I've done quite a bit of searching on this topic, but I haven't really found a definitive answer yet. Is anyone running a ported LS6 oil pump with a JP double roller on an LS1? I wasn't really planning on swapping the oil pump when I do the cam install, but I found a great deal on one. Will there be any clearance issues I need to be concerned about?

 

I have a rollmaster double with a ls6 pump and the rollmaster came with shims to push it off the engine about a 1/16 -1/8 inch. The big concern some people have is the chain clearing the timing cover.

 

Did you have to clearnace yours?

 

I have the Rollmaster double setup with an ported LS6 pump and so long as you used the shims it works fine. I didnt have to clearance my timing cover at all either.

 

usually the stock front cover (ls2) is enough, but the aftermarket ones have to be ground. I have not seen an edelbrock one work yet for a double roller, grinding would put it through the cover...

 

My timing cover cleared too. I removed all the spark plugs and torqued the timing cover down and left the pully off and spun the engine over 20-30 times and then removed the timing cover and checked for any scrapes on the timing cover.

 

Yea edelbrock and qtp as well from what I heard require grinding on a double row.

 

well i have not heard of an edelbrock working at all. the qtp will though.

 

I have the LS1, not the LS2.

 

I will definitely be doing this.

 

I've used some Katech LS6 pumps before with JP t/c sets and clearance was pretty decent with the supplied spacers. It's tighter with a melling though.

 

Why don't you stop in someday Nick. I have a new single row t/c set from PROGEAR now, that will do the job perfect for you.

 

Funny you say that Joe. I was planning on stopping by in the morning if the weather is nice after the rains tonight. I have a real itch to get the car out.

 

I don't get there till after 11am, so make sure you come after that.

Thanks, Joe

 

Damn man, must be nice to have banker's hours!

 

rollmaster and ls1 front cover here.
all is well.
