<DIV>numbers may say one thing, but I think the best test is the “seat”
test. have first put the triples on a stock engine, then done quite a lot
of other mods, I’m going to say the seat test says do it.</DIV>

<DIV>I still say study the numbers. Even a high performance TR engine can't
flow what two Stromberg's can handle.</DIV>
<DIV> </DIV>
<DIV> </DIV></DIV></BLOCKQUOTE>This is quite true, on the numbers from the
flow bench of just the carburetors and just the head. I would say,
however, that there's a small advantage in having each carburetor servicing two
runners, instead of three, if only because the runners are straighter, and the
pulses from each carb will be a bit sharper and better-defined with three
carburetors instead of two. Flow numbers aren't everything--they matter,
but so do mixture distribution and mixture uniformity. My guess
is--because of the upper limits on flow of the head--there wouldn't be a great
top-end power increase, but the low- and mid-range performance would probably
improve some, and there would be slight torque improvement because patchy
mixtures delivered to some cylinders would be reduced.<BR><BR>That said, the
difference is going to be small, because of the port limitations of the cylinder
head. Is the improvement worth the money? That's probably
subjective. A hundred bucks a horsepower is pretty dear for the occasional
driver. For the NASCAR guy, it's a bargain.
<BR><BR>Dyno comparisons on the same engine would probably tell the
tale.<BR><BR><BR>Cheers. <BR><PRE class=moz-signature cols="72">--
