I want to thank all the folks that answered about a million questions that I had during this upgrade. I finally finished it today and now I am just waiting on my RJM EFI harness and I might be on the road shortly.
I wanted to put some pics together and share some of the bumps in the road that I had with my particular application.
What I started with:
Ford Motorsports 351W crate motor (M-6007-S58) that I had setup with carb. Started my SEFI swap and Serp swap at about the same time.
JBG Aluminum 4 core radiator (Howe) with AT cooler.
What I bought:
Serpentine brackets/pulleys from a 1993 Mustang 5.0
A/C eliminator bracket for 351W.
Ford Water pump for Mustang (reverse rotation with DS inlet)
BC Broncos 17" Derale fixed blade fan (CCW)
1/2" Fan spacer
How it all went together:
Serpentine brackets were a direct swap and bolted right up to the waterpump and heads. Pulleys bolted right up. I swapped my V-belt PS pulley for the Mustang (I am running a late model Ford PS Pump). All the brackets and pulleys lined up with no spacers required. I also upgraded to a 160 amp 3G from RJM (can't beat his price) at the same time. You have to notched the alternator bracket slightly to allow the 3G to fit (see pick). A 1/2" fan spacer is plenty to keep the fan out of the belt (might be different with a flex fan). With my setup (PS, Alt, WP, Crank, A/C eliminator, no smog pump) I needed a 77.5" belt (Dayco 5060775).
You have to notch the stock fan shroud around the tensioner pulley arm slightly (about 1/2 - 3/4 inch).
The main issue that I ran into with the upgrade was due to my aftermarket aluminum radiator (you will probably not have these issues with a stock radiator). Since mine was about 4" thick, the fan ran way to close to the radiator at the bottom. I put a BCB fan guard on the radiator and the fan hit the guard. The solution was to cut the bottom mounting bracket to slide it back about 3/4 inch. I also made new upper brackets to pull the radiator closer to the core support. Now I know many of you have cut and moved the core support out (I would prefer to do this too) but I suffer from an acute case of "lackawelder". So I had to make due.
So now everything fits. The question of serpentine upgrade is raised here every now and then and since I did this on a 351W and is somewhat different than the 5.0 upgrade, I hope it may help some others in the future.
Here are some part numbers for reference:
Upper radiator hose: Goodyear XL60625 (1968 Pontiac GT with 400ci)
Fan belt: Dayco 5060775
Water pump: FMS-M-8501-C50
A/C Eliminator Kit: FMS-M-8511-A50 Accessory bracket P/S: FMS-M-8511-A351
