Re: LS1 vs LT4
89 corvette was the first 6 speed. The 4+3 is a four speed with an overdrive bolted to the back of it.
The 96 vette isnt as light as some of you guys might think. I dont know the exact weight but its around 3400lbs. All 96 lt4's are 6 speeds and lt1's are all auto's
It will be close, as the lt4 is underrated as well. I still say that the ls1 will prevail............

Re: LS1 vs LT4
Correct me if I'm wrong...but isn't the hotcam from the LT4 originally? It is called an LT4 hotcam. So the hotcam is the stock cam for the LT4 motor. I also believe they have a different intake manifold.

Re: LS1 vs LT4
i have a lt4 conversion package on my camaro (the 425 hp kit) i also have all the supporting mods like cai, exhuast, etc.
i raced a 2000 ss auto with hooker long tubes, ORY, lid, free ram air, granatelli mass air, smooth air bellows, and throttle body.
at the time i had a 2800 stalled auto, from a stop i would murder him. from a roll it was pretty even.
since the vette is stock, i think the ls1 will end up in front.... but only barely

Re: LS1 vs LT4
The stock LT4 vettes seem to dyno right at the same 300ish rwhp level as most stock LS1s from what I've read, which would peg the LT4 as pretty underrated.
http://www.grandsportregistry.com/dyno.htm has several stock LT4 dyno numbers, and plenty with mods.

Re: LS1 vs LT4
My brother's stock LT4 Vette made 308 rwhp and ran low 13's@107-108, so it's pretty comparable to the LS1.

Re: LS1 vs LT4
If its for money I'd watch and make sure he's actually stock. Most Vette guys I have seen rarely do much racing, but one reason to start would be having trick up their sleeve.
Can you confirm that its bone stock and does he know your modded?
