Some photos of the intake manifold for
the 20B are attached. It is 4.5” from flange to flange; the TB flange is
at a slight angle to fit my installation; the TB is TWM 3003; 44mm diameter bores.
Another builder built his from my
drawings and had a couple extra made. At least one is still available.
The price is around $1000; I’ll have to check. That’s a real deal –
by the time I had mine fabricated and heat treated it was over $2000. Let
me know if anyone is interested.
