I own a 97 Z28 30th anniversary with an lt1 and have been looking into pulling the motor and converting it into an lt4. i was wondering what are all of the differances between the two? are they 2 different blocks or are they the same? i do know that the intake injectors and cam is different but is there anything else?

 

the blocks are the same. just about everything else is different. i think you can do better with what you have for less, the lt4 cam is not that great. if you can get heads and intake for cheap its not a bad way to go, you would want to have them p&p'd to realize the gains needed to justify the change. why not get a le2 job done on the ones you have and pick a cam for your needs from the selection. not hard to get 400hp. lloyd is a class a power maker look the site over and if your interested give him a ring and tell him what your wanting and he can set you up.

if youre willing to go thru all this trouble you can do alot better im with craby on this one

intake and heads are different. and as craby said, you can make a hell of a lot more power with porting

 

its correct now haha

 

its still wrong, lol

 

I've been trying to send a PM to cravy and gravy

both are being rejected. What am I doing wrong?

 

whos cravy???

 

im not wanting to make power im wanting to make an lt-4 ss anniversary i just needed to know if i could use my block and other pieces of the lt1 to save money.

 

i see the "v" is attractive to some of us hahaha let me go back in there
