dr_hunt Posted September 19, 2006 Share Posted September 19, 2006 I don't think I've read anything bad about these. What's wrong with them? LS1's seem to have an oiling problem at high rpm from what I've seen and read. I think Mikelly knows quite abit about this issue. Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted September 19, 2006 Share Posted September 19, 2006 I don't know if I would call LS1/6's junk, but GM did make several changes to the LS1 oiling system over the years that seems to have addressed some issues. The 98-99's were different than the 2000's and on, and the LS2's are different yet. The LS2 blocks are suppose to be stronger too. As a point in reference, for the LS7 GM went to a dry sump.

Well, the LS7 is DEFINITELY out of my price range... don't know about the LS2. Will a dry sump oiling system cure the older LS1/LS6 lubrication woes... and/or some machining of oil passages? The more I learn, the less I know... oh well. Quote Link to comment Share on other sites More sharing options...

MAXIMUS Posted September 21, 2006 Share Posted September 21, 2006 There's no replacement for displacement. Keep it simple. Go for the bigger cubes if ya wanna go faster! Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted September 21, 2006 Share Posted September 21, 2006 There's no replacement for displacement.Keep it simple. Go for the bigger cubes if ya wanna go faster! Some say 383-396 stroker... others say 434-454 stroker... still others say $crew the SB and go BB600+ stroker. I have to say... those big cubes are tempting. I know I can make a very easy-to-drive kick A$$ motor with more cubes. Making big horsepower with a smaller motor makes streetability questionable. However, the weight and expense of a BB are issues. Also, reliability comes into the question. Decisions, decisions, decisions... Quote Link to comment Share on other sites More sharing options...

LS1 240Z Posted September 21, 2006 Share Posted September 21, 2006 i say LS1/6s suck becuase of their small bore... you can buy ported 243 (LS6 ZO6 heads) for about $1200, they flow around 300 CFM at .600 lift lets look at the LQ4/9 LS2/7 and L92.. you can buy 2 brand new L92 heads (you need a 4.00 bore) from GM for $800.. stock out of the box they flow 330 CFM.. it essentaly made the LS1/6 obsolete. only motor that dosent have the oiling problems is really the LS7 with its dry sump.. vette oil pans are a remody also.. what happens is that oil travels away from the pickup tube and it can starve for oil during high rpm/high skidpad #s (ie drifting and road racing) the simple solution to this problem is to ad an extra quart of oil.. seems to solve the problem Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted September 21, 2006 Share Posted September 21, 2006 What about converting LS1 to dry sump? i say LS1/6s suck becuase of their small bore... you can buy ported 243 (LS6 ZO6 heads) for about $1200' date=' they flow around 300 CFM at .600 lift lets look at the LQ4/9 LS2/7 and L92.. you can buy 2 brand new L92 heads (you need a 4.00 bore) from GM for $800.. stock out of the box they flow 330 CFM.. it essentaly made the LS1/6 obsolete. only motor that dosent have the oiling problems is really the LS7 with its dry sump.. vette oil pans are a remody also.. what happens is that oil travels away from the pickup tube and it can starve for oil during high rpm/high skidpad #s (ie drifting and road racing) the simple solution to this problem is to ad an extra quart of oil.. seems to solve the problem[/quote'] Quote Link to comment Share on other sites More sharing options...
