As far as engines go. What exactly is diffrent between the two? intake,heads,cam?

 

This thread is already on page 2!!!
But yeah, intake & heads are different.....camshafts are irrelevant, 'cause once you go aftermarket, then an LT1 can have a better cam, but the engine still might not make the power of the LS1.

 

The lifters and the bore centers are the same. Short of that they are different.

 

I found a REALLY great thread on this topic!!! Clicky

 

 

Yea this subject has been posted a billion times,just do a search

 

1) LS1 Motor is all aluminium and 75lbs lighter than a LT1 motor.

2) The LS1 has a 3.6 crank compare to a 3.4 crank in the LT1. To me,making the LS1 a "baby stroker motor " already from the factory.

3) LS1 heads already have 2.00/1.56 valves in them already from GM compare to the 1.95 /1.52 in the LT1 heads (sweet )

I own both a LT1 and a LS1 and I love both of them. The only thing I hate about my LS1 is the piston slap I get once I start it up in the morning. Other than that ,the performance is great. But I'm still an LT1 Man 4 LIFE !!

 

actuallt the lt1 uses 1.94 i 1.50 e valves.the ls1 uses 2.00 i 1.55 e.

 

Exactly.

 

are thoese number on the valvues the width? and the big crank means more room in the chamber?

 

correct.you got the basic idea.

 

cool, i learned alot of wrench turning in auto shop in school. i know that sounds gay but i mean we had lifts and good tools. Great teacher. I was in adv. auto so i mean i was pullin tranny's and rebuilding old engines in school... like high school. Was alot of fun and learned alot. But as far as specs and technical stuff i have alot more to learn. Thats why i'm trying to learn about all the engines, maybe even learn specs on some mustang motors to to broaden my horisens lol
