All about My 1969 428 HO PONTIAC

I bought this engine /Transmission and Rear end and Traded my 400 Pontiac Engine / 350 Turbo Trans and 10 bolt rear end that came with the car + $1200.00 cash. I Paid Durham Engine $2800.00 To Do A Complete Rebuild in 2005. The Engine is a 1969 428 C.I. HO Block / 390 Factory HP / BLOCK CODE XF / BLOCK NUMBER 9792968 —-

 The 1969 Pontiac 428 HO engine, with engine code XF, was factory rated at 390 horsepower @ 5200 RPM and 465 lb-ft of torque @ 3400 RPM.

However, these ratings were underrated by GM for insurance and marketing reasons. Independent testing and real-world performance suggest that the true horsepower output was closer to 420–440 gross horsepower, especially considering the engine’s components and how it performed in period road tests.
