super ram install
In process of install of SR on 89 with accel intake.I'm confused about cold start block off.Reading accell ads they claim you need block off only for 85-88.I just recieved accell block off kit from summitt and do not see how this will work. Plugs it came with are too large for cold start hole in SR runner. they claim it is right part. Any help much appreciated

Check to see if the plug fits into the end of the drivers side fuel rail.
The cold start injector is in the intake manifold only. If you were using the intake with stock runners and plenum you could use the cold start injector or block it off. Once you add the SR runners, they block the cold start injector (CSI). You should not need a block off. You will need a plug that fits into the rear of the drivers side fuel rail if up deleat the CSI. The CSI has a steel tube that comes off the rear of this rail to the injector.
Pre-assemble the SR and runners. If you are also including the intake manifold, bolt up the runners to the manifold and check for bolt clearances to runners and that the bolts are not too long. Cut down bolts or grind them down if you find that some are too long. At this point you will find that there is NO room to get the little bolts they want you to use to bolt the runners to the base of the plenum. The rep I talked to at Accel suggested throwing the bolts away and replacing with studs and nuts that have "star" washers attached. This will be easier to install, not perfect but better than the bolts.

I was not satisfied with the plug I bought from the detail zone to block off the CSI port in my SR runners.
Early SR runners did have provisions for the CSI, contrary to popular belief.
The hole itself was roughly machined in the runner and the plug didn't fit well at all. It sounds as if the Accel plug isn't much better.
Instead of using the aluminum plug, I simply filled the hole with some FastSteel reinforced epoxy and made sure the mating surface was smooth.
I can also recommend using studs on the plenum and kep-nuts or k-locks from below the runners. Works like a charm. If you run a search you should be able to find one of my old threads that references the stud part numbers available from Auveco.

Got pics ?? I accidently bought the wrong part when I had to block off the CSV fuel line from rail. I ended up with an aluminum plug for the CSV port. I believe it is used with an O ring and bolt/washer to hold it in port.
