Quote: If you are going to make over 600HP with a stock block, You should ( at least )half fill it - and go aftermarket main caps or a girdle. No question IMO on that one. You should also make sure the block sonic tests real good.
When you say aftermarket main caps, are you referring to the 4 bolt ones? or are there 2 bolts that are available to add strength? I always thought adding 4 bolt caps to a stock block weakened it more than anything
Never been a big fan of girdles...Have always felt that most of the small block designs don't seem like they would do much...but thats just my opinion
Not a girdle fan ether. Went with Milodon 4 blt main set up on mine.
IMO best caps for the small block that going to see street duty. Ductile iron stong and same expansion rate as the block. Matt
Matt, are you running those caps in your Indy motor? Or is that motor an R3????
