definetly not toying with a 383 anytime soon, but a decent shot might come into play if all else fails.

If you understood the difference between the two it would.

 

I'm not blind.

 

 

The flow of the heads is a big advantage of the LS1...also those engines have much better breathability.

You probably won't beat your cousin...sadly to say, alot of us LT1 folk wouldn't beat him. Another thing to get the LT1 to peak performance is to get it the most air it can. Read about how the LT1 engines in the Corvettes are tuned and stuff. But you can do the head work, a better cam, headers, exhaust, tune it in and it'll rip. Otherwise...you better hope he can't shift worth a damn...lol jk

 

I really don't understand what everyone is talking about. Theres NO possible way for the LS1 to be faster than the LT1. Why? Because of the ignition system! Now I know what you may be thinking "now wait just a second there ironxcross, the ls1 has coil packs per cylinder and was created by god himself".. and you'd be right, BUT the lt1 has something better - THE OPTI. It was created by the devil, so its got more power... obviously. It automatically[ (key word here) adds 300 rwhp. Add that to the rest of the motor (275-285 hp, depending on year) and guess what.. you're in the 9's. And thats with BAD traction.

Now I know what you're thinking now.. but ironxcross why do i still run 14s? Now calm yourself children, I have an answer for you. Government conspiracy. I kid you not. The government pays all drag strips to put in anti optispark emitters.. and you know what they do.. CUT YOUR HORSEPOWER IN HALF. THATS the real reason you run a 14 something, or a 13 something with bolt ons... the government.

Now how do we solve this. Simple! Wrap your opti COMPLETELY in tin foil. I don't care if the balancer is getting scratched, you'll be fast like the devil intended! Please, if you have any quesions, be sure to PM me, I am here to turn the tide against the evil government forces and their LS1s!!

 

Are you related to Gripenfelter?

All kidding aside the LS1 is pretty good. But it's not just about the better flowing heads stock, intake manifold, and weight. You have to realize they have shorty headers stock, 1.7 rockers, and a far better inline air intake system. You buddy also has the LS6 intake on his car giving him more of an advantage than LS1 intake'd cars.

I'm not trying to start a flame war, but you give a LT1 1.7's, shorty headers, and a LS1 style cold air intake and I bet it would be darn close in the 1/4. But thats just what happens, new gets old, and things evolve.

Since your main objective is the beat your buddy make sure you read up on what makes you faster in a race. Mdacton can back me up that it isnt just about HP and TQ. It's about your complete setup. I used to watch to local Fbody 400-500hp guys beat up on 600hp+ Cobra's at the track cause they couldnt get their crap to hook. Tires, gears, suspension should be a focus too. You might want to keep that to yourself if you want to be your buddy.

JFYI the ls1 is the new LT1 compared to the LS3. 390rwhp stock > *. Good thing all those parts are interchangable in the LSx series.

 

 

i thought you guys would like that.

 

you guys a discouraging me, gonna make me go out and buy a 98+ ss. So the only way to catch up to him would be a totally set of new heads? and even then im behind the 8 ball? For some reason i don't feel that huge of a difference from when i was driving my car from when i drove his besides his short throw.

 

The LS1 is a better motor period. I have one that is modded and I have destroyed lightly modded LS1's. But there is a silver lining, the front of my car does not look like this:


Or this:

 

Dont get discouraged we are just being realistic with you. You might edge him out of the hole, but he'll reel you in slowly with his top end. Your modifications will cost you less so buck for buck you'll probably be ahead. Many SBC parts are interchangable with our motors, valvetrain, bottom end, etc. I have a buddy who owned a nice heads and cam LT1 car but sold it in a pinch. He knew the LS1 was a better motor so he bought one. About a year later he sold it to get money for another LT1. I wont be getting rid of my LT1 for a LSX anytime soon. Dont worry, I bet your car is a nice peice and I'd keep it if I were you, but be realistic about where you stand, just dont under estimate yourself.

We'll help you stay a step ahead.

Well, something to consider is that he could have all the power in the world and this super duper XYZLTR-whatever motor...if the guy can't drive as well...more to say Drag Race...you can probably out run him with practice, tuning, and suspension mods.
We're all in it for fun anyway! There is more to racing or beating someone than LT1 vs LS1...big blocks are still fast right?
