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.

Dunno, Im not doubting you but I got that info stright from Rick91gt on here
