SOURCE: 350 chevy small block

Aftermarket intake, camshaft and either a good set of heads or port/polish what you have. If you go with a cam, go with more adv. duration and duration and .050. I like running a .525 lift, .230 dur. @ .050 and .292 advertised duration. Get a good set of springs and valves. This cam should get your redline around 6200. If you're using this engine on the street, I prefer the Performer RPM with a 1" spacer. This provides plenty of velocity to the heads. If you can find a set of camel hump heads, casting number 041 you'll love those or have your heads ported. I'd run a Edlebrock 1407 carb. with this set up if you're using it on the street. If you're using this engine for strip duty as well, use a single plane intake like a Victor Jr. Professional Products have a nice selection of single plane intakes for a very low price. I've bought one myself and really liked it.

SOURCE: i need to replace the rear main seal on my 95

Yes, either pull the trans or pull the engine. No way to get in there with out having one of the two out!
FYI it's very rare for a rear main on that engine to leak, Most all of the time it's the oil pan gasket or coming from higher up like a valve cover or the intake gaskets!

SOURCE: is the rear main seal on a 1999 gmc yukon a 1

its a one piece. should be the metal one with the rubber inside seal. of corse you gatta pull the tranny but its a good time to change fluids and maybe slap a new torque converter in. changing the rear main is pretty easy after the tranny is out.

350 chev engine number 10054727. What year and horse power? Thank you

That is a '89 & up model, I believe it is a 2-bolt. HP is not determined by this number It could be from about 165 to 295. You can pump it up, but don't go too far if it is a 2-bolt.

I have a chevy 350 4 bolt main with suffix code ce4329 can anyone tell. Me what year, and horespower this engine came with.

I went google and typed in-- 350 chev engine suffix number ce 4329 and found a page chev-camero.com>chevy-camaro
listed is a ceu--1980--350--190 hp
these 4 bolt main blocks were sold here as bedford truck engines ( 5 ton trucks) as they had a slightly longer stroke which gave a better torque rating for heavy loads
They were popular as street engines, because they gave better power bands that could only be got by regrinding the crank to gain more cubic inches( longer stroke ) a 350 engine and adding special head gaskets for the piston protrusion above the block
Along with good cams , the 4 bolt main negated the need for expensive main modification to handle the extra power
anyway go to that site and navigate around and you may find the information you want

The number on this Chevy engine is K0831PHC and below that the number is CJ 710556. Can you help identify the year and vehicle type this was used in?

K is for the factory in St Cathernines Ontario
0831 is the last day of August
and PHC COULD be for a 1988 350 truck engine.
The CJ710556 may be the Chevy division and the casting number for the block, or the serial number.

2003 dodge Intrepid 2.7l oil leak above rear main seal after running 20 minutes

rear main seal usually only leaks when the car is running. though oil will slowy drip off afterwards. now the best way to tell is to remove the heat sheild that covers the flywheel and look at it and at the flywheel . is the oil only on the engine side of the cover or is it inside the cover and on the fly wheel. the rear main seal will leak into the bellhousing and on the fly wheel the oil pan gasket will leak on the front of the heat sheild.

Settong the timing on a 350 small block.

On that set up the computer mainly sets your timing. It reads the timing off of the crank sensor, cam sensor, it tells the injectors and coil packs what to do.
