Hi, George....yes, I am only using two large injectors.  They are the

same

as Dave Atkins in using. (I purchased the throttlebody, EFI, etc from

him).

As far as the tubing goes, I tried to copy a wrap-over manifold that I
purchased, but could not use because of cowling clearance problems. I

made

my manifold with slightly larger intake diameters, and approximately 5

1/2

inches longer than the "factory" intake manifold, so my best SWAG

(Stupid

Wild-Assed Guess) is that since I am only extending the runners by about

5

inches, and increased the runner diameter approximately 1/2 inch, it has

a

chance? Attached you should find a picture of the manifold I tried to
copy/improve upon. I hope this works OK, as it gives me plenty of

clearance

above the engine in this configuration. I also tried to make it look
something like the Powersport and Racing Beat's aircraft engine's

intake. I

should know in a couple of months.  I'll be happy to give a report

....good

or bad.   Paul Conner

Paul,
 Don't be shy in letting us know how it performs, I will be looking forward
to your report !
BTW it looks pretty good.
