Sorry For The Question, I Just Wanna Know What's The Primary Difference Between The Lt1 And Lt4??

If Somebody Could Give Me A Quick Run-down, I'd Appreciate. Thanks.

 

Just afew things..
Cam
Heads
Rockers
Timing chain
Intake
4 bolt mains

Think that about it.. Why do ya ask.. Whatcha looking to do?

 

WELL i'M STARING WITH BABY STEPS, ONLY GO TTHE K&N, RECENTLY INSTALLED THE CC305 AND I'M LOOKING AT 1.7 RR AND MAYBE PORTING THE CYLINDER HEADS, I HEARD THAT 2.02 1.60 WOULD GIVE ME NOTICABLE POWER, WOULD YOU AGREED.???
I'M NEW TO THE PERFORMANCE WORLD AS YOU CAN TELL, BUT HELL IT'S ALOT OF FUN !!!

 

The 1.7 rr's might be a little too much on top of an aftermarket cam. A set of 1.6 rr's would do the trick though. As for the heads, a port and valve job will unleash a good deal of power. Lloyd Elliot or A.I. both do port work for reasonable prices.

 

My LT1 has factory 4bolt mains. Check this out for all of the differences http://www.fierolt1.com/lt1_vs_lt4_1.htm
