We have been doing a lot lately for 100 point restoration crowd, today we are all about the guys who like to go fast with little concern for factory specs!
One of my favorite types of Posts are the ones about what you guys and gals are working on in your garages. This time I have a very unique update on a project that involves a bunch of us and is truly and International Project Car. Let’s start at the beginning. Marty Burke had a black (original maroon) Talladega without and engine and transmission. I was looking for a Talladega to build into a wild resto-mod street car. I purchased the car from Marty and bought some coil overs, power rack and pinion and other parts for my project but never got started on it due to others that were taking too long. I then sold the car and parts to Team Member Kjell Rygge in Norway. His plan for the car was similar to mine but even more ambitious. He wanted to do a car more like that of Rick Stanton. He and Rick got together and Rick is now building one wild Boss 429 engine for Kjell’s Talladega. The following photos and information were provided by Rick.
Rick says Kjell wants all real vintage Nascar Boss 429 pieces if possible. Rick is furnishing: Nascar Block, Nascar Rods, Can Am 494 Crank that he is stroking to 4.25 stroke as well as
a complete Nascar Dry Sump System, and Nascar Spyder Intake. He just last week ordered the Custom Pistons for it. The Nascar Block is .400 thick so he is boring it .200 over. It will be 4.560; the engine size will be 555 cu.in. and should should easily make 750 HP plus.
To explain what these additional pictures are:
On the Dry Sump Dampener you can see where the Gilmer Drive Belt runs off of the back of the Dampener to drive the pulley that will be on the front shaft of the Dry Sump Pan which is 2 pieces bolted together, the pans can be in all Aluminum or all Magnesium.
Picture Boss 429 Head shows after the Heads were Ported, Stainless Steel Intake Valve size is 2.400 that Flow 425 cfm @.650 lift @ 28″, the Stainless Steel Exhaust Valve size is 1.94 that Flow 278 cfm @ .650 Lift @ 28″.
These heads flow enough air to support 873.8 HP.
The Nascar Spyder Intake was ported and sandblasted and now flows enough Air ( cfm) to support the heads. As a reference, the stock Boss 429 heads only flow 342.7 cfm @ .650 lift on the Intake and the Exhaust flow 249 cfm @ .650 lift. The picture (Powder Coated Semi Gloss Smooth) is the Dry Sump Belt Cover that bolts to the front of the Dry Sump Pan to protect the Belt and Pulley, Rick had 4 of these made as they are impossible to find.
A little info on how the Dry Sump works:
There is a gear on the back of the Dampener that turns the pulley on the front of the Dry Sump pan (see Dry Sump Pan picture).
There are two Scavenge oil pickups in the pan, one in the front and one in back, the Scavenge Pump in the front of the pan draws the oil out of the pan and pumps it into the Dry Sump tank, the tank is usually about 5 gallons of oil.
The Oil in the Dry Sump tank has a series of baffles (plates with holes in them to de-aerate the oil), the oil is sucked out of the bottom of the Dry Sump tank by the Nascar Oil Pump mounted in the normal place where a wet sump 429 oil pump is mounted, then the oil flows thru an Oil Filter and a Oil Cooler then back to the Engine to pressurize it.
Normal Dry Sump systems have 100 PSI of pressure at 7,000 rpm’s controlled by a bypass spring installed into the Nascar Oil Pump.
This Dry Sump System is referred to as a Three Stage System, Two Scavenge and One Pressure, today’s Nascar Dry Sump Systems are usually 5 stages, four Scavenge and one Pressure.
