All kinds of problems

Overheating, detonation and such I would imagine.

here are my symptoms....

over heating, loosing coolant, white smoke, blowing head gaskets within 10 min of installing new ones... predetonation (im guessing), no oil pressure, and not full power

If you have the means, a crate motor will surely slove your problem with the least hassle. Call Monday and you be installing it next weekend.

or

Block or heads? Tear the block and heads down and have them magafuxed. If good, hone the bores, deck the tops, wash the block, replace the cam bearings and freeze plugs. new pistons, rings, bearings and gaskets.

You definitely have a cracked block. Sorry bud. But if you are losing coolant, you have no oil pressure and you're overheating, even if you didn't have a cracked block right now, go start it and run it for about 15 min and you will. Go get a crate motor.

I would still say take it apart and see right where the problem is, but in the end. I still see yourself going for a new motor.

You need to find the prob before u run of dropping cash on a crate motor...could be something simple.
I knew a guy that tightened his arp head studs in way tight (suppose to be hand tight) and on the lower row where the go down into the coolant passages he cracked the block.

You have no clue what it is right now, I'd calm down...dig into it...and find that gremlin.

Good luck bro
Chris

Just in case you go the crate engine route, check out these engines,

www.gefracing.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=G&Category_Code=50ENG

For under $3000 and free shipping, you have a new engine.

The timing cover and water pump is our type. Put on your old oil pan, your brackets, intake and a pilot bearing and drop it in.

Break up your old engine and sell off the good parts on ebay.

Just look for anything out of the ordinary, cracks in the cylinder, cracks around the middle of the block on the outside, where oil and coolant galleys are, hole. Maybe do a leak down test and see if you hear anything.
