Well, I'm going to upgrade one of the neglected old gals (non-CDL dump)-- 85 F-600 370 2V (Eaton Two-Speed Rear, NP 4-sp) with all the plumbing (EGR, EVAP, Thermac Pump, Charcoal Canisters, vacuum amplifier, associated solenoids and vacuum lines). New setup I have in mind: ~600 CFM Holley w/manifold. Truck is not tagged, not subject to emissions testing--- simply does loads / runs around the farm, occasionally locally to farm supply locations.
I'm trashing all the emissions mentioned above and don't expect any change -- fab'ing new bracket / belt tightener (Milla Time) in replace of Air Pump so one of the hydraulics pumps can remain "alive and cooking".
Anyone have relevant experiences with the aforementioned emissions deletes and move from ~350 CFM to 600? (when I ran the numbers it appears the existing mech pump and sizing/ short runs (6AN) to the fuels tanks are "ok" for now with that relatively low CFM Holley)
BTW -- seen loads of complaints about Ford Medium Duty's, but these things do a day's work, don't ask for much in return. The Eaton, Spicer, etc components are excellent examples of US quality

Reason: Remove political comment.
Why pull the evap? You will need to rig a vent system that doesn't gas you out in the cab and doesn't feed fumes to the engine compartment.
I'm not a fan of EVAP deletes, but have done my share and most (unfortunately) because of obsolete / unavailable parts. Such is the case here with solenoids, vac amplifiers that just aren't avail anymore.
As for these older EVAP systems and "fumes" --- they VENT fumes to the atmosphere ALL THE TIME ANYHOW --- especially :
-- when the vapor exceeds the canister's capacity
-- when ambient temps get high (>90)
-- when the vehicle sits for extended period and the can purges itself (to atmosphere) --- happens more than most realize
EVAP (notably the older ones) are full of problems -- I'd be the last person to defend their operation................
Rather than running a hydraulic pump full time (not a good idea) look into a set up using a electric clutch similar to a AC compressor clutch to turn the hydraulic pump off and on.

Agree -- that Lucas Girling arrangement isn't the greatest.........parts not readily avail these days either.
Going with an old 429 intake and a rebuilt 600 Holley that I had in used parts / junk bins and will tweek the Holley slightly-- ditching the governor too. Small investment to add a little to a otherwise underwhelming engine, but these darn trucks still do a decent day's work and cost very little. I only paid $500 for the vehicle to begin with...........added a new $50 motor to the two-speed rear controller, rebuilt the 370 (they're fairly stout), replaced piece parts on the Lucas Girling, etc --- may have $2000 (largest junk was machine shop work) in the vehicle total and it earns its keep every year by hauling farm material. Don't want to overload the old gal (14' dump bed, non-CDL) because there are definitely limits to the 370.

I was referring to a hydraulic pump to operate accessaries like a dump bed or spreader bed.
I got away from juice brakes on anything bigger than my F-450 years ago, air brakes are the only way to go on big trucks, my F-800 has 8.3 Cummins with air brakes.
Howdy, if your "old 429 intake" is aftermarket aluminum, be sure & check clearance between the #1 intake runner & the dual thermostat housing. The Edelbrock performer460 is perfect fit.
I don't know if your 85 F600 has the same t-stat housing as my 79...may be a non issue.
I had the heads fully rebuilt last year, replaced the cracked exhaust manifolds with Sanderson block hugger headers (these are a close match dimensionally to the stock manifolds) made for the last years of the lightduty 460 trucks. The headers required swapping to the late model 460 starter as well. A custom 2.5" into 3" Y-pipe, 3" magnaflow muffler & thats it for my 370 upgrades.
At some point in the trucks life a PO had converted this 370 4V to an Impco LP setup.
good luck with your project
Thank you!! (good thing I actually looked under the hood to see that nutty T-Stat Housing)
