Yet another Belt Size Question...??

[PA SNAKE]

Yes, I already checked Cobra Bob's belt sheet and my configuration wasn't on there.

I bought the car with a Metco 6lb lower, a Metco Idler pully that attaches to the Metco bracket and a 3.5 Alt. pulley. The problem is the Metco Idler pulley (not sure what size it is, but its really small) the bearing is shot... making all kinds of noise, has alot of movement, etc.. So I purchase the BilletFlow 3 piece Idle (3x100). I'm going to pick up the other 92mm when I change out the blower but for now I have to get the car on the road again.

My configuration that I'm trying to size the belt for is this:
- Blower Pulley (Stock) 3.65
- No Snub idler, I will add this when I do the blower swap
- Alt. Pulley Metco 3.5
- 3 x 100mm BilletFlow Idlers
- Crank Pulley Metco 6lb Lower

If anyone is runing this configuraiton or has any guidence, it would be greatly appriciated...

Thank you, Rick

TTT... after more research, I think the Metco idler that I'm having problems with is a 90mm... so I ask this question, can I safely assume that if I replace the 90mm with a 100mm that I can measure the difference of the two and and that to the overall belt lenth...?
