402 LS2 worth the extra $ over 383 LS1?

[2001WS6Vert]

I won't respond after this...but. Why would GM make the change to the higher location in later designs? And why are people who are running 7 sec. 1/4s budget builds choosing LS2/3 blocks instead of LS1's? Is there a 7 sec. LS1? So, I disagree about your statement that, "it's always preferable to secure the stud at a lower location".

Because the liners in the bores on an LS1/6 are shit.

Basically the LS2+ platform is a better block design.

Its not uncommon on some engines where the studs screw into the top deck, to drill on through and tap the lower regions to create a long stud setup on some smaller high powered engines.

And some other engines like Subarus are already threaded at the base of the block for its fasteners.

its not just LS2/Ls3 that run the shorter studs.

04+ plus blocks run the shorter studs, this includes the iron blocks as well

Its maybe due to necessity with the larger bore sizes. Maybe just not room for a stud or bolt to go right to the bottom of the block. Or probably just cheaper, and the stock engine head gasket seals fine anyway.

or the fact that gm made it simpler and cheaper to have bolts produced that are all the same lenght.
