LT1 > LS1? Some ideas why...hehe

A lot of LS1 guys are going with iron blocks.
LT1's are junk and you should all give yours to me, the junk collector.

I think your mistaken. Jeff Green from Indiana (guy who I mentioned earlier) is the sole man who converts Donovan 400 SBC blocks into LT1 blocks.
Check the specs on these blocks you guys are claiming to be LT1 blocks. There is a difference between a Gen 1 and a Gen 2 block.

ok lets say that an lt1 and ls1 have the same horse power and they both r autos. lets say hp is 350. in the 1/4 mile which would win?? they have the same 60f and reaction time. wouldnt the lt1 win b-cuz of the torque curf? i am not trying to star any thing i just thinking!!!

Just fyi, the LT1 GENEREALLY doesn't have a higher torque number or even better torque curve than the LS1. Yes it does come on earlier, but that variable is further complicated by choice of torque converter. You wouldn't choose a converter that didn't put a car below its power band, so saying same converter is not a valid argument. The LS1 would win by approximately a tenth in a perfect world with same drivers, cars, degree of suspension setup. However, if the cars were the exact same weight, They should cross the traps at the exact same time, with the exact same mph. However, I don't fully understand the aerodynamic coefficients of both cars and how they relate to acceleration past certain MPH points and drag-related losses via aerodynamic properties.

When people say that all the new cutting edge technology is coming out for LS1's I smirk. All the 'new' products coming out for the LS1 have been around for gen 1 sbc motors for awhile now. So one could conclude that since you can put gen 1 parts in an LT1, our aftermarket is potentially larger, as long as you have the money to convert things. Just my opinion, however.

the cars are the same but one has a lt1 and the other ls1. same torque. its just an idea thats all i was just think. i just want to know if the torqur cover would have any thing to do with it. i know the lt1's torqur is right away and the ls1's is up the power band. when i see ls1's race lt1's i notic that the lt1 takes off fast and out ahead of the ls1 but ls1 passes the lt1.

these two things doesnt make the ls1 superior. but the opti is a bitch and the heat from iron is redicules. and I really dont agree that the lt1 has a better aftermarket than the ls1. How many sites do your find thats based on lt1 only? But this is like inport vs demestic..... its never going to end. Its all based on what YOU like.. and if it makes you happy go for it. b/c there is always somthing faster.

If you are convinced the opti is so terrible there are alternatives so scratch one "problem" on the second the comment about iron and heat you just demonstrated how little you understand about how an internal combustion engine works. Aluminum pulls heat out of the cylinder into the cooling system where it is waste ideally all heat generated would be kept in the cylinder and used to expand the gasses and drive the piston. Reallity does not allow this though so we have to deal with some heat loss into the block and heads.
I theory I will believe the LT1 using gen1 race parts should have a higher capability but the question becomes when does it stop being an LT1. Do we lump the gen1 and gen2 together since they are frankly SO VERY similar and go from there or do we define it as capable of running a timing set driven waterpump and opti even if the opti is not used for the spark just the optical pulses?
I run into a lot of guys at the strip that blow off the LT1 as junk with some mods over the last few months though my "junk" is getting to be faster than some of the mildly modded LS1s and does so in a Caprice not in a f-body she is gaining respect.
I remember this article one time that said in a typical internal combustion engine you could obtain 80 percent more power if it wasnt for heat escaping but everythign would then be "too" hot so its all about the happy median

Assuming both drivers are absolutely equal, t's all about the curve. One could also have better suspension/tires than the other. Different tire psi, more wear on the tires, different lanes of the track; these are all very small factors. Some LS1s have the ls6 intake manifold some don't. Assuming both had 350 hp, the one with the ls6 manifold would have a slightly different curve than the earlier LS1s with a slightly more aggressive cam and the LS1 manifold. Same goes for all mods.

gotta admint the LT1 does sound a **** load better then the LS1 though.. ive raced my friends and other pepole before there doesnt seem to be to much of an advantage for them though.. maybe mine got touched by god in 98 but sold as a 97 lol
