Re: Where to get vacume off 250 i-6
Should be a plugged port right below the carb on the intake plenum for that.

Yup. Soak it with PB Blaster or your favorite penetrant for a day beforehand. Get a 1/4" NPT barb for the hose to connect to.

Re: Where to get vacume off 250 i-6
I think I know the one your referring to. on mine its in the manifold between carb base and valve cover side of intake correct ? thanks fellas. one last thing is the master cylinder cardone #10-1511 for manuel brakes the same m/c as power brakes ?

Re: Where to get vacume off 250 i-6
found it guys. bet this is gonna be a bugger to get out ! also looks like a 90 or 45 degree barb fitting will be needed. are the booster and m/c different for 71 & up trucks compared to 1970 drum brake trucks ?

A little propane torch should work. Don't get lazy and think you can tee into the pcv line. The booster needs it's own vac source. If you need a factory looking fitting to hook your vac line to, look here. https://www.paragoncorvette.com/c-22...aspx?pagenum=1 |

Re: Where to get vacume off 250 i-6
Mine wasn't hard to get out. Sprayed PB on it for a few days and it threaded right out. Used a straight barb...a 90 might've worked too but I didn't feel it was necessary.

Now, I need to get out the rust penetrant and soak that up. I have already soaked the front end with penetrant, which hopefully makes it easier to remove most hardware. Bill |

Also, if you want the correct air cleaner for power brakes this is what you're looking for.

Re: Where to get vacume off 250 i-6
well I looked at my 70 and the plug for vac isn't even corroded plus I looked thru my 250 engines and found the original vac line fitting,lucky me I recon. but while looking at the engine in my truck there definatly isn't room for a brake booster with the air filter mounted on top of the carb so now I,ve got to hunt down a p/b air filter. my engine has a Rochester mono jet carb.
