urban legend? Heads burn up without smog pump?

I was told by my dad's race buddy that if we ran a smog motor without the smog pump, the heads would burn up? I'm not sure of that, cause lots of smog pumps were removed in the 70's and nothing happened, including my truck. Is it something specific to the smog pump and injection tubes on a 1975 460 Ford? Hope it's not the case cause we can't afford new heads right now, no matter how much power they give .......

thanks

 

Sound slike **** to me. I have trashed more than a few with no problems.

 

I've never heard that but I am a dumb cracker.

 

I've owned a (OT) Fox bodied Mustang 5.0 (OT) for 14 years now that had the smog pump taken off by the previous owner. I've never had problems with it.

 

i have taken off smog pumps and never had a problem. if i recall , the air is routed into the exhaust manifolds..nothing to do with the heads

 

Wtf?

 

It's just emissions ****. I ran my dodge 360 smog motor without a pump for years and had no trouble.

 

smog pumps put fresh air into the exhaust for catalytic converters to burn off excess ****. The thing is, smog motors are tuned to run leaner, hotter than older engines.

 

Yeah, and giant alligators live in the sewers of NYC.....the first modification I performed on my '69 SS396 was a smogpumpectomy. It idled better, it ran better....and the heads didn't burn up.

 

Maybe he has the water pump and the smog pump confused!

 

Oh you heathens! It will destroy your engine, but not the heads - the overheated exhaust wears out the muffler bearings! ;D

 

puro pedo

 

Yatsa loada ****.

I've pulled the smog pumps off every GM vehicle I've owned, including the newer L99/LT1 and never had a single problem. I'd bet 90% of the 94-96 Impala SS owners have **** canned the air pumps as soon as they could have manifold plugs fabbed. I'd bet the smog pumps that are out there on bone stock vehicles are working anyway and failed along time ago. GM even had a TSB to have the pumps removed if/when they came in because they'd lock and throw a CEL and blow the fuse to the underhood light (rumor has it that for the Impala/Caprice/Roadmaster GM hooked the air pump sensor and underhood light to the same circuit/fuse, so the GM tech could quickly identify a shot air pump as the culprit of a poor idle just by opening the hood - if the light came on the air pump is functioning - if the light didn't the air pump was shot)

s.

 

Pure BS!
I cut the belt for the pump on my 85 318 in 86; parked it in '05 with 392K on it. Body and suspension all shot but engine still runs fine.
As mentioned many older smogger engines are factory tuned lean, richen them up and advance the timing a bit.

 

yeah and if you still have the pump, it's worth some cash.

 

....along with all the stock exhaust manifolds that were canned in favor of headers, and stock four speed shifters that were replaced by a Hurst!

 

Both urban legend and rural legend!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

I have over 100k miles on mine... perhaps they let go @ 101?

 

Ive de-smogged many a motor. NEVER had one go bad.
