Re: 1979 351 Windsor: Worth Keeping??
The 79 block, as with all 351w blocks, is strong enough to handle 600+ hp. That is still more than the average enthusiast can dream about.
I'd pull it and either keep it for a project if you have the room or sell it separate from the car.
My little 65' Stang street car:
Dart 428W NA, 4 Spd, 4:33, on pump gas pushing 3550lbs.
