5.0 any day of the fucking year dude, GM's cars have gone to shit lately with exception of a few cars. the camaro feels really plastic and cheap, theres almost no feeling of connection to the road when driving one, roadnoise is shit. the average ss1 1/4 is around 13.5 with a decent driver. slow compared to the 5.0's low 12 run. I've test drivin both cars and stang is 1230481740 times better in every way, the chassis is super tight, transmission is great, engine is ridiculous. people are getting the 5.0's into the 10's with bolt ons, a clutch and drags without even having to strip one thing for weight savings.
lets check the interiors
Camaro ss
5.0
thats interiors from both respective trim levels, cmon now
i know the GM guys are having a hard time getting raped this time around, but its time to face the facts this time, Ford takes the cake here. and its cheaper.
and just for fun:
I dont see any camaros still running stock LS3's doing this.
