Default Double Roller Timing Chain Guys Please Read

Doing A balancer job on a 2001
Going to do Melling Hp Oil Pump - its the same as M295 but with
10% more pressure(and parkarkized gears, etc)

I have both chain sets in front of me.. Single & DOuble.

How much of a pain in the *** to use the Double Roller??
IT comes with the 2 spacer pieces, and the Crank Drive piece
is Shorter than the single (compared to each other.)

Car is just a driver.. No track BTW

You'll have to clearence the timing cover and grind down the oil pump mounting bolts, unless new pump came with new ones. Honestly if its just a daily I wouldn't mass with it, just get the ls2 chain.

The timing chain damper will provide more timing chain safety than a double. Getting the wrong harmonic damper can break either.

This block does NOT have the holes drilled for the LS2 damper..
So I don't want to drill and tap with engine/pan installed..

I'll just put on the single replacement roller chain with
the 20195 melling pump

Just installed a double row chain on my LS1... giant PITA
Grind, check clearance, repeat.
I wouldn't have bothered, but I already had the timing set.
Skip it!
