I've done this before but have forgotten, how do you pull the timing chain and gear off this thing?

Remove camshaft chain tensioners. Set crankshaft at 51 deg BTDC. Remove front and rear camshaft retainers (two each camshaft) including thrust washer on within front camshaft retainer. Tip camshafts up from rear and slide timing chains off camshaft sprockets.

I mean the main one that looks like a regular 350 timing chain.

There are three bolts in the Timing Chain Idler Sprocket...maybe this will give you a clue ;)

I think the primary crankshaft sprocket for the Timing Chains will slide off the crankshaft (there is a key in place to keep it locked to the crankshaft rotation).

Oh....remove the main timing chain tensioner to give you some slack in the Main Timing Chain.

Took the three bolts off already and the tensioner, I already did all that before asking. but thanks for being condescending.

I wouldn't say that's condescending. Cliff is very helpful.

Perhaps it was Cliff's post including "maybe this will give you a clue" that seemed condescending? In Dan's defense I'd have taken that comment as less than constructive as well.

Cliff is an extremely nice, intelligent, kind, decent and witty kind of guy.
I can personally guarantee he meant no offense.

If you took the 3 screws off the main cluster gears have a center dowel it's probably stuck you might need to work it a bit just make sure your clear of guides etc work it out it will come off.
