Thanks. The Duster has a 372” W2 and the Dart has a Ritter block 436” with W5. The 436 is still new with about 20 passes on it but at 20psi it has been 8.0 at 176 at Vegas which is 2000 foot altitude. The Gen 3 Hemi is really good. I have a few buddies doing well with their combos. As far as the Holley install goes, here is some unsolicited advice. Run big battery cable from the battery to your heads and block. I spent a year trying to figure what my problem was. Turned out the Holley is very sensitive to EMI noise.
