i'm building a 402 iron block motor, coming over from the lt1 world. so this is all new. i was looking at the melling high pressure oil pump (p/n: 10296) and wanted to know what timing chains clear this pump and the ls1 front cover that are double rollers.

also do you need to run one with a thrust bearing or torrington that i've seen some kits come with.

 

I just used the LS2 chain with my stock (01 ZO6) gears. The links on the LS2 chain are thicker. I also drilled the block to install the timing chain damper.

this was the chain i was thinking about going with. any opinions on this one or others?

 

the new melling #10296 pumps are casted differently for better clearance with Dbl. row t/c sets. The new pumps are black in color and still should be looked at closely for chain interference when installing them. I have not used the new casting yet with Dbl. row chain set, but from the looks of it, it should fit alot better then the old casting did. All the JP Performance timing sets use and coming with torrington bearings.
