I wouldn't claim to be an expert, but forged internals will be more expensive than cast and if you go with a 347 stay away from the 5.400" rods and get the 5.315" rods. There's a lot to consider so try to get as much info as you can before you spend any money.

isnt there a 331? what one is the easiest and cheapest and most reliable?

a motor is only as reliable as the person who puts it together.

you want to make it last make sure its put together. on another forum i hang out on there is a guy with a 347 that has 70k on it so that sounds pretty reliable to me

CheapestAND most reliable is almost a contradiction of terms, but you should be able to do a 331 on a budget. With a 347 you'll have to notch the bottom of the cylinders so everything clears with the 3.400" stroke. Not that its a big deal really, but I'm pretty sure the 3.250" stroke of the 331 will clear on a stock block. A nodular iron crank and cast pistons would be cheaper than forged stuff, but won't be as robust. Should work okay in a daily driver though. One of the nice things about a stroker is that you can run a bigger cam without killing your cylinder pressure. Likewise, you can step up to bigger heads, etc. If I were keeping my sn95 I'd probably stroke it, but I've got a new GT so the old one is going up for sale soon. I could always use the proceeds to put a blower on the S197!
