Kris,
S1
Bluebird has about the largest runners and base holes of any of the L4
downdraft manis and a S2 Bluey could be the same but I don't know anything
much about the technical specs of them. There isn't much to be gained simply
by fitting a larger runner manifold unless the head ports are at least
the same size, some A87 heads have 38mm ports. There are a few holes to
weld up if you use a L20B mani as they have EGR etc - not hard to do
though.
Usually a 32/36 will run well with 12-14 degrees of initial advance on
the Bluey S2 dizzy with vac advance connected and 96-98 octane so if
it's not detonating then it's pretty close to where the engine likes.
Usually going up hill at around 4000 rpm at WOT in 3rd on a 40 degree day will
sort it out.
regards
Terry

Subject: inlet
manifold
Hi all,
I
have a 32/36DGAV on a L16 manifold on my L18SSS engine and seems
too restrictive. I believe there is manifold from an L20B engine that is
better suited. The head is an A87 but i don`t know if it is the larger
or smaller port head. Can someone tell me which car this
manifold would be from please.
Also, i have the elec. dizzy
and was wondering if i set the timing at 14 deg BTDC will this provide too
much total advance with the vac advance hooked up? The car doesn`t ping
though. I have two timing marks on the front pulley, one lines up with
0TDC and the other lines up with 15Deg BTDC is this the correct way to
set up the timing? I have never seen this before on a factory
engine.
I use Caltex
Vortex Premium 96 octane.
Sorry for rambling on.
Much appriecated,
Kris.
