Awesome Scott and thanks. Looks like alot of my old school stuff is going up for sale, and I'm going with an LS motor.

3 questions.

1. Would it be easier to notch the frame for the A/C pump clearance. (Just me-Mark does everything the way I would if he was my best buddy and lived two doors down and I had the same type fabricating skills he does.) And, along the same lines, can we get the balancer with the reversed pullies from ATI (put the part number in at The ATI site-nothing came up-maybe special order)and the bracket Mark made for the A/C, does he have a template?

2. Headers- Those are very nice items from ATS, but 2 grand with shipping is steep. What, in the opinion of the learned folk here, is a less expensive alternative. The LS-7 is sweet, but this would apply to any LS swap.

3. MEFI4 ECM by MSD..Looked every where and can't find it on MSD's web site. Any help on where to locate this part?

Thanks Mark for all the pix and instruction.

The article was a informative read. Thanks

I'm thinking that was a misprint, unless he was speaking of this unit which may be based on the GM unit.

The MEFI 4 is a GM computer as far as I know. You can get them from the dealer or online places like Scoggin-Dickey, etc.

Yup... its a true Delphi/GM MEFI-4... but its from UMI.

The InGenius software, the MEFI-4 and the cable throttle body are from UMI's product line. MSD may pick the line up and be putting their own color and name to it in the future... but it is still UMI's product.

Is the dry sump tank "stock" unit ? Can same piece bought from ATS or Petersen? How about mounting?

I would be intrested of that balanced with ac pulley too!!!
