I've only ever heard of them in the 377" size but it certainly is possible Penske ran something different.

My understanding was that Bill also thought it was a 377ci engine; but upon rebuilding it the crank stroke was determined to be 3.622 not 3.75. The bore was 4 inches .

Here's an excerpt from the Grandsport book which quotes Bill. Perhaps they used both displacements in different cars. I know he wasn't pleased later on when he had to install a big block in the car. He loved the SBC.

&quot;Corvette Grand Sport&quot; book by Friedman and Paddok on page 135 a comment by Bill Scott, one of Roger Penske's most trusted mechanics, that stated, &quot;I ended up building an engine, it was a 364 ci engine, not a 377 ci as many people believe.&quot; That statement was in reference to the 005 Grand Sport being prepared for the 1965 Sebring race. The famous 377 ci small block Grand Sport engine had a 4&quot; bore and supposedly a 3.75&quot; stroke which gave it 377 ci. According to Bill Scott's statement the correct engine size was not 377 ci but had the same bore as the LS2 engine (4.00&quot and stroke (3.622&quot which results in 364 ci.&quot;

----I may be wrong, Jon, but I believe those Webers are 58s. They are almost big enough to stick your whole hand down into if it wasn't for the butterflies. They may be the largest Webers ever??? And,,,Theres a good shot of the brake booster mounted sideways with the bell-crank actuator......Bill S
