Performers are higher rise and have slightly higher torque points. the performer is 4"+'s tall the weiand is like 3 1/2. I would change the old springs, and seals on the old stock head.

That makes me happy, because a performer is what I've got Seals will be replaced as part of the entire gasket kit I'll be purchasing from summit/440source. Haven't decided on that one yet.

In a 400 it had good topend but no low end guts. I prefer PAW cam 22942- Pawengineparts dot com... It has 204/214@.050/.420/.443 lift. It was a great truck cam in my 85 3/4 ton. Better mileage by far than 6401 and much more low rpm power. I think it would work good in a low compression 440. The PAW cams are cheap and good quality. I always use their lifters and valve springs also. I would use that cam with an Iron spread bore intake, a 1/2" spread bore to square hole adapter and a Holley 600 or a 750 #3310. 5570885-P71001.JPG (76 downloads)

For a 2wd street bruizer of a truck, the whiplash seems like it'd be a good choice. For an off-roader a milder cam is good. Pat, I'm going to say your stock valve springs are probably going to be okay. This cam is similar in spec to the stock HP cam, and the HP 440's did get different valve springs than stock. However the lift is low and duration is mild. You're not going to get crazy high rpms out of it.

I have used it with stock valve springs. If you decide to use the Summit cam #6400 then make sure you have the high stall torque converter(fat ring gear). The PAW cam is rated 1500-4000 RPM. The Summit cam #6400 is 2000-4500 RPM. I guess the choice depends on what RPM range you do most of your driving 5570996-Const1017.JPG (58 downloads)

Pulls good vacume, idles smooth, and it's very responsive. Why buy a stock mopar cam grind when there are cams with more modern designs that will perform better? Get something with a wide lobe seperation angle to keep the idle smooth.

My only reservations are not knowing if my stock valve springs can hold up to it, and not knowing what stall converter I'm running to make sure it's appropriate. I did take a look at the PAW cam. Seems fairly close in relation to the summit cam. Like I said, without sacrificing drivability, vacuum, and lifespan, would the summit produce the same amount of power just at a slightly higher RPM? I do a lot of highway driving, so I wouldn't mind the 2000-4500 rpm range, but I'd also like to be able to get moving from stop light to stop light, if you know what I mean.

Get something with a wide lobe seperation angle to keep the idle smooth. The mopar cams (even the old ones) have pretty fast lift rates. Compare advertised vs .050 duration numbers with other cheap cams and you'll see the mopar cams have bigger .050 numbers for a given advertised number. The resto cam also has a 115deg lsa, so it should idle like...well kinda stock Travis.. 70 GTX project, orig 440-4, 4 spd, track pack, FC7, stripper/street racer special.

Could barely tell it had any lope to it, ran out of breath at 5k, but would melt the right tire off even with the 2.76's from a dead punch.
