Lets say "theoretically" I have an '89 Chevy truck, and the TBI 350 in it spun a rod bearing today and it's now got a very bad knock in the bottom end. Well, I just happen to have this nice 351w sitting around, and as it turns out, there are SBF to Chevy bell housing adapter plates available, and adapter plates available to mount the Chevy TBI setup on a number of intake configurations... and by my measurements, if I put a set of frame mounts on the truck for a 4.3 V6, and use 80's crown vic rubber mounts on the engine, it would be very close to bolting in.... Why wouldn't the Chevy throttle body fuel injection run the 351w? I drove the truck to work today and it spun a bearing on the way there. To it's credit, it made it 10 more miles to work with the rod knocking bad, and then made it 35 miles home this afternoon, and it still hasn't spit the rod out. I've had this idea of dropping a 351 in it since the day I got it, and now I've got a reason to try it..
