Hi All.

This is probably and old topic that has been question many times, but i cant find my answers, so i post this thread and hope that you guys and girls would have some input for me.

I am building my 1997 LS! engine and i am wondering how much hp the block it self can handle.

These are the parts i have :

Trick Flow top end 515-460 kit.
http://www.trickflow.com/parts/tfs-k306-515-460

Fast 102mm big mouth intake with TB
Lunati 4 inch stroker crank
Lunati H-beam rods
Mahle racing 4.065 pistons
MLS head gasgets
APR head studs
ARP Main studs
Melling high Flow oil pump
42lbs injectors
custom made headers

My driveline
T56 magnum 6 speed
C4 rear end
Custom driveshaft and halfshafts ( not recived yet)

I am hoping to reach somewhere around 700HP

Will the block handle this?? or do i have to go for the LS3 block?

Any info is very appreciated

Thanks

 

Block can handle 700 no problem

 

Thanks.

What if i want to turbo/supercharge it sometime later
Can it handle that or do i need to swap it out.

 

The block is good to like 800 + weather it be n/a, turbo or whatever

 

The block won't like that 4.065" bore you have listed for the pistons though. You can't really go much over 3.905" without new sleeves, and that's about a $2k investment.

 

You aren't going to get 4.xxx pistons in a LS1 block without a resleeve

 

You might want to look for an LS3 block for those pistons or an LQ4 block with a full pour of Rock-Blok to get .065 over.

 

Thanks for all the replies.

Then i will go for a LS3 block later on.

 

Is the signal from cam sensor on LS3 the same as LS1??
