Stock 392 scatpack will run 12.3.-12.5, thats impressive imo. for a 4200# car But my GT ran those numbers when I had just a tune and cat deletes. Now that Im boosted im running 10's.
No need, they are happy with sales it seems. But I have seen some 392s with bigger cams and full boltons running 10's all motor same as some 5.0s with full boltons + weight reduction. For a 4000+ pound boat running 10's that's impressive.
All you would need to do is drop in a mild cam and you could easily get 550+ hp....pushrod motors just need dat lumpity lump cam to wake them up. Stock pushrod motors are too tame.
I bought my 13 because of the SRA and retro looks, the best looking of the s197s imo. Its running 10's now on boost. I wont buy an s550 gt till it gets a significant hp boost and more engine tech. Maybe 2017 or so?.....GT350 is going to my stable asap though.
Diff platforms....392 is old school tons of low rpm torque...pulls hard. Coyote winds out fast and pulls hard to redline vs the 392 which runs out of power quicker. Love um both
