'07 Hemi Crate Motor Questions

Post by jerkyboy » Mon Jun 07, 2010 1:28 pm

My '68 Dart's prior owner swapped in an '07 Hemi crate motor. I have two questions, should the idler pulley be utilized (check out pick) and how quickly should it come down to idle when you rev it? If the car is in neutral and you rev it up, it doesn't idle down nearly as quickly as my carbureted 350 that I had in my Nova.

Try this website for a picture of the belt routing:

(Scroll down slightly on the page)

I wonder if you've got the correct belt on the engine ?

Try some of the Gen III Hemi crate motor suppliers (Bouchillon Performance ?) They've likely come across this problem before with customers as they supply almost everything you'll ever need.


As for the idle problem, I don't know. Bouchillon again ?

Beep ! Beep !
