Thanks for the video. Does the 2007 model have the same block water drain system? That drains the raw water, yes?

@christopheraust give us a call with your engine serial # so we can look it up. 1-877-666-8679 -phil

Mine has been overheating at idle, yes of course it was in water. Any suggestions?

[michiganmotorz2008]

@coltybaby1587 Check your impeller

[psb116]

Does the same engine with Bravo III configuration also have the shift interrupt switch?

[michiganmotorz2008]

@psb116 yes but not the same style that is used on the alpha

[CRT193]

what does the shift interrupt switch do?

[michiganmotorz2008]

@CRT193 retards the timing, to enable smooth shifting.

[deepfriedmeatpie]

so smooth

Im assuming its a chevy vortec engine right?

[michiganmotorz2008]

@sms373 Correct Chevy Vortec
