09 Challenger/Mustang engines

[Chris "drooze" Wertman]

And the Darton Wet Sleeves solve that but at around 5k + block for machine and sleeves by Darton....ouch......(I know a guy who got a price break he did 8 at once, they cut 300$ off each not much of a break in my book.) Turnaround time is about 1.5 months right now.

ALSO LSM Out of Michigan is making Billet 6.1 blocks , obviously no good for Stock, but they are water blocks or solid at around 9k, beats the 10k for a cast and sleeved Mopar 426 (3rd gen like the 1320 had).....

Oh well......its the Rise of the Hemi again....and damm are these motor designs sweeeeeeeeeettttt..... (except the thin castings on the 6.1)

When the VVT 6.4's hit they are going to be downright EVIL, and with MDS theyll get the same mileage as the 6.1 average.....cool stuff.

How many other (and this is a serious question) STOCK SHOWROOM engines (as the 6.1 SRT8 is) flow 300 cfm on the intake side bone stock ?
