Comp ratio and PR length question Hi guys im new around here so just want to say hey and see if any of you knowledgeable folk can help me out before i purchase some parts.
First off what im doing to my ls1 346 stock bottom end.
224/228 .581 .588 112 + 4 XE-R
Morel tie-bar lifters
TFS215 milled to 60cc
YT roller rockers 1.7
.052" GM ls2 gaskets (4" bore)
What i'd like to know is what comp ratio (static and dynamic) would this set up give me, also what length push rods would be right on this set up?
Any help appreciated.
Cheers Nick

Those lifters have a narrow range of preload (0.030 to 0.050 inches), so you may need to order a custom length push rod. (I like the Manton push rods). Here is one measurement technique: https://ls1tech.com/forums/7957678-post2.html
