how far can the cylinder walls be bored on a 98 ls1, what else should i be looking at doing while i am rebuilding.
already am planing on cam install, oil pump, bearings, seals, gaskets ect. planning on using stock crank, what all can be done at a reasonable price for parts as im going to be doing most of the work?

 

I think to 3.910 or 908 but I wouldnt go over 3.905.

 

I agree you don't want to maxit out. If you want bigger go with the 6.0 block.

 

yep. agreed.

 

so from what im seeing then if i do a stroker kit then ill be looking at a 383 max or can it go bigger, if i am going to do it then im going to go as big as i can displacement wise!

 

the biggest is a 39(3/7) it's a 3.905 bore with a 4.125 stroke made by eagle... I

 

if you want big go with a 6.0 block,or if you want more get a ls7 or lsx block

 

will the tsp 5.3 heads fit on a 98 ls1, wil the ls6 manifold bolt up to them or is there a different manifold for it! now i am just thinking of over hauling the motor, tsp stage 2.5 5.3l heads, cam.

 

A 98 block should have a 3.898 bore stock, the most GM recommends for a rebuild of the early blocks is a .005 hone. That brings you to 3.903.

Any 5.3 casting will work on a '98 block, its the 98 heads that won't work on later blocks. And the LS6 manifold will also work fine.

 

cool i guess that i will have to get center bolt vavle covers and the part that the coils bolt onto? thanks for the input!!!

 

Or you could use the opportunity to relocate the coils under the dash if the clean look tickles your pickle.

 

DO NOT FORGET ARP rod bolts!!!!

 

thanks no was already on the list of parts to get!
