installed. The spare tire had holes for
six lugs; I filled them and drilled a five-
lug pattern, 7.
The kit engine looks good, but I
wanted something cooler than bare-
bones stock. A Tamiya Jaguar Mk.II
Racing kit donated a set of Weber triple
two-barrel carburetors I copied and
cast in resin (because I still want to
build the Jaguar!). I cast three sets and
cut up the first with a razor saw for the
primary flange, center carb, and intake
tubes. I drilled four holes in the flange
and added two mounting pins made of
stretched sprue that corresponded to
the inboard locator holes in the Chevy
engine. The other two outboard holes

were drilled to accept the stock exhaust

manifold, 8.

Brass pins added to the exhaust

manifold make a positive fit to the

block. I filled the outside holes with

stretched and then drilled them

(slightly offset) to receive the brass

pins, 9.

Brass pins strengthened the joins for

the two outboard carbs where they

were cemented to the flange. After the

modified exhaust manifold was

assembled, I test-fit it to the engine

block, 10.

A piece of .015-inch sheet aluminum

and foam from a meat package served

as the air filter. The aluminum can be

cut with a knife and straightedge —

make sure to use a blade at the end of

its usefulness. I cut a rectangle first,

then rounded the corners with 400-grit

sandpaper. The six pilot holes, drilled

with a pin vise and smoothed with a

rattail file, coincide with the nubs on

the carbs, 11.

I super glued the aluminum piece to

the foam. (Note: Some super glues can

melt foam; test a sample first.) A sharp

razor blade made the initial filter shape

and I refined it with a coarse sanding

stick. That was followed by a medium

sanding stick, 12.

The rest of the engine went together

stock and with Tamiya intermediate
