I was thinking. you know how there is all these companys working on ls1's that started with lt1's or older like mti. What kinda power where they making with their lt1's. anyone know?

Lswonder

anyone know?

Vendetta

work on the LT1 has progressed. It's not like they had faster LT1s, but they disappeared with the creation of the LS1.

Lswonder

I know its progressed i just meant how much power where companys getting out of new heads cam lt1's. I think its sad that companys are starting to exclude the gen 2 out of their product line up

I've seen around 440 whp on stock ported castings. I've seen well over 500 with ported AFR/SB2.2s, still hydraulic roller

Lswonder

AFR/SB2.2s?

The old/big stroker motors for MTI with heads and the cam of your choice were putting out around 425 o 450 if I remember correctly. LT1 motors have advanced greatly since those times, and now we have LT1 heads/Cam combos making that, but the LS1 market is just so huge that many performance shops would lose money by introducing an LT1 lineup. Most of the people who own LT1's nowadays are younger people who couldnt afford the LS1 or had too much money in their LT1 to give it up and have little left to mod on it. It sounds bad, but its the truth, the people who have a lot of money to spend on modding cars will generally have the LS1 because they can afford it while people who dont have much to spend on modding but want a decently quick car have to go with an LT1.

Lswonder

but if u put a decent amount of money in a lt1 it can still produce big numbers like lil brother ls1 correct?

Vendetta

Definitely. In fact, the more you mod, the lesser the difference becomes. The LS1s have a lot of advantage, stock for stock and bolt-on wise. However, their main advantage comes in their stock heads. Once you replace the heads on your LT1, you'll be able to put out almost equal amounts of power. It's a general misconception that the LT1s are weak, old-styled motors. But when massaged correctly, they can be as powerful as the young LS1 motor.

Gangly

Correct...you can now see huge numbers out of heads cam combos on the LT1 just like you do on the LS1. But you will never see the same amount of HP out of a cam only LT1 that you would see from a Cam'd LS1...like Enisguy said, their heads just flow too good.

LT1'S ARE STILL THE KINGS

I have to agree...
my ported iron heads with a CC305 cam made 393hp, 420tq to the wheels.
Now with a custom grind cam and much higher compression, LS1's don't stand a chance.

I will stick with my LT. It is stout and even though it isn't a 6 bolt main (LS), it is plenty strong with a four bolt main.

blkformula95

ok so im gathering that if i use stock ported heads, LT's and say, a... CC306 thatll give me say 390-400 and ls1'sd eat my dust??? im educated on LT1s but im not too familiar with LS1 mods

Vendetta

Well, a stock LS1 would eat your dust. Modded LS1s are monsters thanks to great flowing stock heads. LS1s can put out 400 rwhp with just a cam and bolt-ons...

A modded one would too if he was putting down less power. I know guys with bolt on LT1s beating stock LS1s.

I remember people with six speeds, if they had ported heads, a CC306, Long tubes, they were making like 400 at the wheels and that was the ****. Even when the LS1s came out, they werent faster than LT1 cars for about 2 years or so. So most people kept their Lt1 cars because they were out running the LS1 cars hard. Like I remember the first 382 L1 were like 12 sec cars at best. Then around 01 I guess, the LS1 started making over 400 at the wheels and it was all uphill for them and down hill for LT1 cars. Back then theres was a lot of stout *** blower LT1s making big power and running good. Even in comaprison to today, Gary Neal, Dave Lewis were all making 700+ at the wheels which even today is a lot of power. MTI had a couple bad *** blower LT1s, John Campbells was one of them. Then they had the fastest Impala SS for a while. They also had a guy make 415rwhp h/c back in the day like 97-98. The LS1s were getting smacked around hard untill about 01 then they started getting faster and faster. If you look at the old Chevy High Perofrmances, from the mid 90s, Lt1s caught a ton of fan fare and saw some R&D that never came about. Like edelbrock was going to make an intake and cam for them but never did. The Ls1 left the performance market scarmbling. I guess because we got MTI and mad man in one town, Houston saw some nasty *** LT1 cars that were just monsters. There was a guy with a white c4 he was making 800rwhp on nitrous n a 396 LT4 and he was bitch slapping trailer cars. I guess I came of hot rodding age when the LT1 was the thing to have, so they always left a amrk on me. That and MTI is liek 5 minutes from my house so I saw some nasty LT1 cars come out of there. Ah good times good times

Still some die hard LT1 guys in the midwest...force fed mainly... 8s, 9s and 10s... Enisguy and Bizzzatch350 hit it all on the head..

Dave Lewis' 95 Blown/Nitrous 383 LTI Firehawk is probably the most powerful f/y-body MTI ever produced, and still sits outside their shop regularly. Last I heard it dynoed something like 980rwhp.

That car makes great power for what it is, the car still has a CC305 cam in it, stock 95 PCM thats been tuned and it also runs a T trim blower with a vortech after cooler. It poped a head gasket, they put new heads on it then it went over to a TH200R4, its been tranny issues since. Put in a bigger blower cam, good after market computer and a bigger blower like a YS, that car would rock. Its a N20/blower car right now, I just wish they get the tranny right and take it down the 1320. The old head tech Jeff had a twi turbo 5.0 Mustang that made more power than Daves car did. I dont think theres one person in Houston that doesnt know about that car. Any one else that car would proly have been wrecked a long time ago. It was making 790s with shorties back in the day. And to think up untill a year or two ago, that car had stock Lt1 brakes, it has some Baers on it now. Out of any car MTI has ever built, that car is my absolute favorite.
