I have a Comp XTQ cam almost like the one Andy mentioned only with a little more lift and my car pulls like a freight train from 2000-6000 RPM

My suggestion (for that elevation) would be a single pattern cam in the low to mid-250's @.050, on a 108lsa.
Whether you use .875 or .904 lobe designs is your call.

I don't think you'll find anyone having something like that on the shelf.
The closest thing is probably the Hughes 5054.

Depending on what springs are on the heads now, it's likely you'd need to replace cam, lifters, pushrods, and springs to be able to upgrade from the mp533 cam to something like a fast rate .904 solid.

Also, if your heads don't currently have the valve spring locating step cut down, it will need to be for the springs used along with those fast rate cams.

Thank you for the info!

With 4.25" bore and even with notches you'll still run into exhaust valve to wall clearance issues the higher the lift over .520" it gets very tight in a hurry. Probably your mid lift numbers will be lots good enough to make good power without using a high lift cam. I run both Stock Eliminator and SuperStock max wedges.

If the high lift lobes create an issue with valve to block clearance, then you'll likely end up having to have something custom done if you want to have the desired duration and lsa, and still end up with .520 net lift or less.

Well since it once had a MP 590 in it, before the MP 533 I'm sure that would fit again, if all else was the same. Wouldn't be a bad choice at all IMO I like the 106 LSA for your engine combo. Install it around a 100 ICL

If you want something more modern, maybe a hughes 6872 It has less intake duration, 268 @ .050 compared to 271 @ .050 that the MP 590 has, but more lift .629 But with your heads the Extra duration of the MP 590 and 106 LSA, might be the actual better canidate then the more modern cam Hughes. Some will say, Roller all the way. Not a bad choice either.

Try Comp's #23-472-8 (may have changed last number to 9). It is a solid roller with .575 gross lift. It has 262 duration @.050, ground on 110 lobe separation. It installs at a suggested 106 center line. We've run this cam in multiple motors, and every car was at least 3600# as raced.

In our 440 with modified 452 heads (2.14 x 1.81 valves) and at 13:1 compression, it went 11.17 @ 121.5 MPH. The MPH tells me that it had much more in it as for ET. It was run on M and H street slicks.

In the new 496" motor with Stealth heads. This combo has only been down the track on one visit, and ran an 11.62 @115 best. There were some issues that needed attention, and I know it will run mid-to-low 11's as is. It's very streetable, and works great with more compression. Good luck whatever you decide. Love '62 Dodges!!

Thanks again for the info!

I'll update this when I stuff a cam in it, and let you guys know how she does.

BEAUTIFUL!

i REALLY like the looks of your car ! at one time i had hoped i could do a 62 dart post before i croaked, but it isn't in the cards. yours, however, allows me to at least dream about what could have been !

What a beauty!
