Selling the 455 installed in my dads 69 GS. Previous owner, member here, purchased and installed it around... 2007 - 2008 if memory serves me right. Mileage on the engine was unknown at the time of purchase and has been driving ~2500 - 3000 miles since installation. Performed a compression test on the engine and all cylinders were 120-125 psi which is respectable for a 455. Oil pressure is right at 10psi at idle and ~35 psi cruising. The engine runs very well, doesn’t skip a beat and have no concerns about it. It is only coming out as I have rebuilt the factory 400 to bring the car back to numbers matching. Will be sold as a long block. There will be no carb, exhaust manifolds, distributor/wires, front accessories, oil pan etc. You will notice in the pictures it has 400 decals on the valve covers which was intended to keep it looking original. Engine will be out of the car on or before November 15th $750 is what it takes to own it. Shipping is on the buyer. Prefer local pick up, but can prep for shipping. Pictures will be added this evening. Not loading from mobile device.
