AHA , He's Not Aftyer a OS Needle , nercosarilly .
Some ST ones Center , But are a tight shove .
The real OS ones are pretty rare .
The OS Max 40 S & FSR 40 , along with Max C 35 intakes match .
mEASURE aCROSS THE INTAKE , TAKE HALF , AND SPECIFY
for ' flange to hole ' , on a aero products or similar .
ps might be the Merco NVAs that are a mighty tight squeeze .
Custom , Mr Hunt & colleges went for from .275 to .318 Venturies , for the FSR 40s . typically .285 to .310.
with .318 for his Xe 12x5W 11 in three blade at the 78? World Chumps .
If you trip over a pile of the Factory intakes , the FSR are taller than the 60s/70s Max S , Lemme know .
They can be whittled / honed out from there .280 / 265 . Came in Two Bores , in the long & short ones .
A lotta dudes use a ' sealing ' washer Ea Side on a spray Bar - so that gives you some leeway .
Incidently , What muffler do you run . And What aeroplane . Not many FSR s running in P A these days .
Ive Gotta Genuwine 40FSR-S & a bitsa Magnum / OS 45 . Spare Sleeve/Piston assys'd be handy .
The Royal 45 Clone has earliest closing on the Shaft , so likely best option .
Where Were We . . . NEEDLE VALVES !
