I have the original carbed 302 in my 79 with factory Duraspark ignition. I want to swap to a roller 5.0 block soon and want to keep the Duraspark. I recently spoke to a certain distributor company to order another Duraspark distributor (mine has a lot of wear) with a custom advance curve, and...

Does anyone have a link or chart that shows how many amps a given wire size can handle and how to determine proper fuse size? I'm finally getting around to doing the 3g alternator swap with one rated at 160 amps. (tested at 177 amps max) from alterstart.com. Most articles/posts I've read...

Has anyone mounted their aftermarket fuel pressure regulator directly to the back of aluminum aftermarket fuel rails? I know the stock factory setup is like this, but the mallory fpr is much heavier then the stock unit and I'm concerned that the extra weight and vibration would crack the fuel...

I realize a distributor needs a certain type of gear so it won't be damaged by a steel roller cam. My question is, can a TFI style distributor be used with an older flat tappet style cam without causing any issues? Thanks.

Does anyone know of a source for a deep groove V-belt pulley for a 3G alternator? I read somewhere that the v groove belt slips on the 3G when it gets over 100 amps. I don't really want to change over to a double groove or serpentine just yet. Just trying to cover all the bases before I begin...

I'm looking for a source for -6 and -8 tube nuts and sleeves for use on 37* AN flared steel line. The ones I see at Jegs and Summit appear to be used only for aluminum hard line. I've found a couple 37* flaring tools as well, rigid and parker-rolo, but they are also meant for softer copper /...

Hello. Does anyone know if the A9L or A9P can be tuned so the injector sequence and firing order will be the same as the firing order used on the older 302's? Thanks.

Has anyone used nylon fuel line from tank to engine in place of the factory steel line? Trying to find an economical way to mate the springlock EFI fittings to the factory (carb) steel fuel line, but haven't had much luck. I'd like to use steel or stainless steel, but have been considering the...

Anyone familiar with Mass-Flo Fuel Injection Systems? It's an aftermarket EFI system that uses mostly Ford electronics, A9L, TFI, MAP, TPS, IAC 02 sensors, ACT, VSS, injectors, etc. It does us a 85mm GM style maf, and custom 1000cfm throttle body. I was very impressed with everything I've...

www.retrotekspeed.com It's a self programing efi system that looks like a carb. Sounds too good to be true, but the way technology is today, who knows. They don't have a price listed yet.

I'm planning a 5.0 HO efi swap to an older vehicle and ready to buy headers. I'm leaning towards Ford Racing shortys. (M-9430-P50) My question is where are the o2 sensors located, in the header collectors or on the down pipes? Thanks!

Here's the receipe and the goal. Any advice is greatly appreciated! Converting older, daily driven F100 to EFI. Looking for a little more performance while maintaining reasonable fuel mileage. Originally planning on a mildly modified 89-91 Mustang 5.0. (It would reach my HP/TQ level but at...

I just received a "stock" 94/95 mustang maf I ordered on Ebay. Just below the platform where the electronic module attaches, in a recessed area, "JAPAN" is cast on the aluminum housing. It has the factory module attaced to it (F2VF-12B579-A2A), with a "remanufactured in USA" sticker on it...

Hello. Im swapping a 90 mustang 5.0 into an older truck and will be using a 95 Mustang maf. I'm fabricating a cold air inlet using the existing opening in the core support just beside the radiator. Since this kinda acts like a ram air effect I'll probably fab some type of diffuser or shield...

Hello. Does anyone know where I can find the the transfer functions for the stock 90 mustang maf (5.0 55mm) and the 94/95 mustang GT maf? (70mm not cobra) I'm not quite ready to spend $300+ for a pro-m 80, and this seems like a reasonable alternative. I would also like to see some air flow...

Hello. I'm planning on building a 90 mustang 5.0 EFI to swap into an older Ford. I want a little more power than the stock 5.0, but don't want to go too far to create lean air/fuel ratios, surging and other driveability issues. I'm not trying to squeeze out every last hp but want a reliable...

Can I get away with running the stock 55mm maf with a T. Moss ported stock lower and Thumper head combo, or will I run into lean afr and driveability issues due to the additional airflow? I realize the stock maf is a restriction, and would like to go with a larger one at some point, but I've...
