Peterson can make you any size tank you want in 6", 7" and 9" diameter, and they will weld on any size AN fittings that you want as well. For instance, one option for one of their 2 gallon tanks would be 7" diameter and 20" tall. So it's a matter of measuring what space you have and getting the packaging you want. ATS is a dealer for Peterson, so you may want to talk to Tyler about what he can do once you know what you need.

As for mounting, it uses straps that you can secure to the core support or where ever you want to mount it.

Great article Mark...and thanks for adding it to the site Scott!!

Hello Scott!

Thank you for clearing this. Since there are now few LS7 projects going on i will see if others will use same set up and the order one. I will needed it quite soon so we can build place for it. I will ask it from Tyler. I need to double check what AN fitting those adapters are wich mount to stock pan.

Isn't the MEFI-4 the GM "Marine" computer? If so I though the problem was it's lack of flexabily (limited functions, no OBD port, etc.)

I'm not sure, Steve. I went with the E38 ECM.

So did I. I almost went with Turn Key's harness since they were on of the few that supported 58x. Then I found (as I remember) that they used the MEFI4 unit and that it's capabilities were far less than the E38. It's not a huge deal if you don't care about those functions but I wanted the OBD port for easy diagnostics and tuning. I don't think the MEFI4 does anything with the trans either. I will have to research this a bit today.

I that Speartech?

Jim, the E38 is the factory ECM. Speartech offers a solution, very knowledgeable guy. :thumbsup:

In my case yes, they simply have the best, most flexable, product and John is GREAT to work with.

Can anyone confirm whether the custom balancer and A/C pulley that ATI did for the LS7 would fit/work on an LS1?

thanks
