Caprimaniac Rus I have a Daany bee going on my 498 motor.
Here's the thing You have no cover to keep it clean and debry getting in the teeth. It doesn't make the most HP. Line up and correct camshaft end play are very tight. A street car may not be the best for this in the long run. Price for it is high, about $600-800.00 dollars a good Cloyes roller timing set about $225.00 and 100K life with oiling directed to the chain.
Good things, COOL AS HELL, adjustments made in 10 minutes. Vibrations in the motor reduced. Neat sound when running. Have been told the belt will last about 50K miles.
The other thing is how big and strong are the valve springs, lift total on the camshaft will all come into play with belt life on this setup. NO
oil on the belt. Not even sure if a belt dressing is OK. We will see. Ps carry a spare belt and tools to repair on the side of the road. Should be able to slide in without pulling the front of the motor apart. Looks tight but doable. Rick L. Ps make sure it fits the block.
Oil pan sealing is important too. May go from a gasket to RTV. Watch back pressure in the motor, may want to add a low pressure vacuum system with a 2-4 psi pull. Good luck Rick L.
