[Tigers] CAT Headers and alum heads

[Gary]

Tom,
 
I use the Edelbrock Performer PRM intake manifold, but with a Baldwin Motion
Fly Eye air cleaner
under the stock hood, no scoop. However, I have not tried it with the factory
air cleaner, may well be too tall. Then again with all the talk about the
factory air cleaner being stolen, that may be a good thing.

Allan,

What size heads are you looking at? There are size constraints built into
the Tiger.

I'm using Edelbrock E-Street heads (not planning on racing or anything
extravagant) with Sunbeam Specialties headers. They're the same size
externally as the Edelbock Performer heads but without the polishing. I
measured against the stock heads, same external dimensions, larger
rectangular ports. The headers were about the same size as the Edelbrock
ports.

If memory serves Ford Windsor size heads wont fit under the Tiger firewall
(I'm sure you know this but it bears repeating) and the Edelbrock Performer
RPM Intake manifold is too tall to allow the carb to fit under the stock
hood. See Tim suddard's article in Classic Motorsports.

Looking at my SS headers I have to say no, they can't be enlarged. The tubes
are so wide that they used 1/8" hex head bolts and it was impossible to get
a socket on two of them. If you were to "square up the ports on the stock
Ford heads you'd be into the bolt holes.

I can send you pictures offline if you wish showing the port size of the
E-Street heasd and stock Ford heads. I think rthey'll show what I'm trying
to explain.
