    I started tearing down the block, am very encouraged, everything inside is spotless, and all the used parts look new. Bore is even very nice. The gift of changing oil and maintaining is what you see.

    Ha, no all NA, BUTTTT....I did order heads today. I have literally spent a hundred hours researching this, and though there are not the biggest or baddest, they will be an excellent fit for this build.

    At this point, I will have a newly machined block that I can take home and do some of the above mentioned prep. Yes I chase all threaded holes on the block, which leaves me with the last block mod. On the intake side of the deck, I will cut a chamfer in the cylinder to promote low lift flow...

    After much checking, and inspecting, I have selected a local shop to do the machine work. Dick the head guy is an ol' coggie like me, and has let me in the shop to see his equipment. He will line hone the block, deck the block, bore it out and finish torque plate hone with a Sunnen hone, like...

    My block is a two bolt main, so I bought Arp studs, which have a higher torque value. I have kicked around the thought of installing the splayed mains but haven't pulled the trigger .....yet. Seals and gaskets are Felpro. When I get the block back, I will also radius the bottom of each bore...

    I like "pretty" engines, so i bought brass freeze plugs. I will deburr the engine on the outside, and perform a number free hp upgrades that I will document, on the inside. Some may be new news, and some old.

    Part of the equation also are the harmonic balancer, and the flex plate. Both these pieces will do the job, and are SFI approved. These have been balanced like the rest. Flex place mfg. by Scat.

    It's been tested, the stock BB can handle 600hp, but the weak links are the hypereutectic stock pistons and the rods, more specific the bolts. The Wiseco pistons will handle over 800hp, so I purchased new rods to match the pistons. Only thing I did to the rods is upgrade to ARP 2000 bolts, then...

    To build a thermally efficient motor, you need some compression, and I have settled on 10.5 target. Pistons have a 20cc dome, a .010 taller compression height, and are forged from 2618 aluminum alloy, which will require .004 piston to bore clearance. I chose them because the 2618 material can...

    To build a 489, requires a 4.25 stroke, with a 4.280 bore, so pretty square. Crank is an Eagle cast unit which is plenty good for the power I need. Only thing I did is had it micro polished, and race balanced to 2/10 gram. Pistons are Wiseco, I have used them before and these are fully machined...

    Block is Mark IV virgin block I have been running. This engine has been excellent, solid, dependable, easy to service, good torque estimate around 400 hp at present. I have purchased quality parts to make this a 489. My goal is, obviously more of everything, torque, power, easy to maintain...

    On my 6.2, when it is cold, and is have steady peddle pressure, the engine does rev up some, then shifts and etc. It is not a big problem in my case, and I think it is a governor adjustment...or not. Never ran away.

    Pull #1 spark plug out, have someone turn the motor with you plugging the spark plug hole with your thump, on the outside, no finger in the hole. when air starts to push past your thumb, you are on the compression stroke, watch your balancer, and stop when you see marks. If it is greasy, clean...
