'05 Hemi ?'s

If it’s a budget cam and heads will blow it away. That is a low low mileage motor. Mine is bone stock. With 6.1 intake mainly for looks. Had to buy expensive spacers and alternator and compressor brackets to move them out more for the throttle body clearance. If I had to do it again I would have stayed stock just to save money. The intake was given to me. I drive mine across the country, highways and rush hour traffic in 100+ weather. If it’s for cruising and occasional track I personally think you won’t have any problems. A friend has a 62 Plymouth with the 5.7 05’ and he has clocked over 120k on his used motor. I drive this thing like it was stolen every time I get in it. I don’t need more power it has plenty for me. Thats my 2cents.
