I am not familiar with the first two cars but I had 3 VWs over the years. The first one that I bought had a cracked crankcase. I got an estimate for repair which was expensive. I had the money but chose to repair it myself. I bought the new crankcase and main, rod and camshaft bearings. With the rest of the money I saved on labor of having it done, I bought high performance parts: a Crane Fireball Camshaft, headers, a Holley 2 bbl carb, a high ignition system and new intake manifolf along with 88mm bored out cyls. and pistons. It was a major thrill to crank it over for the first time and have it fire up. It was a screamer. I used to take the Pennsylvania Turnpike from US Highway 1 out to Norristown. At that time we all had CB's in our cars and I always got people calling me to ask if I had a Porsche engine in the car....Frankie
