360.
intake cfm's at 1.5inHg if anyone knows(a rough guess would work i dont care about the location at which this is tested).
stock cam information (intake open and close, exhaust open and close, lobe center, duration, lift, etc etc etc) intake valve size in inches.
intake style. etc etc etc.
compression ratio's(9.6:1 i think, whats the 6.1l's?)
any and all would be nice.
i use simulators for engine building and this is my first dodge as many of you may know and my software is too outdated for this engine. so im building as i go.
also any and all cylinder head information would be great.

The 5.7 and 6.1 are a far cry from the old Mopar small blocks. Stock cam info for what year and application? Same for the compression ratio.

2005 5.7L and im not sure what year the 6.1l cam came from. so its a completely new block though, its not from the 318 or 360?(i knew it wasnt like the old but if i post so ignorance like that i can get someone to reply lol its trully not even a hemi based on combustion chamber shape)

it's not just the block design but the pcm's themselves...it's like night and day in terms of tuning between the 2....

No, they are an entirely different design than the old MOPAR blocks.

The 6.1L engine first came out in late 2005 model production and was ground specifically for the 6.1L performance target set by Mopar. Not sure of the specs but there are a lot of stock 6.1L cams out there on eBay and other sites that specialize in the Mopar LX platforms (Charger, Magnum, 300) and LY platform (Challenger).

Good luck with your project.

ive already got a 6.1l cam. im trying to find the best way to complement the 268H im getting. i have some simulation software but its too dated for this motor and i was trying to find somewhere to start. i need to know my 05' rams cam demensions. and the CFM's our intakes pull. i can tune it between 300-1100 cfms so i need to know where our intakes stand stock so i can pick the right intake and throttle body.
