I have an 454 block with casting #361959 2 bolt main where its bored 0.040 over, 0.020 main bearing, 0.030 con bearing.
I need a complete combination parts that can increase my horse power to around 500 hp if possible and can be used as daily drive street performance and with air condition for my 69 Camaro.
My trans is th400 3 speed automatic.

I agree with above--if your keeping stock appearing( heads date coded ??) See what they are flowing, if they need work . Than email a reputable camshaft company with the info and they can recommend a package. Don't overlook the strength in the rotating assembly. Food for thought ,but 496 assemblies seem to be pretty popular if you need to strengthen and go  the route of upgrading. Number one rule is keep everything a package. No weak links. Do your homework and research what you have. Many good websites identifying cast numbers. try: outintheshop.com

Buy a Scat 496 rotating assembly .  All you have to do then is make 1 hp/cu inch, a piece of cake.
Use a hydraulic roller cam about 220/230 @.050" with about .550" lift.  You can use the factory long-slot rocker arms and keep the stock valve covers.
Look for oval port heads with a casting # ending in 781 or 049.  Have these rebuilt or better yet buy new edelbrock heads.
Compression should be ~9.5-1 for cast iron and 10-1 for aluminum.
You will have a nice idle and tons of torque. Shift at 5500 to 5800 rpm and have fun without breaking parts.   Smiley

what he said...

Just watch the compression,  if you want to stay pump gas friendly..   I went way over kill in the 90's with my vette,  its about 14 to 1 compression.   was not a big deal back then as 110 leaded was $2.99 a gallon... its not $7.99 and well i still only goes about 140 miles on a tank lol...    Its fun as poop though Wink 

If i had it to do all over again that what i would do with a 454,  496 stroker 10-11 compression  nasty cam ( im a cam guy) good clutch and beat it ever day...    Only problem i have is i like RPMS,  and it cost to turn a big motor,  The msd in the vette is set at 8K  :-)   love it  threw headers and factory sides,  although my head hurts when i get home...
