For Sale: 1965 Buick Riviera 425 Gran Sport Engine and matching BS Code SP400


Recommended Posts

I'm doing an LS3 swap into my 65 so have decided to sell the engine and trans.

It's not a numbers matching car otherwise I wouldn't do this.


Genuine 1965 Riviera Factory LX Code 425 Gran Sport Dual Quad nailhead engine complete.
Previous owner painted the engine red but it is a 1965 engine which was green.

New AC compressor, New Alternator , New Water Pump. Carburetors were plated and overhauled

The engine has blow by so will need new rings at least.

Good oil pressure and no excessive oil consumption though. (20psi at idle and 30 running, uses 1 quart per 1000 miles)

Matching Gran Sport BS Code SP400 Transmission with new torque converter included.

(professionally rebuilt 11K miles ago)

For US customers, currently AU$1 = USD 67c so take 67% of the price shown to get the US$ equivalent, shipping is no problem and I've been told to allow about AU$1500 (approx US$1000) + cost of a custom-made crate.

Contact me for more information.
