stock block vs. aftermarket

well im looking to get a 88 notch which i plan to do a 5.0 conversion on. i bought a stock block off some dude for 50 bucks. it has some rust inside the cylinder wall from sitting outside so it needs to be bored to be useable. i want to make some serious power but i dont want to blow the block apart. should i go wit a 306 or a 347 wit the stock block? or should i just not bother and wait and get an aftermarket block? i dont really plan on running the car at the track but i dont want to blow the motor either.

You really don't need the Man O war, or even a dart.
I've seen cars that make over 1500 to the wheels with an R302, and others over 1000rwhp with A4's.

yeah but after the machine work on the R302 {probably the a4 but i dont know much about it} they end up being roughly the same price

I had heard the same thing here.
So i asked my buddy Dwayne who owns a mustang shop, and he said that any work he has done to the R he also has done to the Dart.
Not my words, but out of the mouth of a seasoned veteran.
