|Motor is assembled and reinstalled|
I started by making a list of parts that would be needed for the rebuild. Of course the parts that failed would need to be replaced, but some parts are only available in engine sets, so there was some decision making to take place.
Pushrods: I had always used Ford Racing pushrods on all my motors and had never had an issue. So I ordered a full set to replace the Comp Cams ones that had failed.
Rockers: I called Lunati Cams and they were able to set me up with two new roller rockers to replace the damaged ones.
Gudeplates: The AFR guideplates are sold only in a set of eight, so that is what I ordered from Summit Racing.
Screw-in Studs: I picked up a set of ARP studs from Murrays Speed and Custom in WPB. The ARP units are far superior to the ones AFR included with the heads.
Roller Lifters: I picked up two Sealed Power units, as the others were fine.
Motor Mounts: The polyurethane of the drivers-side Prothane mounts that I had been using had started to bulge. So, I ordered a new set from Summit Racing.
Gaskets: Ford Racing Oil pan gasket and Fel-Pro everywhere else. I normally re-use valve cover and exhaust gaskets, but this build was a little different, as you will see below.
The new parts and gaskets for the motor started arriving pretty quickly. There was clean-up to do first. All the old gasket material and RTV would need to be removed from all the mating surfaces. The first parts to go back in were the camshaft and timing set, followed by the front cover, water pump, harmonic balancer and pulleys, followed by the freshly cleaned oil pan to button up the bottom end.
heads were given a light cleaning and the new AFR guide plates and ARP
rocker studs were installed using PST. The Fel-Pro intake gaskets that
I installed last time were still in great shape and just needed to be
cleaned up and they were ready to go. Before the heads were bolted-on,
the lifters, dog-bones and spider were installed. The heads were
torqued down using the ARP head studs, lubricated with ARP moly paste
for a proper torquing. The new Ford Racing pushrods and Lunati rocker
arms were installed and the valve lash was initially set at 1/2 to 3/4
turn past zero lash. The intake manifold installation completed the
headers, oil filter, spark plugs and dipstick were the first
accessories to go back on the motor. Next 8 quarts of Valvoline 20w50
VR1 racing oil went in the motor and it was primed using a oil primer
tool and an drill. The distributor, plug wires, front accessory
brackets and engine wiring harness were the final items to go on before
the engine came off the stand and went on to the hoist.|
|Once on the hoist, the block plate, flywheel, clutch disc and pressure plate were installed, and the engine was swung into position and lowered into the bay.|
several minutes of wrestling, the engine was bolted up to the
bellhousing and the rest of the accessories could be bolted on.|
|With the engine bolted in, here were some issues that I ran into. |
When unbolting the oil pan from the motor, two of the nuts were frozen onto the studs. This was a brand new set of Canton studs that I had been used just once. I called up Canton, who said they would ship out some replacements right away. The didnt arrive.
I ended up picking up some replacements at the hardware store.
Next was the header gasket. Last time I put the headers on, I used a new set of Ford Racing gaskets, rather than Fel-Pro. When I prepped the headers for installation this time, I noticed that the gasket port opening was lower on the top than the opening of the header. I picked up a set of Fel-pro 1415 gaskets and that solved the problem.
Finally the new motor mounts I installed changed the position of the motor relative to the chassis. The motor now sits 1/2 inch lower and 1/4 inch further back. This caused a problem with the bolt-in cross member on my Maximum Motorsports Tubular K-member. I had to install a large shim in order to give the oil pan enough clearance now.
That's all for now. My next race is at Daytona International Speedway on May 6th & 7th.
