I am fairly new to the LT1 and LS1s im currently building a LT1 and have a few questions. From what I have been told you can put LS1 heads and intake on a LT1.
Main reason I ask is because i would like to know if it would be smarter using LS style on an LT. I plan on doing a 383 stroker turbo'd on ethanol pump gas, and would like to see horsepower in the 500 to 600 range at around 6000 rpms. This will be my first Horsepower engine build so as much information as I can get will help me reach my goal.
I also have 4 years of Auto tech training just nothing on the performance side of things, and currently a Tech as well.

 

No offense, but what kind of tech training do you have, and who told you LS/LT stuff is compatible (hopefully not your teachers)? The LS and LT platform of engines are completely different - the only thing they share in common is the lifters. Using LS1 heads/intake on an LT1 is just not possible.

500-600 flywheel or crank HP? Big difference there. If you want 500-600whp, what transmission are you planning on using? What's your budget? Lots of questions to be answered AND asked. Good luck, and welcome to the forum.

 

Have the basic 2 year tech plus another in special training.
anyways i heard from a couple people in town here saying that it was compatible not to look like a dipshit but rather ask someone that might know a little more about than a couple guys off the street...
i want 500-600rwhp, dont really have a budget i got nothing but time and money to be made during that time. its going into an 87 t type buick regal. going to use the 4l60e trans if it will stand up to the challenge if not i got some thm350s laying around

 

somebody's been pulling some huge tubes...and needs some serious textbook training

 

Dont need anymore training at rebuilding engines. As a tech you dont get to many people coming in asking for this kind of things its usually throw a cam in it or just rebuild it. I know my fair share on engine rebuilds just want to do this high hp build for myself and since its my first lt1 im building I dont know an aweful lot about the design

 

Better start reading up, you have lots to learn about these engines.

 

well the only question you've asked has been answered so welcome to the site!
theres lots of good info on here! start by reading all the stickies, then go crazy using the search feature, then ask all the questions you want!

 

500 crank should be easy enough to do. You can get 600 crank with AFR heads. As with any engine, the sky is the limit for the LT1, you just have to build it strong and let it breathe. A lot of people are going with the 396 build these days. Plenty of reading on this site that answers just about all your questions. The guys here are great if you have a problem.

 

LT1's have some compatibility with SBC's and LS's have no compatibility with SBC's or LT1's other than lifters, which are very similar in all three. I believe the lifters are the only 100% compatible part.

 

This, and welcome to the site.

 

they only have one BIG thing in common.. They are the perfect engine to stuff into an F-body and kick *** on the road..

 

actually u can use an ls1 intake and heads.








u just gotta use an ls1 block. thats all

 

The only things LT1 and LS1 motors have in common are displacement and the same neighborhood of factory horsepower ratings. Otherwise, totally different, incompatible motors.

 

There is a World Motown SBC iron block that is cast so it uses only LSX style heads.

 

LS1's are 346 displacement.....but close. And you CAN use some of the electronics from the LS1's. Heads and intake you can not.

 

i thought they shared similar lifters as well or is that just the ls7? or am i just losing my mind

 

Lifters are interchangeable, this was posted already.

 

welcome to the site !!!! Just a bit of advise ditch the lt1 and go with ls1 all the way IMO

 

Do some research and you will

600hp lt1 but it's not going to cheap
