Small known facts while on the subject of engines-a 100% factory stock Studebaker V-8 shortblock can take well over 30lbs in turbo boost all day long while revving up to 7 or higher. The stock Stude has forged internals and the beefiest block I've ever seen. Some people bore them out .140. The factroy rotating assembly with the most horsepower used to be the 301 Stude in Jim Lange's car, close to 1000 HP with lower 30's in boost pressure from twin turbos into a home-made intake and modded R series heads. A 100% stock rotating assembly. Cast rings. I don't know if it still holds the record or not. Buick engineers, when designing the turbo V-6 of great fame, copied alot of the 1948 Studebaker blueprints on head design and valve angles. On the Stude there are 7 bolts around each cylinder on the head. While engine has 2-bolt mains these are some BIG bolts. That has to be the cheapest engine to boost since no internal modifications are necessary. They have huge pushrods, solid-lifters, heavy shaft-mount rockers and timing gears. The only weak points on the thing are the tiny intake valves, which is an easy fix, and the short 1.4:1 rocker ratio which is a bit more difficult to change. The thing weighs in at 800lbs, almost 200lbs more than any iron big block. It was the first production small-block V-8 in the 1951 Champion. Small block, at that time, meaning the mains were external from the block. By original terminology definition the Big Chev is a small block and the new LS series are big blocks. For those who don't know, displacement has nothing to do with big or small block definition, it's purely based on the engine's construction. The Stude is a remarkable beast, and many Stude owners have 250k plus on the odometer on stock engines with no rebuilds. The oddest performance giant I've ever seen. I loved mine, shouldn't have sold it.
