I borrowed Bill Pickering's Renegade HB and notice differences with my old Jaide sourced HB...
The shaft collar is taller on the Jaide. I thought these were "standard" GM 6 cyl HB's. (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) The Renegade HB (even with the spacer) will actually "work" without modification since I lost .25" with a Milodon timing gear drive. (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif) The whole issue is alignment with the alt and water pump pulleys. Question 1, are the taller collared HB's still available and is any other converter using them? I know DH has a set of spacers behind the HB. Question 2, What is the clearance between inner HB surface to engine block? Seems the Renegade is mounted pretty close to the block... Attached image(s) |

I've always questioned using that HB that is designed and built for a low reving 6cyl. engine on the V8 (didn't use it on mine)
Think about it spinning at 6/7k RPM 5 inches from your butt. All of the drag race sanctioning bodys make you use a SFI approved aftermarket harmonic balancer on any car that runs 13 seconds or faster in the 1/4 mile. Bob |
