RE: amazing stuff
the first holley i owned came off a 351w e-150 van that had just been junked. it was the original carb, i bolted it on and drove away.
and yes, mathmatically a 600 is too big for a 289/302 but again, in reality your driving on the front two barrels 90% of the time so its flowing closer to 300 cfm.
really if you want it all there a good route to go would be a 500cfm 2 barrel. holley makes em, and i was once told the big block fords with 3 barrels were autolite 500cfm units. food for thought

Three different guys who are not on this board and whose opinions I respect told me that 450-500 cfm is the biggest flow you would want to go on a 289 with no mods other than intake and exhaust. So, that's what I'm planning on. I still need to decide between a Holley and Edelbrock, but I've got plenty of time before I get to that point, especially at the rate I'm moving on the car (sometimes I wonder ifI'm not movingbackwards
).

RE: amazing stuff
i still disagree on the size even though mathmatically the numbers are low, look at some of the carbs ford used back in the day on small blocks.... hell wasnt shelby using 780's on some of em?
remember, unless every time you push on the gas pedal you are going WOT, or have a mechanical secondary double pumper - your only driving on the front two barrels and MAYBE when crusing the secondaries are slightly opened
if your gonna go small, http://www.holley.com/0-4412C.asp FTW

I agree. A 4V carb is just a small 2V until the secondaries flow. This is why they improve torque.
Holleys are dangerous leaking junk that should not be used on any car of value operated on the street.
There were no less than 12 of em in my shed that were set out by the street one morning.
The original postee would benifit from a new Edel carb or a rebuild of the old one.
