Heads Up - Holley might be closing out the 660 Center Squirter again

[Drew Pojedinec]

Drew, does this mean you'll be running a sale to compete with Holley? If so, sign me on

Well, I've got 4 sets of 600's that are not spoken for now.  I think I do more 2x4 600's than anything, did I think 20 sets last year, they seem to work really well.  I'm not too worried, they'll find a home in the next month or two.  Just trying to get them assembled and tested, then they can sit.

Best one of the year tho, a fella built a 40k+ engine and wanted me to build custom 780's.  Seemed a good idea considering the engine was like 530ci.  Anyway, he backed out because he could save some money by running two street avengers.  I wonder how that worked out

You will never hear about it.  The next carb guy he decides to order from after it underperforms will hear about it.

As for the 660s - - "running out of stock" is corporate code for "we screwed up on the price"...

Could anybody remind me why the 660 is so much more desirable than a 750DP or Ultra or whatever? Thanks.

660's can mount inline on a stock 2x4 Ford intake.  For such a mounting arrangement, they are hard to beat.

Any idea how more power they make on said 2x4 over worked 600's?

[Drew Pojedinec]

Obviously it would depend on the engine.
That said, I've known a few with 800-900hp engines that claim nothing is faster, and they've tried them all.  *shrugs*  it's all beyond my budget.

On a somewhat unrelated note, I'll have a set of these new 660's here tomorrow, and can compare the calibration with the original ones to see if they are on the same level.  I'll especially be interested in the emulsion tubes, as they haven't made the originals since the 1960's, the later tubes are vastly different.

Is there any reason sideways-mounted DP's would not outperform 660's?

Back when Jay was dyno testing intakes for his book I think there were a couple intakes he tested with both the 660 Center Squirters and a pair of BJ/BK Holley 600’s, and if I remember the 660’s won out. They probably wouldn’t qualify as “worked” 600’s though. Maybe Jay will see this post & comment.
