A 351+ with good heads and proper choice of parts
will give your brothers 390 a run for its money. Keep
in mind that, ultimately, cubic inches rule on the
street. You should also never underestimate the potential
of an FE motor. A purpose built 390 with all the
right toys will make an extraordinary amount of HP and
turn alot of RPM. If your brother's 390 is really well
built it'll be a tough one to catch. If its just a
warmed over stocker with untouched GT heads then should
be able to keep up with him. If you can afford a
stroker kit and good heads you'll be well on your way to
a fast small block motor.<br><br> You should take
advantage of modern technology and get better heads, a
modern roller cam/conversion and use a stroker kit to
increase displacement.<br><br> Go on-line to Summit Racing
(and others) and to some of the 5.0 web pages and
start looking at aftermarket heads and stroker kits to
get an idea on what its all going to cost. Its not a
matter of what its going to cost, but how fast can you
afford to go?<br><br> TFS, World Products, DART and even
Ford offer high quality heads that are leaps and
bounds ahead of the fish weights you've got on the stock
289 motor now. Don't waste your time considering
porting the heads you have, the money is better spent on
new heads. A modern roller cam needs to be used to
take advantage of the air flow the new heads will
supply. Keep the compression between 9.5:1 and 10.0:1.
Use a good dual plane intake and a 750 vacuum
secondary carb or EFI if money is no object.<br><br> Do not
skimp on machine work. I see people spend thousands on
great parts only to have a hack of a machinist or
engine assembler ruin it all. Go to the local drags,
cruise-in's and other places in your area and talk to the
folks that consistently run hard. Find out who's been
doing their machine work and building their motors. Ask
about the quality of work and how the motor runs. Ask
lots of questions and get lots of opinions and input
before you start having anybody start the machine work.

I'd be happy to guide you through a typical
performance build up. <br><br> -Mike.
