Ok, I am in the process of building my first Hemi, and I am wanting to ask a few questions....first, what I have so far. 4.5 bore world block Ported Stage V heads Stock sheetmetal valve covers Mopar dual plane single 4bbl intake Dominator Rat Roaster intake mopar 9.5-1 4.5 stroker pistons My goal is 85 octane, 650+ horsepower 572. I am not wanting to debate the made in china thing, but I am wanting some guidance and ideas on what componenets to use and are compatiable. This all started with a killer deal on the on the block and heads. I have always wanted a hemi for my 68 charger so it begins. I am split between the H beam and I beam rods. I am thinking the K1 H beams or the RPM I beams, both have the 1.031 pins and 2.375 rod pins. I know the 2.20 journals are more common for the strokers but the I beams only come with the 2.375 journals. Next is the crank, Callies? K1? 440 source? Eagle? They all are about the same price, I am more concerned with quality. Cam selection is going to be mechanical roller. I thought about a flat tappet cam but with the changes in oil and ZDDP elimation made my decision to go roller. Hydraulic roller requires too much work to install. It was suggested to me to get a cam with about 240@.050, .570 lift and 116 lsa and .012-.015 lash. I am open to ideas or suggestions. Pushrod oiling? Do I need it? StageV rockers? stock? NWP? Indy? What will fit with stock sheetmetal valve covers? That is enough for now..Thanks Tim

go with the 2.2 journal crank. you will have to do less grinding on the block to get them to clear. with a bigger cam and springs and sheet metal valve covers the valve springs will probably rub on them, so you will have to clearance them with a hammer.
perception is 90% of reality

Yes, 85 octane, not everywhere I want to travel has premium. I have 100 low lead locally but not on the road

My elevation here in Utah is about 4-5000' above sea level, that is why the lower octane, at sea level the lowest I can get is 87 or 89, depending on where you are. Thanks for the input. Tim

.. best place to start -get the book by MoparRich (Rich Nedbal).

I couldn't agree more. Get Rich's book.
He posts here frequently too.
Also please DO NOT use Indy rockers. Even if you get them for free, delivered by the Victoria Secret ladies, and installed by Penelope Cruz. Just don't do it. Search this forum and DodgeCharger.com and you'll see why.
Rockers: consider Harland, Stage V, RAS. RAS site is http://rockerarms.com/rockerarms.com/Home.html

Contact Mopar Rich about a cam. He is a Comp dealer and certainly knows his Hemis and cams. I got mine from him.
Master, again and still

The octane is based on altitude. High in the rockies means low octane, Alaska is mostly sea level so 89 is the norm there.
I was thinking dechellies shafts, stageV rockers, KB stands. Rick Cassel has fair prices from what I have found on the net. If my budget allows it, I would love to run dual fast man efi on a stageV intake.... Tim

ok, well I pulled the block out of the box, new world block, and put it up on the stand. Found lots of casting flash in the upper water pump holes and one of the coolant passages at the rear of the block. I am expecting some but the passenger side water pump hole was amost closed off. Then I put a piston in the bore to see if it fit, it almost fell through. What should I have for bore clearnace? Block p# P5153862 and pistons are P4876327 and what rings should i get, mopar doesn't carry the recommended ones anymore. Tim
Piston with no rings, rod or crank should fall, you need to get some professional help me thinks .
