So I was on anather forum, and the guys there were talking about 10 sec LS1s that were cam only, then they pointed me to this thread on LS1 tech:

Is this for real? maybe I should just go ahead and concede victory, lol?

 

The fastest cam only LS1 is in the 9s I believe

 

from the curb weight, some of those cars are clearly drag-only.

#2 and #3 on the list are less than 2900 pounds. some of the ones with heavier weights are still flying though.

 

I believe the cam only record is 10.2. However, your average cam only ls1 is lucky to hit 11's. The cars running really fast have thousands upon thousands of dollars dumped into them and they are very light.

 

That's not necessarily true. A buddy of mine just bought a 99 Z for a hell of a deal and it only has minor bolt ons and the engine is cam only and he's running 11's. He DOES have a 12 bolt, but I would think you could at least get really low 12's without it. I wish I had an LS1

 

a 10.2 @ 130 is impressive. scratch that, its damn near godlike.

I don't think thats entirely true. since they said cam only that means they have no other internal engine modifications, which gets expensive. They don't have super expensive $7000 427 cube short blocks with $3000+ heads. Weight reduction isn't incredibly expensive. Alot of it is free. I'm sure they have some money in a good rear and clutch/converter but so do ALOT of other guys that hit the track.

I would also be willing to bet that a cam only LT1 could make its way on to that list with all the weight reduction and a well thought out setup.

Now, if you want to see even more impressive...

theres a STOCK INTERNAL LS1 in the 10s.

 

LS1's with low weight and LG's or a T-rex cam, holds the top 5 all time cam only LS1 records. The Cyl heads in stock form are quite sick...... it makes me want to throw up.

 

Whats the Fastest cam only LT1 Car?

 

Wow, I have $10K+ in my engine and *hoping* to drop a 10, jeeze. I would hope my LE ported trickflows end up flowing as well as some stock LS1 heads?

 

WTF bolt on olny LS1 - 10.9 E.T. - I QUIT! LOL

 

LS1's are retarted, nuff said.

BUT I like the fact people under estimate me and we do have a street racing scene. Not many people are toting around their cam only LS1 timeslips. So I stand half a chance when my car is finished and has n2o. Technology does move quite fast.

 

Don't forget those cars have a lot of money tied up in suspension parts...a lot of money. Tubular K-members aren't cheap, nor are the light wheels/tires, etc. There is a lot of money in that low 10 second cam only LS1.

 

The fastset cam only LT1 I'm aware of is Frank95Z. He ran an 11.2 @ 118.9.

 

I think one advantage the LS1 has that is being forgotten here is the factory pcm allows it to rev higher. For a track only car you can really make revs work, yes the heads are better and the aluminum block is lighter but I think this important as well.

 

but plainly put, be it just a motor change from a Cam only LT1 to a cam only LS1 with the same suspension, weight, tire, etc etc LS1's are faster.
