Did you know that the firing order on the LS1 was revised from 1-8-4-3-6-5-7-2 to 1-8-7-2-6-5-4-3 ?
Also - the LS1 is 44lbs lighter than the LT4 used in the C4.
The 1998 convertible weighed 114 lbs less than the C4 convertible, yet it is more than 4 times stiffer torsionally.
That's all I've got - and it is courtesy of the Corvette Black Book by Mike Antonick.
Didn't they go back to the normal order after 97 due to the syncopated exhaust note it had??? I swear I read that some owners were not happy with the off rumble of the exhaust...so GM changed it back to standard after 97...it was in a Corvette History book I have...
