the fastest of the 305's were the 5speed 1LE's, and usually 1.5-.2 tenth behind is a G92 305..only because the weight...an EXPERIANCED driver (launching and shifting) will be able to crack a 14.5-6....ive ran low 14's (1's and 2's) with 150 worth of mods and me trying to break it, it went from 14.8's 100% factory, to 14.12 with a K&N a flowmaster and a free mod...
heres a quick run down of the times to expect for a car driven to its "limits"

non G92 LB9 5 speed....3.08.....15.0-2
G92 LB9 5 speed...3.42 gears..14.4-6
Non G92 L98...2.77 gears....14.6-8
G92...L98..3.23 gears....14.2-4
1LE L98...3.23 gears...lighter weight...13.999-14.1
1LE LB9...3.42 gears...lighter weight...14.2-4


im not pulling these number out of my *** lol...ive seen enough fast and slow ones to know whats to be expected when driven properly....as you can see stock for stock both the G92 cars are well matched and it is a drivers race between them...i can count the number of 2.77 geard L98's ive wasted....thatll probly **** some guys off

the 083's are the L98 heads and they HAVE been worked extensivly and flowed 268 cfm....the 081's which i assume your talking about are the centerbolt (87+) LB9 heads...there essentially the same as the 416's.....they have been worked to fit 2.02 1.50 valves and flowed right around 240...not to bad if you ask me...


What was the question again?
