I am going to be installing the sniper EFI and I am wondering what folks are using for the base gasket? I am running the performer RPM intake manifold. Any help is appreciated.

Squarebore? If so, use the gasket included in the kit, or order the thicker Mr. Gasket gasket.

I believe it is spreadbore, there is a divider in the center? I thought all of the edelbrock performer rpm manifold were the same and it seems alot of people run them is why I thought Id post the question here, thanks for the reply I will check out that forum as well!

I

I was referring to your Sniper, they are either Spreadbore or Squarebore..

I have always used the gasket that comes with the SNIPER unit.....and they have worked fine for my applications......

akspeedy

oh gotcha yes I bought I believe the first set up it is sniper 4 bbl it’s not the 4150 stealth and it’s not the qjet and it says will work with either I believe it comes with the square bore gasket thanks for the responses

akspeedy

thanks yes it comes with square bore gasket I just didn’t know if that was correct I believe my performer rpm is spreadbore and didn’t know if a different gasket or modifications were needed thanks

If your performer RPM is a spread bore you might have to use the 2732 thin "adapter" plate to prevent a vacuum leak.

akspeedy

Correct, I have been told to use the edelbrock 9265 insulator gasket in place of the 2732 and should have no issues, we will see, I’m in the process of rewiring with an auto wire harness so it may take me a few days to be ready to run! Thanks for the replies

Are you putting this on the 83 H/O?

akspeedy

NO! I am building the 350 from my 72 convertible, it will be nice to see how reliable and affective it is I would not be opposed to putting it on my 83 at a later time
