Hi everyone, I'm new here so please bear with me.
I have a 86 Blazer 305 with wierd options that I got in 94 replaced the U joints in the front 3 times but now I need to replace the head gaskets and the thing is covered in hoses and wires and is beyond my skills at rebuilding engines.
How much of this junk can I get rid of so I can get the heads off and do what needs doing
Or maybe how do I do it?

Thanks in advance

 

My suggestion? Have a shop do it as you stated it is beyond your skills. Removing/deleting "pollution stuff" can lead to quite a hefty fine, not to mention undesirable affects upon engine performance/reliability/operation/etc.

 

Boy did I ever word that one wrong!
I am sorry but what I meant was that the PC stuff was beyond my engine rebuilding skills, I've been rebuilding engines since I was a kid.
Somehow it turned out that this is the 1st. time that I've ever had to deal with this stuff.
All an engine needs to run is gas and spark.
So the question is: how to I get back to the basics?
This stuff does not effect the laws were I live, as for engine performance/reliability, it would be nice if I could get those to the high standards that I'm use to. A 305 in a light weight Blazer should get a lot more than 16 miles to the gallon!

 

my 305 in my 1990 2wd silverado runs really good and i only get 14mpg and i figured that was plenty good. so if youre getting 16 in a carb'ed 305 thats pretty amazing in my book, my k30 gets 7mpg lol

you can pretty much rip everything out of there, just need a vacuum line for the booster and the distributor. only thing im not too sure on is if you have one of those carburetors with the electrical connections and a bunch of vacuum lines going to it.

i got a 86 k30 but its got a 1973 engine in it, nothing but the bare minimum in this thing.

if you dont have the electrical carb and just a normal aftermarket one just google pictures of 70s 350s and you can pretty much see theres nothing to them

 

I have no idea about this so I'm uploading a pic link.
It looks like 3 wires but a mess of vacuum lines.
Too much?
Thanks
