Configuration question

[sittonb]

Planning a MKIV, 3 link, blueprint 347 hydraulic clutch, Holly Sniper

In the config section on FF5, would I need the following?
16921 - Hydraulic Clutch Throw-Out Bearing Kit (Note: compatible with Wilwood pedal box assembly only and requires Ford style Tremec transmission)

and what is
33862 - EFI In-Tank Fuel System+$625

seems like a lot, but maybe that's because I'm not sure what I'll need?

Couple comments. Obviously I'm not Factory Five Tech. But fair warning, this area is not actively monitored and pretty good chance you won't get an official Factory Five response. They have other channels, but unfortunately are very busy right now. If you want an actual Factory Five response, my experience has been email is best. But hopefully other forum members can also respond as I personally haven't purchased either of these packages. But FWIW:

16921 - Based on the description, plus the description on option 34158, Factory Five is selling an internal hydraulic throwout bearing where a hydraulic clutch is used. As opposed to a traditional cable setup. So you have a choice to make here. Do you want an internal TOB, or an external setup? Many use the external setup from Mike Forte. I've done both (internal TOB and Mike's setup) and from an effort and feel standpoint, really like the internal TOB. Have a Tilton setup in my Gen 3 Coupe. But you'll get lots of opinions about an internal setup. Most frequently cited are concerns that service requires the transmission to be pulled. Not going to debate here. Several threads available with searching. My opinion? You don't have to decide now. Either Mike's external setup or an internal setup are commonly available aftermarket parts. You can research and decide later when the time comes.

33862 - I'm only guessing, but for the price I would expect that means an in-tank pump hangar, the pump, and associated fittings, etc. Again, these are commonly available aftermarket parts and frankly I'd buy elsewhere. That way you can choose what you want and match your engine/fuel setup exactly. Probably for less money.

Based on my experience with the same options of the '33 hot rod, the hydraulic clutch option gives you the extra pedal in the pedal box, master cylinder and line. You then, as edwardb mentions, still need to supply either an external slave cylinder that moves the mechanical clutch fork OR a hydraulic throwout bearing.

The EFI in tank option will be exactly as edwardb mentions, an in-tank pump on a hangar and all the necessary fittings and high pressure line to go to and from the engine from the tank - EFI systems are higher pressure and at some point have a return to the tank. Lots of discussion on here as to the options on external vs internal pumps, where to put a regulator, return lines, etc. In tank pumps are fairly standard but there are pros and cons. Some tend to overheat and wear out quickly unless you keep a reasonable level of fuel in the tank. In the hot rod, it is a real bear to replace an in tank pump so I kept it external for my Holley Sniper. Some suggest an external pump is too noisy but I only hear it on startup before the engine fires as the exhaust far outweighs any pump noise.

Just to be 100% clear, the Wilwood pedal box Factory Five supplies with their kits (Wilwood 340-11299, Pedal Assembly, Rear Mount, HD, 6.25:1, Adjustable, Triple M/C) comes standard with both the brake and clutch pedal. The pedal box is actually designed out of the box for a master cylinder in the clutch position and a hydraulic clutch setup. The only thing needed is to add the appropriate sized master cylinder. Then a line to the trans and either your internal or external slave. Factory Five for years has been providing parts to convert the hydraulic clutch position in the Wilwood pedal box to a manual cable setup. It's a collection of cut steel parts and hardware that in the current version works well if you want to do a cable setup. I'm assuming their option 16920 includes these parts. This is a relatively new option. They used to supply the cable parts by default. Now they're giving you the hydraulic option.

To add on to what Paul and FF33rod has stated. I would recommend you also reach out to Blueprint for these questions as well. Some of these items might be included with the engine when you buy it. My 302, because I have power steering came with an external fuel pump. This was not listed on the Factoryfiveengines.com site. Also I found for the best answers Blueprint is great for transmission/ engine questions and then I used the forum and Factory five for everything else.

I HIGHLY recommend you just call Factory Five and go through the kit. They steered me away from things I thought I needed because it wasn't what I thought it was.

Now to answer your question as best as I can remember from a year ago. I'll also pull up my order sheet to make sure.

If you are buying the 347 with EFI and TKX-600 directly from BluePrint, you do not need the throw-out bearing kit. I have the TKO-600, but I don't suspect that this is any different. The BluePrint 347 EFI with TKX-600 kit that BluePrint specifically makes for the MkIV already has the throw-out bearing. You do not need to buy the throw-out bearing as it is already installed on the engine/transmission kit from BluePrint.

You do need the master cylinder for the kit. I purchased that. When I purchased it the part number was 34158 and was on the kit order form. "34158 - Hydraulic Clutch Master Cylinder Kit (requires customer supplied slave cylinder and hydraulic throw-out bearing)"

I also did not buy the EFI In-Tank Fuel System. The BluePrint engine with EFI comes with an external pump that will work just fine for your car. When I talked to BluePrint they said it wasn't for the throttle body type EFI like the one on the BluePrint 347. I emailed FFR about this option and they said it was optimized for a coyote install and not a SBF. I suspect it will work, but you get everything you need from BluePrint.

You also do not need the part 14227 Ford Style EFI harness because that is for a donor 302 from a mustang. The included harness from the complete kit is what you need.

Thanks to all for the info. In a way came to some of the same conclusions so I don't need either of the two just have to specify the hydraulic clutch in the setup form. Didn't expect so many responses, again, thanks to all!!
