not much about it realy scat crank PEP rods I beam rods 6800 and a icon pistons i made up stroker kits with parts i like to used . that is base off of past history with who i deal with . 4.500 crank drops right in the milodon road race pan fits nicely the windage tray may need to be trimed abit and use the mildon tray kit .most time making things fit was dealing with the dip stick guide tube that bolts on the main cap need some fab work to make sure it not bending the dip stick and not reading oil or hitting the counter weights on the crank . roller cam is the only way to go . my own numbers that Erson cams custome grind . Erson roller cam all cores it this time are 4/7 swap for the pontiac built many with and with out the 4/7 swap lower HP and Tq under 700hp and offer more then hp the fire order cuts down on crank flexs helps the engine run cooler .HP and TQ numbers you may not see the gain but still nice to get any ways the custom core cam and custom grind is not any more added to cost . if you go roller you will have to cut out baffle out of valley cover as it hits the roller cam lifter bodys and you will have to reroute your PCV to valve cover .it can not stay in valley pan if the baffler is cut out for the roller lifters
