engine question???
I bought a 97' Camaro LT1 a couple months ago. It is my first f-body i have ever owned. anyway, the kid i bought it from blew the engine and had it replaced with a motor from a wrecked camaro. (warranty replacement). I took it to the local drag strip and i am running a full second faster than stock lt1's. 14.3 compared to 15.3... (elevation sucks) The kid i bought it from doesn't know what is done to it and i was wondering if there is any way to find out if it has any upgrades.. (heads, cam, stroked, ect.)????? any one have any suggestions.

If it does have work done to it, it is most likely simple bolt ons or a very mild cam. You could start by looking for obvious things such as headers, catback, cold air intake ect. You can also pop off a valve cover and see if aftermarket rockers and springs are there.

What kind of elevation are you at where a stock LT1 runs 15.3's? A cam, you would most likely be able to hear. If it was stroked and nothing else, it wouldn't run a full second faster (not enough of a hp gain to do that). I have heard of people porting heads and doing nothing else, which could possibly yield the results that you are seeing. It's just very rare to see that done without a cam and other supporting mods. As for other mods, just do like 2000GTP said and check for bolt-ons.

we race in billings, montana.. about 6/10 of a second added on for elevation.. I can beat stock ls1's no problem. its definetly something inside the moter if anything.. maybe it just runs well..??? i know what bolt ons are on it.. CAI and 170 therm. cat back exhaust also. maybe nothing is done to it but every one that see's it run thinks so.. thanks for the advice though, ill pop the valve covers this weekend sometime. and dont worry im not completely full of ****...lol... i work at a mechanic shop and just got done breaking down the engine in a friends buick, down to the block and back together... so i know quit a bit. just not enough yet...

Which track are you racing on in MT?
A car that runs 14.00 at sea level, will run these times at altitude, based on the accepted NHRA stock class ET correction factors:
sea level: 14.00
1,000-ft: 14.14
2,000-ft: 14.33
3,000-ft: 14.52
4,000-ft: 14.72
5,000-ft (not as high as Denver): 14.93
6,000-ft: 15.14
If Billings, MT is about 4,000-ft, a 15.3 in Billings would equate to about a 14.7 at sea level.
Here's the NHRA correction factors, look at the tracks in Div 6 to see what the altitude of your track is.
