Timm,
I fitted the Goodparts triple stromberg kit to my '71 a few years back,
and am very happy with it. The fit and finish of the parts was
fantastic (as has been my experience with all of the Goodparts parts
that I've purchased). Price can't be beat, compared with triple webers
or fuel injection. They are easier and cheaper to tune than Webers,
and will flow more than dual SU's. If you don't like Strombergs (or
you just want the benefit of the ample needle selection available for
SUs), you can bolt three SU's to the Goodparts manifold.
That said, I don't think this conversion is well suited to a stock
engine. This is really something you want to do AFTER you've already
done a cam, head work, and exhaust. I would start down these avenues
first, as the stock dual strombergs will cope fine and you'll get a
sweet bump in power. I ran dual stroms with a Goodparts GP3 cam,
ported/polished head with 9.5 compression, header, and 1.65 roller
rockers. The car was a hell of a lot fun. Then I added the triple
strombergs as a final step, and this seemed to add a few ponies (though
I have no dyno tests or performance data to back this up).
Bottom line - if you are looking for more power, start with the cheap
and easy first (K&N filters, free-flow exhaust, convert to electric
fan), then get a header, then do cam/head. Last step would be carbs.
