What size thread is the pipe on the back of the motor. I believe it connects to the air pump. It connects the the back of the cylinder heads. Most of my emission stuff is gone. When I put the new engine in, the air pump seized up and I just re-moved it. I capped off that pipe, but the cap fell off and now it sounds like crap. So I need to redo it again

anyone get that thread size?

i dont have the time to wait for ryan to ship em, so i need to head to home depot to get some pipe caps for the back of the heads,

FYI: my emissions equip. failed along time ago so it was removed and since i had GT40 heads with NO ports i didnt need it anyway, now i have been forced to put the E7's back on and NEED to cap the ports since i dont have any kind of emissions equipment on except for the EGR, i kept the EGR

need the thread size

any help?

There's two holes. Ones the port, the other is where the bolt goes in to hole the crossover tube on. Buy the cover plates and use the 5/16 bolt like I said.

So no FAIL.....:haha

I don't think you can turn it around backwards due to the check vavle might hit the intake :shrug But you could cut and weld the ends shut.
