Stopped at a grocery store today,and a Pontiac LeMans pulled in beside me. Probably a 65-66 ,sporting the Sprint badge. I have heard about this engine and heard that there was this car in town,but was the first time I had seen it. Did a quick read up on it, 230 cid 2 versions of the eng. One with a 1 barrel carb,not sure of horse power,the 2nd with a 4 barrel carb,hotter cam and split exhat header would put out about 207 hp. Now the gears in my head got going about popping of of these engines into my 54 3100. So my question is, has anyone gone this route with the Sprint engine or, know of anyone who has?
