Wanting to go with a 230/236 510/540 112lsa
I have long tubes y pipe catback cai, gonna get a reprog on Madz28 pcm

Do I need roller rockers or will the stockers suffice? what about a TB or injectors?

and Does the intake need to come off on LT1 to swap the cam, it would be sweet it if it was like the LS1?

 

you should be fine with the rockers you have.

but you will have to change valve springs, stock are only good to .525" or so

you would proabably gain a little if you upgraded the TB and injectors, but i don't think it's absolutely neccessary

 

Spring will have to be changed, and I think the stock rocker might have to go because the slot is not long enough to support high lifts, and you can get into interference with the larger springs. You could check into changing pushrods and lifters if it's high millage. I recommend, you go with 30# injectors and 52 tb.
Yes the intake manifold must be removed.

Yes, the intake must be removed to access the lifters.


You would like to remove the heads?

 

Is it an automatic? If so, you need a stall. What gears do you have? You can run on 2.73's if you want, I did for awhile but the 3.73's are BY FAR better! I also ran on the stock fuel injectors and still run the stock TB.

 

[QUOTE=Built on Sin]Don't have to remove the heads on a ls1

 

ya my main thing is can I run stock rockers still?

it's a 6spd so i don't have to worry bout that

my main question was Rockers so is that a must change?
