[DeTomaso] Weber manifold question

[wkooiman at earthlink.net]

The intake might be listed at Hall, but I doubt they have any.  I haven't tried, but it seems like 351C Weber intakes are very hard to obtain.

I have a Hall/Inglese Weber intake for A3 heads.

It is identical to a Hall/Inglese Weber manifold for 4V heads EXCEPT it matches A3 ports perfectly.

The A3 ports, as you know, are raised, wider and shorter than 4V ports.

It would be a lot of work to port match to C302B heads.  The C302B ports are much more square.

If you tried a 302 Weber intake, you'd have to:

a)  Cut it in 3 pieces and fab a valley pan (weld or use a 3-piece arrangement)
b)  Port match
c)  The bolt holes are different.  They're close, though.  W intakes have bolts that are perpendicular to the ground.  The middle 4 bolts on C heads are perp., but the rest are about 30deg.
d)  You'd have to do something with the water crossover in the front.  Cut it off, or switch to a W style.

I don't see this happening without being a hack job.  I couldn't do it.  A machinist could probably do a good job.

One idea is to call Kinsler.  They list a 3-piece manifold/throttle body for SB/Yates.  It's probably pretty close to the C302B heads.

This manifold is currently rarer than rocking horse s*it, however Aussiespeed are supposed to be recasting it in the very near future....like February at last contact.
