Eaglemark:
This isn't a stern drive (I/O) transmission. Its a velvet drive, which is a small automatic transmission that only shifts from nuetral, forward and reverse. Its a 1:1 gear ratio. I ran this engine set-up last year with a Holley 600. Idling at 850 isn't an issue when you shift into gear. I do have an exhaust riser that will except an oxygen sensor. Currently, I am tuning everything with a wideband. I understand that my VE table needs alot of work, but working on the idle was my first step.
I appreciate the feedback. When I'm done looking through your suggestions, I'll most likely have some follow-up questions.
Steveo:
This is a wet exhaust, but the O2 is in a location that does not get wet. The O2 bung passes through the water jacket, into dry exhaust chamber. The mixing of water and exhaust happens abount 12" after of the O2 bung. I'm probably going to add a narrow band for closed feedback in the future. For now, I want to get it dialed in with the wideband.
Wouldn't the IAC be beneficial when shifting from nuetral to drive and vise versa?
