Putting the prop flange at 44" in front of the firewall puts  it

5" in front

of stock.This requires that you make a new engine cowl. My cowl

differs from

the stock one in that it is 5" longer and is built to provide for

a 14"

spinner. It has no cowl cheeks and is rolled  from .063 6061

aluminum on an

english wheel. Most of the  ideas on the design of the cowl were

based on

suggestions from Everett Hatch.

Sounds like this is going to be a mini WWII fighter when you are
finished.
Will you be Polishing it? What is the source for your 14" spinner, 
the biggest I saw in the Aircraft Spruce catalog is only about 12".

At this point, I'd like to solicit advice- do I go to two  2" I.D
wrapover tubes, (4 into 2) or  four 1 1/2 " tubes (4 straight

tubes)? In

using  two tubes, I'd have one tube feed the front chamber and one

feed the

rear.   I assume that all the runners would end up in a dynamic

chamber

somewhere  near the plugs. And do I make the  runners out of

aluminum or lay

them up out of fiberglass? Anyone?

Can you get thin walled mandrel drawn steel exhaust bends? Wouldn't be
much
of a weight penalty and would be easy to weld.

Hey guys please set your left margines to zero. If you don't it makes
a mess when you quote messages. Takes me a long time to clean it up.
