So the air pump really doesn't do any real cleanup, just dilutes it ? Kinda like peeing in a ice cream pail vs peeing in a pool.

It was claimed to create an "afterburner effect" and the high temps would burn off the "unburnt" fuel... Yeah, right!

At least the PCV system would give you visible results. And for the better too! I'm old enough to remember cars with the road draft tube and smelling the fumes from the motor while waiting at a light.. no thanks, I'll run a pcv and enjoy breathing.

Everything I have besides my F350 has a road draft tube. Well except my 72 and Vette. They have catch cans now. Haha

I must disagree with 34-40 I was in the emissioms business sence the norris thermadore pcv law thats when I got my first licence in 1962 when we blocked the road draft tube and installed a primitive pcv valve and taught emissions for yesrs the purpose of air injector sys. is to add o2 down stream to continue to burn the unburned ( hc) hydrocarbons later years the added catalitic converters think of thoes as after burners they need o2 to work if you turn off the down stream o2 it won't be long before you plug op the cat. and you will have major drivabilty problems thanks to the advent of the onboard computer we have come to the point that we can controll the a/f mixture and timing so precise we can have cars that perform, get great fuel miliage, and are clean the newer cars when you put them on the infred red emissions tester they come up what we call owl eyes 00-hc 00-co- 00-o2 the air going in the intake is dirtier than that comes out the tail pipe

And I will disagree with you when it comes to the early systems, they were JUNK, pure unadulterated JUNK.
When I came back from overseas in 64 my dad had bought me a pristine 57 Ford Custom that he found at the dealer up around La Habra where he bought his brand new T-bird. Since it came from a dealer it had to be smogged with a primitive pcv system that plugged the road draft tube amongst other things. I came home in June and a couple of months later I was heading back to Anaheim from dropping a buddy off in Santa Fe Springs when all of a sudden there was a large bang under the hood and close to two quarts of oil on the right side of the windshield and the rest of the car. I pulled into a gas station down the block and discovered that the crankcase pressure had been so great that it blew the dipsitck out of it's tube, denting the hood and blowing the oil on the windshield. I put 2 quarts of oil in the engine and the next morning when I pulled the rubber cork out of the road draft tube I made one hell of a mess on my dad's driveway. I put a vented cap back on the oil filler tube a shit canned the pcv valve and plugged the hoses but the damaged had been done to the bearings. What a waste and if pcv systems are so great then why do you still have smog in so. california?

Ken you are right about the norris thermadore sys it was junk and we had alot of customer complaints about them but it was a start. 2 yrs. later they were improved on buy detroit and and became std equiptment and yet some people even took thoes off. They actually help the eng and performance how dumb is that. I have seen the auto industry and hot rod qualty really evolve in the last 60 plus yrs.

So have I ,but you didn't answer my question. Why do you still have smog in so california?

I think that California has made great improvements in their smog situation over the years...I am not a
big fan of pollution controls on motors but in 1971 you couldn't see a car cross the finish line when you
were standing at the starting line at the drag strip in Pomona. Now, you can see completely across the
parking lot....mucho better. Of course, now there are many times more cars AND not all pollution is
from cars. I think they are at the point of diminishing returns now, the easy stuff has been fixed.

I remember that well, I left in Sept of 72. The real problem was diesels and factory emissions and the fact that the LA basin is sided to the north, east and somewhat to the south by mountains and the ocean to the west. When the tides come in it bring along with it heavy moisture laden air which head east only to bounce off the mountains and head back west over the basin and thus you have smog in the basin. At one time there were more, maybe still is, more OTR trucks registered in california than any other state with NO emission controls and therein was/is the problem. They've run all of the industry off so they can't be blamed anymore and they finally required emission controls on diesel engines, why do you think Mercedes quit selling diesel cars for a few years? And have you ever been behind a bus in the LA area in the 60's? You needed a gas mask if you had to follow the thing very far. California is only progressive when it comes to spending other peoples money, other wise it's full of fruits, nuts and stupid liberals.

Commercial wise you can't even have a truck in CA older than 1997 and if you do they fine you even though it doesn't say that on their site or regulations. Diesel has came along way in the last 15 years for sure. The air coming into the air filter is dirtier than the air coming out. That's about the only positive about it if you own any or have to work on them, that is another story.

That's route I took on the Healey. Easy to disassemble for service too.

I checked out he 350 Vortec today and I'm going with that motor. Engine oil was full and clean and the radiator was full on antifreeze so those were a couple good signs. If I sell a few parts off the pickup and bring the rest for scrap, the motor will be free.I slowed this whole project down a bit so I can decide whether to just freshen this up with rings and bearings and a cam or if I want to build a 383 ( I've wanted one of them since I was 16 ) I guess what it comes down to is which Camaro I want to be the quickest

( in my best Yiddish impersonation) such a problem to have!

Every time I watch Street Outlaws and see Monza's car, I get stupid ideas and more drive to try to find another.

Well, I tripped over Votec 350 #2 today, this one has 125K and he wanted $200 for it and that includes a new set of shorty headers.Their kinda worthless for anything I got but free is free. I hope its as good as he said it is cause I'm going to do a bearing check and swap the cam and intake, and that's it. I'm going to try to keep this a budget build under $3500 including the price of the car. Right now I'm sitting at 2550 and that price includes billing myself $350 for not selling the 700R4 that I have laying around.I think the exhaust on these stupid gen 3 Camaros is going to be the budget killer. I'm just about certain the other 350 is going to be turned into a 383 and be jacked up a bit more for the 71 when the time comes.

I was thinking more like this Ryan, It's hard to find a pic without that aftermarket cowl hood.
