help, where can I get a heavy duty 5 under timing chain/timing chain set Alright after getting my splayed mains done and everything else. I am told I will need a 5 under timing chain and was told the timing chain set will probably run about $400!!! I need a pretty heavy duty one since I will be spinning to 7000rpms and not sure if this matters but my springs have alot of open spring pressure. If it matters I will no longer need the waterpump gear since I am running an electric waterpump. Thanks for any help.

I just can't figure what he was talking about when he said $400. I know he had asked are you still using your optispark. Not sure if that makes a difference. Anyhow so these should be plenty strong enough for my high rpms? Also I was reading the specs on these and it says Maximum Advance/Retard at Camshaft is 2 degrees and Maximum Advance/Retard at Crankshaft is 4 degrees. I assume my builder will just set these up for no retard and no advance since mine is computer controlled.

when he degrees the cam he'll be able to advance/retard by the crank gear, offset bushing or adjustable cam gear if you get one of those fancy billet units. The 3145 is a good piece, and ALOT of people go with it when they go double roller. I ran one for almost 25k miles with lots of trips to 6800+ and it came out looking fine. I went with a billet comp unit this go around only because my builder had a new one laying around.

your builder is probably referring to the heavy duty single roller.
heres a link to it http://www.summitracing.com/parts/CLO-9-3151/
... with the double rollers I posted previously you will have to do some clearance grinding on the timing cover so it will clear the dbl roller chain..
