stock 440 rebuild - 03/17/13 06:51 AM
Spent the day helping assemble a 0.030" over 440 for a friend today. First time in almost 10 years to put a stock engine with no modifications together.
The crank was only polished, so all stock sized bearings, stock replacement cam, stock replacement pistons (I'll have to get more details on those tomorrow), stock 906 heads, cut 0.010". The heads were 89cc. Tomorrow, we will degree the cam, and see how far below the deck the pistons are.
I will have to get the name of the cam and timing set. The guy just got all the parts from the machine shop. Timing chain has no way to adjust the timing, uses a slot where the cam pin goes? I guess if it is way off, we could drill a hole 180 from the slot and then use a degree bushing?
Used the Superperformance rear main seal kit, and it went in pretty easy. The blue side seals seem a bit stiffer than the orange side seals I had in the 440 source rear main kit (comparison of silicon side seals, fwiw?)
The guy was really impressed with how easy the tapered piston ring compressor is to use.
