This project started back in 2013 with the start being a 240 head done by Jerry Arnold. He worked his magic on porting and put in larger valves and 1.6 roller rockers. The head was still in the box until last week. The block is now out for a thirty overbore, new cam bearings . The crankshaft has the counterweights shaved off. I hope to spin it in the 5000-5500 range This will be balanced once the rods and pistons get sorted out. I mentioned the procharger in the header and hoping to run 8pounds boost. The idea with this project is for 90% use on the street, 9% autocross and once a yr to the dragstrip at Brainerd ,MN with MSRA. Hell maybe do the ice drags in Merrill WI this coming Feb.
My questions to you learned forced induction wizards are: what rods and pistons make sense? I've seen the speedpro and silvolite piston along with the molnar , compstar and LS rods, but nothing points to what 's the better way. What numbers for the cam? Again all over the place .
It's these decisions(for me, not having the knowledge and experience) that are the hard part. Doing the actual physical part is the easy stuff.
