**600hp sbm block limit? Or is it bs!!**

How in the heck do the viper heads benefit anyone running an 8 cylinder??? Your comparing engines offered in everything from trucks to performance vehicles to an engine offered in a higher end sports car

LS engines are WICKED....So are the new Hemi's...problem is that the LS stuff has way more aftermarket support, whereas the Hemi's still aren't there yet...IMO the 3G's have more potential then the LS stuff in all out form considering FACTORY head castings

Forget that you missed the quote and answer to the quote and totally missed the design... pay attention to the design and see the ls , other than the viper head having 5 chambers and the ls having 4, notice the copying of the design with such slight changes as to not be a exact same head minus a chamber
The viper heads design benefited gm.... is what you missed. Whereas as usual mopar dropped the ball, gm doesn't.
Instead of the W tech making it to production with the vipers heads, it gets lost for anything else... Typical mopar screw ups, they should have scrapped the 4.7 and kept the V-10 design scaled it back to 8 and 6 and continued with that.

The hemis are fine as for the heads, problem is the fat they're dragging around and the tuning.

I said it is the same old mopar issues, they worry about 1 thing.

W-2 are there, theyre called 5,7,8,9 now, other than the R9 the others are all W-2 base design
I see n/a W motors in the 8's, thats more than 700hp
