Time Capsule

One of my clients brought this Pontiac motor, it's an old fuel altered motor from Frank Pedregon's fuel coupe, before he switched to Chrysler Hemis. This thing was parked under a bench in the mid 1960's and is a real time capsule to what they were doing at that time to make 1200-1500 horsepower. It's incredibly crude!

This motor started as a 370 block and crank. The crank is a welded up stroker and the block is decked about 1/2" to make about 450 inches and 14.0:1 compression. The rods appear to be factory Pontiac forged rods that were boxed by welding plates along the sides of them. The heads are highly ported  and you can see most of the valve from the intake port. It's almost a straight shot. The cam is an old Isky solid roller with cam lobes that are almost square.

There was a flywheel included, it looks like it was part of a multi disc setup. There's friction material on the actual flywheel so I'm guessing there was sintered metal plates floating in between.

Not sure what will happen with this one right now, but very cool and a window into old technology.

Look at those cam lobes, almost flat. Looks like 359 degrees of duration!

This oil pan was beat with a ball peen hammer to clear the stroker crank.

Here's a view of the lower end, you can clearly see the welded material added to the crank and the boxed rods.

Here's the flywheel, it weighs a ton.

Part of the solid roller valvetrain. Isky circa 1962? They were still in Inglewood at any rate. Cool!
