I've seen 6.4s make 500whp with head and cams, but 51whp more is 51whp more, 658 na crank horsepower is impressive.

I'd eventually like to do a 454 Stroker on my Scat Pack lol. Surprisingly it's not expensive on yall's site.

[Crash]

MMX ROCKED my 392 dropins, cam, Whipple and supporting mods.

I like the supercharger for the track and the naturally aspirated for the road

[tarmonkelling]

I'm in the middle of a 426 stroker build on my 14 Shaker but is a Arrington claims it will do 514rwhp 600hp at crank but a hell of a lot more tourqe and of course who tunes it makes a big difference in the end.

Nice build, what’s your fueling ? I was thinking the same N/A build but going with E85 for a bit more power?

[terrellector]

Can you guys make like flat plane crankshaft for the hemi 5.7

[brewaire]

Great build! What's your opinion on the Mopar T/A cold air intake?
Good as any aftermarket ones?

[bryanunion]

i thought flowmaster mufflers were restrictive

[Chris-zmwh]

Considering what can be done cam only on a LS7 these mopars really arent impressive with out boost

[zoryb]

This probably damn near a 15k build. With no boost. And only 550 wheel? It’s fbo scats pushing 530 540. You would think a stroker kit would ATLEAST have you in the 6’s or 580s 590’s minimum
