valve springs - recommendations
hi Folks... Looks like i´m a bit fucked up now...
as i mentioned above...the stock cam out of the 5.2 is trash... so i took an other used cam, which was offered my from a shop here in Germany for about 100 euros.
now as i have this in my hands, i just took measurements as the shop-owner told me he didn´t have any specs of this cam but it should have somewhat about 0.460 lift.
okay ..if so..it would be not the hottest one but a Little more lift than stock (0.432 lift)
it turned out that the cam i got from the shop, came out of the 300hp 5.9 Magnum, as i measured somewhat around 0.390 lift for Intake and a bit over 0.400 for Exhaust
refering to Ma Mopar it should read 0.387 and 0.401 for the 300 HP cam.
questions is now what to do...
spending more Money an get a
- custom grind (ouch... not easy to manage from Germany)
- one from Lunati or CompCams or Hughes
- or one of those Whiplash-Sticks
3,91 Gears
26.1 Inch Tall Tires

Car is a blast, streetable and driven 50 miles to the track. With cooler weather coming down south, a little more tweaking, and better driving on my part it will only get quicker.
Weather was 55* and low humidity last night, car ran 11.946 @111.66
60' 1.644
1/8 7.564 @90.02
Actually weighed the car and it's 3360 full fuel with driver.
99% sure my carb is dialed in. Still tweaking pump shot cams and nozzles.
I cross the line at 5500 RPM motor still pulling, so I'm gonna try some 26" Hoosier QTPs and see if they let the motor RPM a little more at the stripe.
