My up coming 74 w200
4.10 gears
33"s maybe 35's..
727 stock stall heavy duty torque converter..
408 dished Pistons about 9.3-1 compression..
My 596 heads with extremely low mileage
2.02's ..
Have a great set of crane roller rockers and would like a solid cam and lifters..
As smooth as possible idle, vacuum for breaks, would like power from idle to 5500... Probably running in the 22-3k most of the time...
Any other info needed let me know..
I'll probably talk to Ken at Oregon cam when I get a little closer, but some ideas would be good..
I was thinking it would be a little different than the street, strip, or drag car race cam ..
 
Also someone just said in another thread that Oregon cam updated there prices to $179...
 
Personally, I'd not use a 224* @ 050, even with a 408, for the purpose you want it to perform. I doubt you have anything close to racing in mind. I'd keep the lift around .450, the duration @ 050 around 212, and around a 112 LSA. You want bottom end grunt.

Trust me, the stroke of a 408 will eat that duration for lunch.

I have (I would have to look to be sure) something like 234-238 in the duster (I know four speed) but while not sure it would work with a tight converter it ain't over the top..

That same cam that's in the duster now was originally far over the top and would not hold an idle for longer than 20 seconds... I just took it to can and had him granted into something that could hold an idol... Resurface the lifters and everything is great now..

My Duster has 204 @ 050. I get asked all the time how the car moves out of the hole with 3.23's and stock converter.... it's because it don't have a 224 @ 050 LOL. The 408 has bottom end grunt, but the truck is heavy and the converter tight. You can get good low end or great low end, and matching components is the difference. Either way you'll be happy.

I think there is something to be said for a duration variation with running a 4-in crank.. it should be a pretty stout engine from the get-go. I did up for the forge Piston Scat rotating assembly. And it will have those 596 heads that came off the duster that were well worked over... Not heavily ported but new seats valve guides Springs retainers valves.... Roller rockers...
I love that out of the whole power and that's where the stroker itself comes in..
It'll be needed for that big truck LOL..
Like I was saying imagine it will be running around 2500 RPMs quite a bit of the time.. I don't want it running out of poo at 4K..

Looks like u need to brush up on ur tuning skill if u couldn’t make that cam hold a good idle. It should idle all day long. Kim.

like i said, either way you'll be happy. Whatever ever is in there you'll not know if the bigger cam or smaller cam would have moved your happy-meter because you'll not know the difference. Personally, I'm SHOCKED you just wouldn't call Ken. It's been your #1 cam recommendation here on FABO for the past 5 yrs...

259-267 was the old duration... 600+ lift..
My tuning abilities are just fine and it ran great.. My Time slips proved that...

The piston speed at low rpm will help with cylinder filling but displacement in and of itself has NOTHING to do with "eating" duration. That's a myth or a misnomer. J.Rob

Wow, I hear that all the time. Any cam is milder in a bigger engine. The piston is moving faster because of the longer stroke. Maybe not faster per se but it is covering more area at the same rpm/time. Kim
 
Tire size will have a factor on overall performance. maybe figure which diameter your going to use.
A 33" or 35" tire will make your 408 perform like a 360 with a 30 " tire.
