5.7 Vortec Swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I would like to know if it is worth installing a 1997 350 Vortec into my 71 Chevy Truck? I have a new 350 transmission and was wondering if the new vortec would bolt up to it? The Vortec engine is complete with flex plate.

1. Are the motor mounts going to bolt right in?
2. Is my th350 transmission going to bolt up to the vortec with its flex plate?
3. Should I try to use all the fuel injection stuff or just go with an intake and carb?
4. Should I try to get the 4 speed transmission also? If so what will it take to use it in my 71 Chevy? ie. wiring, computer, sensors, linkage?

Any and all help would be appreciated.
Thanks in advance.

Please help.
