Wonder if the "Umbrella" style of them causes a low pressure area to draw additional fuel?

This brings back a fond memory from over forty years ago. My buddys smallblock front engine dragster had a worse bog than yours . The motor would die. So we opened the garage door, ( for safety of course!) , i drilled the shooters, and Mel my buddy held the hand brake and tried it. Died again, but hic upped a little. Drilled shooters more. Second try, better, but died. Third drilling, that thing lit up and was in the street instantly!

They still pull fuel on the dyno...Just saw it.

This is how you don't waste limited time at the track, nice work!

In an effort to eliminate a lean bog, I ordered BLP '35' squirters. They are machined billet alum. and I wondered if they are interchangeable with my swap-meet proform 750 bodies. They look radically different but the critical heights suggest they'll work. So these have 4 release passages versus the 2 you'd have normally with a conventional holley squirter. '35' means .035" per orifice so, these have smaller orifices to achieve the same volume (and no, i didn't bother to measure them) After I bolted 2 on, I thought it may be smart to run a reamer thru the orifices 'just in-case'. That was a good decision because half of the machined orifices had burrs. Regardless, it's likely a quality product/improvement and I'll be using them.

Just pinned mine. The orifices are about .024". A .024" fit easy and a .025" wont quite fit, so maybe .0245" on a .035" squirter?

I was just going to ask if a "35" 4-hole design meant each pair was actually .0175" per hole. Starting to sound a bit arbitrary as to how they label the sizes, since what you described I'd call a "48", not a "35".

maybe we bought the wrong size and they have a method of sizing to get the same flow as the old school squirter? I will talk to Dom about this, but i'm sure he said he bought .035's and they work real nice.
