1966 Ford F250 Truck 352ci V8 5.8L Driver & Passenger Side with 2 Inch Outlet Exhaust Manifold 2 Piece Set TRQ EXA51594

Guaranteed to fit, but it is not to OEM specifications. It was immediately apparent how different from the 1968 manifold it is. The mold was sloppy, excess flashing material in the ports, cut surfaces not properly finished. However with some modifications, it made do. I was not in a position to return it and wait. Clearance for the bolt hole set in the exhaust fork did not allow for washers. Spacer necessary. Threads below the flange required different bolts from the ones removed. These Chinese facimiles may fit, but a junkyard might be a better option

Manifolds did the trick and at a reasonable cost. Would have liked the ability to include the gaskets, new bolts and donuts, which are needed but not included. Overall, very satisfied. Thanks.

So i was hesitant to buy these at first with some of the reviews. One reviewer said that he had to modify them to make fit. I didnt have to modify them at all and they fit perfectly. They seem high quality. I have two other 360 engines that i will be purchasing these for. One of thing i wish they came with are the studs for the exhaust pipes. Other that that i love them.

Quality of the casting was marginal. The right manifold was fine the left was out of tolerance by over 1/8 inch. Making them work with extra gasket.

The finish had some flaws but they fit! Thanks

When I received the pair, there was a questionable quality issue with one one side. I contacted A1 and they sent me a replacement. The entire process was quick and smooth. Thank you A1.

Arrived fast and fit perfect

This was our first time ordering and no one could ask for a better experience. The parts staff was very knowledgeable and willing to explain other options. I know we will be ordering more parts and your company has been hands-down the best to deal with. Order was shipped out almost immediately and received within three days! Awesome job! Thank you!

Haven't installed yet but the quality looks very good for the money.

I ordered these for my 1965 Galaxie 500 LTD. It has a 390 out of a 1974 F100. The left side fit perfectly but the right side needed a slight downward angle to fit, so I couldn't use the right side manifold. Luckily the left side was the one I most needed to replace. I'll just sell the other one online.
