LS1 vs. LT1 ok, say if you take an LT1 and an LS1 and put $8,000 into each, going with the best parts that give you the most power gains,big cams, good heads, and etc. Which will be faster?
Can a LS1 with just Heads and Cam have more HP then a built LT1 383 stroker with H/C setup?With both LS1 and LT1's haveing a big cam, and good flowing heads...which one will come out on top

Stock they have their pros and cons ill mention what I can off the top of my head im really tired
LT1 pros
Iron block-Nice and strong lasts very long!
Reverse cooling
350ci
Less $ to mod
LT1 cons
2 Bolt
Opti Spark
LS1 Pros
Aluminum block-100lbs lighter then general ISBC
Techincally Shorty Headers outta the factory
Intake/Heads
Coil packs
6 Bolt
LS1 Cons
Aluminum Block
Piston Slap
The LT1 is still great in my motor, especially a 383 LT1 thats what I am building once my motor gets old. It doesnt matter what you drive, its how you drive and how much money your willing to put into your car. Ill never part with my LT1, or LS1.

what he said.
not against LS1, its a great motor.

This subject has been beat to death. The LS1 is a better motor mod for mod as well it should be, theres nothing wrong with that. Once you start dumping big money into any motor it starts to level the playing field. Give me enough money and I can make a Festiva see 11's. As for swapping, it's just not worth it unless you just happen to have everything for the swap and plan on doing it yourself.

just may be me but i think a LT1 described the way he did "built 383 LT1 with big cam and good flowing heads" would make more power than a H/C LS1, you give the LT1 better heads (weak point), along with the big cam and more displacement i think it would make more power, of course i may be wrong but thats just what i thought

You are wrong. LS1 was touched by God and the LT1 cant ever beat that.
Seriously though, LT1 for MAX EFFORT! and LS1 for DD/street-strip type things.
At low speeds an LT1 and LS1 will feel close to the same, if not the LT1 giving a sense of more "torque" feeling. At highers speeds, meaning above 50MPH the LS1 will really start to make the LT1 look like a smoker at a track meet. (Heads). Both are sweet motors. I have an LT1 but I would be crazy to not want an LS1 as well. Win win no matter witch one you go with.

0-50 I had the guy by 1/2 off the line. 50-70 he put 2 cars on me.
me 95 TA 2.37 A4
him LS1 TA A4, MILD bolt-ons (lid, shitty tune (handheld) runnigh REALLY rich w/no cats.)
There are some freak LT1's out there. I raced a stock LT1 c4 with my stock M/6 LS1 which is a factory frea.. and baerl nosed him out..... LS1's have a better top-end as far as the track would go....but the LT1's have bas-*** low-end power

lol you are a silly one. LS1 blocks are sleeved. people who buy the iron blocks do it cause they can't afford a well built aluminum one. The LS1 is the superior engine. LT1s are SBCs with crappier ignitions and improved cooling systems. that's all there is to it, Gen III/IV engines are more advanced and more efficient.
