First fire-up of the 440" W2 Stroker small block

Hollis Page at www.HPEngines.net did the machining and assembly.

Probably not going to dyno it since the W2 headers will be hand built in the car. The puny 1 5/8 LA flange headers would handicap it. I'll probably chassis dyno it and for sure I will 1/4 mile test it.

The combo is basically the same high torque Streetwize Recipie we used back in May on my buddy Nat's 442" AMC motor with ported edelbrock heads and 2.05 valves.!That one used a hydraulic roller that was 238/244 @ .050 and 109 centers in at 105. it made 543hp and 547 lb/ft peaking at 5800 rpm. The dyno sheets are on moparts in the Jeep section.

This is the same basic configuration but the Mopar has a bit better flowing W2 head with 2.08 valves and a bit more aggressive Solid Roller Bullet 251/259 on the same 109 spread in at 105. The solid is about 10-12 degrees bigger at .200 than the Hydraulic so we conservatively expect it to pull 570 lb/ft and around 580HP at a bit higher 6200 RPM.

Not sure the thermal barrier coatings will pick up power noticably but it sure won't hurt it.
