I'm throughing this one out to all who have done this swap or to anyone that just knows the facts. Does the 261 fit right in the bay of a '53 1/2 ton? I'm running a 216 at the moment, but would LOVE to squeeze some horses out of a bigger 6-banger. And if I find that this in fact an easy operation, then I going balls-out!! I'll be on the hunt for the right 261!! I've been through the V-8 speeches, brothers, but I really want to stay with a nice, big and healthy 6-er.To stay as close to OG as possible. Through my recent searches I found a place that will rebuild any size GM engine for you,(
www.precisionengine.com )Since I'm more the Body/Paint man,this is right up my alley. Only if this is do-able. I'll around if anyone wants send me any kind of info. ..Check you guys later... lazy
