I have a 72 sbc 350 now. There is a brand new vortec long block for sell close to me for 700. I'm thinking of getting that and selling mine. I'd like fuel injection for offroading (it's in a jeep), but I don't want to pay for an aftermarket unit. So it's cheapeset to buy a used motor with the fuel injection already on there, but if I have to change it anyway because of the increased power, then I might as well get that good deal on the brand new vortec motor.

Thanks
