Great street engine Brent.
What's the apx cost ?

[blykins]

That one was $12480.

Brent,

If you may; can you discuss why Quickfuel 750, instead of an 850 cfm carb on that particular combo?

Thanks!

[blykins]

If someone wants a brand new carburetor, Quick Fuel is my choice. 

The HR series can be had in both mechanical and vacuum secondaries and with a choke, which matches the degree of streetability that some guys want. 

Used Holleys can be rebuilt cheaply.

This looks like a driver, I'd suspect the 750 is just as good as an 850 in the under street rpm range.

Having owned both of each, I have to say, old Holley's are nice, but the new features of QF carbs and the quality of the metal used makes them much more fun to work with.  I don't think I'd ever buy a new carb that wasn't a QF.

Cool. Thanks! Though 525/588 is awful nice "street" for this combo.

Brent do you have a graph of this one?
I'm having trouble getting near 588 ftlb out of the Gonkulator.
Was it 10.0 CR or maybe higher?

[blykins]

It was 10:1.

However, the peak torque could have been the way the dyno was loaded or something similar. 

I do know that the owner put it on a chassis dyno to tune it in CA and it put down over 500 lb-ft to the tires, going through a TKO 600 and a 9" Ford. 

But dynos are dynos are dynos.....................................I really don't pay attention to any of them anymore unless it's multiple engines on the same dyno, where you can see what was done incrementally, etc.
