Engine Mount

Below is the MKII mount.

June, 2003
Our replacement engine mount from the boys in Indy showed up and is painted........... man, what a beaut! We started out with the MKII mount and purchased the Indy mount when it was available. As you can see from the photos the welding and structural integrity surpasses the MKII mount. I’m confident the MKII mount would perform adequately........ but as Bob Gross (Rocketboy) would say........ the Indy Mount is “Adequate Overkill!”

The gray (light colored) mount is the Indy mount and the sliver (darker colored) mount is the MKII. Look closely at the tubing placement. The MKII mount cuts one tube at angles and welds it to the second tube, where the Indy mount gets the full benefit of both tubes structurally.

Below is the Indy Mount ARRRRR!!

Mounting the engine mount 06/2006

The firewall is pre-drilled with undersized holes for the engine mount. We used 3/16 allthread rod and nylon bushings to hold the mount in place while we "match" drilled each hole. Our "Indy" engine mount came pre-dilled assembled with 3/8 (firewall) mounting holes.

Nylon bushing is 3/8 OD...we had to drill the inside of the bushing a #10 bit before the allthread would fit.

Per Mark's instructions, updrill the lower right-hand hole to 1/4 (freehand), then 3/8 using the engine mount as a guide.

Updrill to 3/8, once again using the engine mount as a guide. Yes, the engine mount was installed and removed several times during this process. This helped to maintain hole alignment throughout this process.

Sanity check - looking good so far!

Up drill upper left-hand hole to 3/8.

Use the nylon bushing and a long drill bit to begin the updrill procedure on the last two holes.

Mounted! We'll need to fabricate a "filler" between the firewall and the two center mounts.

SHOP TIP - while drilling the lower left hand hole to 1/4 use an assistant and a bolt in the lower right-hand hole to help guide the drill operator to the appropriate angle.

Up drill upper right-hand hole to 3/8. Notice the "bushed" allthread in the remaining 4th hole (upper left).

Last hole was lined up fairly close - still required the "malletizer."

SHOP TIP - Once the hole is drilled to 1/4 inch, use a "Unibit" to updrill the stainless firewall (not the aluminum bracket) to 3/8. It will make a cleaner cut as opposed to using a standard 3/8 drill bit.
