Just a stock rebuild. 1000 bux or less hopefully. just tryin to get it cleaned up and throw in some new bearings and stuff but i need to find torque specs for the mains and rods and heads and whatever else that i would generally have some probs with.

350, 400, 426 and 455's are all the same block size and considered big blocks.....
$1000 is going to be tough but do-able if you don't need pistons or rods.

500 for all the bearings 150 for complete gasket set 150 for everybolt on the motor 300 for machine work 75 piston rings and valve seals
I came out at about 1200 bux. It did take a lot of lookin around though i had to take it to a machine shop 30 miles away

I had a good friend in highschool with a 400 Pontiac in a 1972 Ventura.
He beat on that thing for 4 years on a nightly basis and it always ran like a top. He even used it for a DD for a couple of years.
It was a mild build and ran high 13's, which was strong in the early 1990's...
I love those motors..

look on http://www.thirdgen.org also. Lotsa folks like to build these for third generation f bodies. I seen 400sb blocks/heads/internals in the for sale column regularly. There was a guy in Nashville was looking to clear one out, I almost went for it for my 89 gta, still considering options though. Think he was letting the block (which had been cleaned, decked, honed and magnafluxed) for like 300-400 and the original stock internals thrown in for free. If you keep your eyes open for a while, you'll catch something eventually. If you are in a hurry, well then...$$$

Rob97 is right,

Is the best and biggest Pontiac site on the web.
Depending on your current motor and if you can do the build yourself, $1K isn't out of the question.
