496″ Longram stroker engine (re)build pics:
– 440, +.030 oversize
– “Hawks Racing” 4.15″ stroker crank, H-Beam rods, 10.5:1cr Diamond-pistons.
– Edelbrock heads (84cc)
– CompCams XR274R-10 – Mechanical Solid Roller cam, 236/242 @.050 Duration, Lift .564/.570
The engine block has to be clearanced at various places so the rods didn’t hit the block…
Then after file gapping the piston-rings to proper sizes, further assembly was done.
A first a camshaft was chosen which I had laying around (Ultradyne mechanical cam, 255 @ .050″ w/ .582″ valvelift) but this was changed later for something milder that worked better with the LongRam intake manifolds.
Still 2 years later I decided to run a solid roller cam in the engine.
Further mockups and assembly…
After contemplating in which car I wanted to put this engine, I ended up deciding for my 1960 Chrysler NewYorker.
I have also installed a set of LongRam-intakes on the engine in the car, so I had to alter a couple of things on the engine before this would fit. Therefore I’ve changed the cam for a more milder hydraulic grind which works better with the longram intakes.
