i cant remember the exact cam but its 23x 23x early comp grind not ideal for a FI motor but its always been fast and reliable . lots of ls motors breath heavy . do a leak down test and comp to be sure , it had a new spigot when the box was changed,i would put breather into catch can and see how it goes from there. most big cams smell rich
I'll do a compression test at the weekend and see how it goes from there, I don't have the leak down gauge set but if need be I'll borrow one and that should give a bit more info. Nice new catch can arrived today so I'll get it fitted after compression test is all done, that is unless I have a holed piston.

Doesnt sound too big unless LSA is very tight.For a low boost PD style blower stretching the cam a little isnt always a bad thing.
Compression test was when the engine was cold too, hands an hot manifolds don't mix. Here is a pic of the plugs from right to left, first on the right is drivers side front cylinder and opposite on the other side. Front plugs are slightly oily due to oil coming out of the breather pipe that goes into the inlet.
