there isnt any difference between 305, and 345 in the LS1 world
The LS1 was very under rated from the factory to begin with. The C5 just has a 345 hp rating because, why would they rate a F-body the same, that cost 15-20k less?? Its all about sales…in that post you made, it even said the LS1 in the f-body and the C5 are the same…but why would one have 40hp Less? Sales. C5 was gm’s highest sports car.They couldnt have a 2nd entry level pony car popping in with the same hp rating for thousands less…then no one would buy the C5.
but once they started hitting the dyno’s, LS1 f-bodys stock were putting down the same power as c5’s if not more…and that doesnt include the 335-345hp SLP package camaro’s and firehawks.
