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 with air condition and power steering for my 69 Camaro. My trans is th400 3 speed automatic.

There are literally 5 million combinations of parts that'll let you hit 500 hp in a big block. Get a nice hydraulic roller cam, ported stock iron heads or ANY aftermarket aluminum heads. A single plan intake manifold, an an 850+ CFM carb. Pretty much any long tubes. Keep compression up to a minimum of 9.5:1. You'll hit 500 HP with your eyes closed.

If you live anywhere near southwestern Ohio, I'll sell you a 525 HP big block thats comes COMPLETE with everything, including MSD Box, for $2500.

 

9-1 454, forged pistons, hydraulic flat tappet Lunati VooDoo cam. Get some -049 or -781 cast iron oval ports and have them cut for 2.25/1.88 valves or 2.19/1.88 valves. RPM or RPM Air Gap intake...might check to see about hood clearance on your Camaro. If you don't have the crank and rods, it may be a wash to buy some versus buying a 496 rotating assembly. But, don't be afraid of a cast crank they are fine to upwards of 700 HP. Stock rods will live with good bolts, the thumb print 'truck' rods use the 3/8" bolts....they seem to be s strong as the dimple rods without 7/16" bolts.

Otherwise a 270 ish cam, will work brakes and steering, sounds like the old 350-360 HP 396 or LS5 454...
