Hemi Swapping a perfectly good 70 Duster

That's awesome.. Running and driving with plenty of time left to enjoy it, before it's cold again. The Hemi is definitely happy at just about any RPM. I've found that the Dart feels pretty normal, just as a daily, but when you put a foot deep in it's ***.. It's a completely different machine. I think once you get everything dialed in and wot, you should be very pleased. BIG GRIN! I can't remember what cam you went with but that may be why it feels a little less torqish off idle.. but I'm sure it makes that power elsewhere.

I had to force myself to come home with it after I realized I was out for a while and should likely go home and check stuff over. No oil or coolant drips! I may be more happy about no oil drips than the new exhaust note! Hahaha.

The good news is, the winter rarely shuts me down from driving, unless its a wet winter.

I've got the Cam Motion Titan 2 cam, which is 225/235 @ .050 and .594/.577 lift. They don't have a published PRM range, but they do recommend a 28-3500 converter (I don't that crap) and state "improved power in the midrange and upper RPM with emphasis on midrange power and torque." This is the reason I chose this cam. I felt like it would be good on the autocross. I can definitely feel it "turn on" the torque. I have a feeling I'll be bumping the rev limiter until I can train my ears again. It's so smooth I feel like I'm at a lower RPM and look down and I'm at 5500.


Side note I forgot to mention, my homemade one wire alternator modification works beautifully! $50 1 wire alternator, yes please!

Also a follow up to me being concerned about the oil pressure, Once the oil is warm, pressure is around 50 at idle. When cruising its around 70. I'm good with that!
