Yesterday, I received the Boss 302 heads for my build. The runners and chambers are CNC ported and look great. I should be able to start engine assembly next week.

2012 Mustang Boss 302 Block Prep for engine build!

admin — Thu, 15 Mar 2012 00:57:00 +0000

I finally received the coyote 5.0 block. It was discontinued by Ford Racing and is supposedly pending replacement by a revised version. The new block will no longer have the option for oil squirters and uses a slightly smaller diameter head bolt. I wonder if there was some weakness in the deck of the previous block that necessitated the head bolt revision?

This discontinued version of the block as part number M-6010-A50L4V

One thing that I noticed right away was that many of the machined surfaces inside the block had numerous burrs and shavings just waiting to fall off into the engine oil. Technically, these should get picked up by the oil filter but why chance it?

I used a small round file to knock off all of the free/extra aluminum that Ford had to offer. I’m more comfortable with it on the floor of my garage vs my oil pan.

Received some of the basic short block parts for assembling the Boss 302 engine. The block itself is backordered until later this month. Everything looks as it should. I’m going to get some of the other internal engine parts ordered up this week and should be able to assemble the engine as soon as the block arrives. I also picked up the Boss 302 oil pan.

It’s hard to beat Tousley Ford pricing – ask for Steve and tell him Jeff Foster sent ya!

2012 Boss 302 Seats Installed in Fox Coupe

admin — Tue, 10 May 2011 03:38:56 +0000

I finally got these installed. I used a set of stock fox seat tracks, sliders and springs to mount the Boss 302 seats in the 93.

First, remove the OEM seat tracks from the Boss seats.

Note, the OE seat track for the drivers seat also had a manual control lever that is integrated into the track. You must remove the lever and then use the cap that originally attached to the lever to fill the empty hole.

The Fox seat tracks mount to the seat on a 14″ x 14″ square pattern. You can see here that the stock track rests on an edge that is on boss seats. This was just about right.

I riveted the tracks in first to test fitment.

Finally ran bolts with lock washers and this was the result.

Sorry about the poor lighting. Next is to get some suspension back under the car – then some outside shots!
