I am planning on running 2.5 intercooler piping. I think that should be sufficient, fill me in. You guys are all great for the ltx community! Thanks, it really does help a lot!Quote:

My 355 build was 8.5:1 but the roots blower negated any low end doginess. There was really no such thing as "off boost", it was either idling or balls out so I can't help you in that aspect. What size combustion chambers/heads are you running? Has the block been decked? Also, the 5140 rods are no stronger than stock ones, so look into a 4130 rod.
I just now saw this. That cam would work pretty well imo.
I'm 8.5:1, its not horrible out of boost but I'm an auto and a 383. I do plan on bumping it to 9.5:1 this winter, e85 will like it better I bet.
2.5 or 3 inch cold side piping? Personal preference or actual gains to be had?
Size it off the smallest point of the cold side, whether it be compressor outlet, IC ports, MAF, or TB.Quote:

At what rpm/hp/boost would the 2 bolt mains start to be a weak point? They will have studs. And for those that have done the 4 bolt splayed mains, how much did that end up costing you? Thanks for all the help. I've been gathering parts slowly.
The 4-bolt conversion is worth it IMO, as you always want more power and it's pretty easy to increase boost with a turbo. Might as well have the 4 bolt caps in there ;)
