Absolutely no problem Frank. We have 11 second street cars using the original pump and the original fuel line, believe it or not. The problem with the original pump is the high pressure and in most cases you will have to use a regulator. Or you can do it the hard way, shim it out to you have the pressure you want. Sorry, no pictures.

Ran my 1776 with 48s and a stock pump. BB is right though, you need to drop the pressure down either with a regulator or shimming the pump.

I ran my 2332 cc with IDA's for several years on stock fuel line and stock-style pump until last year (photo below).  I switched to a Carter rotary pump last year, with no improvement...still running high-12's in the 1/4-mile at 106 MPH (170 KM/H).  I'm going to try 9.5 mm (3/8") fuel lines next:

I ran a stock fuel pump and line with IDA's on my '63 last year. It ran fine on the street but would run out of gas at the track right at about the 1000 foot mark. I upgraded to a holley red and 1/2 inch line last week. I'm taking it to the track on Friday to find out if it helped.

2180 with dual IDAs and stock pump.

I can tell you there is a limit to the volume of fuel it can supply. From a rolling start with my foot to the floor, shifting at 6500rpm the carbs run dry at 105mph, that's about 5000 rpm in 5th gear (0.82 5th and 3.875 r/p).

It's fine for street but if you plan to race you need a electric pump.

How about an electric pump but the standard metal line through the tunnel. Would that be OK  for a 2276 with 45's?
Thanks

On my 2110 with stock pump 48 IDa's - K10 cam etc....My results are the same as Glenn's. On sustained high speed runs (100 + mph) I had fuel supply problems. On the street - light to light and cruising no problem. You can do short bursts but I don't think you can do long high rpm / power situations.

It fits, might need slight filing depending on the manufacturer of the pump.

It depends on which "stock fuel pump" you have.  Some of the common ones which have a side exit fuel line will interfere with the MSD.  I swapped to a Brosal OEM style with the top (vertical) exit fuel line and all was well...see my photo above.

I've been told that the stock pump can be used to about 175hp. After that you need a electric due to the higher volume.

I run stock fuel pump with 48's, fuel pump shimmed to correct pressure of course.  My car is mainly a street car, and I strive to keep the mods to the early 70s timeframe, that's a lot of the fun of having one of these cars IMHO.

If more race, I'd go electric.
