big block 366?

i have a 366 truck motor i'm putting in my 66 truck but i don't want just low end power but i understand it won't be an all out powerhouse can i stick a different crank and or rods when i rebuild it with some high dome pistins, cam, ignition system on it and get power out of it?
I don't know what crank is in it or rods or should i scrap the block is it even worth m

the truck rods are super strong, the crank should stand up to about 550 horses. but the block has got to go, its tall deck and small bore.. i would find a 427 tall deck block and a stroker crank but it all depends on what ammount of power you are looking to make, and how much money you want to spend.. a 572 cui crate motor will deliver LOADS of power and cost an arm and a leg, and a stock rebuild from PAW would be super cheap and make you arround 200 horses, so i guess the answer to this question, is like to so many others.... it depends.

When we get a 366 engine in we keep the crank,rods and the main caps. the rest is cast iron scrap. As far as I know there are no hi-perf pistons available for the 366, small bore and tall deck= no goodies. The crank is forged steel, same crank as 396-427 but balanced differently, the rods are usually the heavier duty 3/8 bolt rods, with a bolt change and a recon they are good for many horses, the main caps are kept around to install on two bolt blocks or to salvage bad four bolts.

i would propably find a used bare marine 502 block and install the crank and rods in it yieding a high winding 452 cui add a set of pro topline heads, they cost 1600 bucks with all hardware and outflows almost everything, install a 290 degree hydraulic roller (which the block is set up for) and you should be makeing 600 horses easy
