My friend, "Dr. Bob" wants me to build him a 1/8th scale Exterminator powered by two Ford 427 SOHC engines.

Body is to be painted Ford Guardsman Blue with 2 white stripes.

Starting with the 1/8th scale Lindberg Exterminator plastic model:

Here's a preview of the parts I will be using from the kit:

I was able to locate a couple of 1/8th scale resin Ford 427 SOHC engines from

Big Scale Dreams. https://www.facebook.com/pages/Big-Scale-Dreams18Ford427SOHC1-vi.jpg

Here is a photo of all the parts which come with each engine:

Now, onto cleaning up the parts and seeing how everything is going to fit.

dang...this thing is going to be BIG!

thanx for looking...

One of my concerns on this project is the weight of the resin engines resting on the kit's plastic chassis.

I went about removing excess resin from the parts to reduce some of the weight.

For the chassis to clear the engine, I had to raise both engines 1/8th of inch.

I fabricated motor mounts from 0.30 sheet styrene using the mounts from the kit as guides.

I then attached the kit's bell housing 1/8th of an inch lower on the rear engine.

Painted the engine Light Blue Ford Engine Blue...as the paint dries, back to the bench.

I compared the cast valve covers to photos of them and realized cato was right...a little work was needed to get them right.

here's a photo of the cast valve cover and a reshaped one:

Here's the front engine painted and partially built with parts,

waiting for my order from RB Motion (spark plug/distributor boots along with assorted nuts/bolts) to arrive.

Rear end with backing plates/drum brakes painted.

Want to put some "Zoomie" type exhaust headers on the motors similar to these:

sohc2241-vi.jpg

Failing to find 1/8th scale Big Block "Zoomies" on the WorldWideWeb, I realized I'm gonna have to build them from scratch.

Easy - right! After failed attempts using a tubing bender to get a decent bend in 1/4" brass and aluminum tubing, I went with plastic tubing.

Found some 1/4" Plastruct Butyrate tubing at the local hobby shop. Made a jig from wood to bend the rod using a heat gun to soften the butyrate.

​Now I need a way to get all 16 headers to be the same size, I resin cast a jig to assure each header was the same size:

ZoomieJig1-vi.jpg

ZoomieJig2-vi.jpg

​Just saw off the tubing that protruded from the jig and bingo...zoomies

​Just need to bore out the ends and attach to the header flanges.

Both engines are nearing completion

The only modification I see forthcoming is shortening the front crossbeam on the chassis because, the Ford 427 SOHC with the distributor out front causes the front engine to sit further forward in the chassis.

more to come

Yes William, it's the same model...I got in some serious "bench time" the week before the NNL West.

Now that the NNL West is over, and a great show it was as always...here are some updates on the model.

I created another jig for the zoomies to help getting them pointing in the same direction and attaching the header flange.

Sixteen Zoomies ready to go...

I forgot to take photos of the engines prior to mounting them in the frame rails. Just got rolling on assembly and the next thing ya know every things in place.

Spark plug boots are from RB Motion http://www.rbmotion.com. Blower belts were cut from a bicycle inner tube.

Awaiting delivery 1/8 scale nuts and bolts from Shapeways/TDR Innovations http://www.shapeways.com to finish detailing the engines, etc. Got my buddy Steve working on a "Dr. Bob's Special" decal.

​thanx for looking'...back to the bench

Oh yah, did I say this thing is BIG?
