Cam for torque question

-
SER3438ALN10.jpg


Latest cam recommendation from Hughes. I'm changing direction. This one is a hydraulic roller...I wish it listed the advertised duration.

This is a long snout cam. It works fine in the 93-03 Magnum engine but you will need to use our HUG7011 Cam bolt & washer and the HUG7542 cam key (see below in Related Parts).

Hydraulic roller small block camshaft.

Basic guidelines (These are not absolutes, just guidelines to help you get close on a cam choice)
Use: Serious Street or mostly Strip, works well with aftermarket heads and high flow throttle body/carb, upgraded injectors a/r
Idle: Noticeable
Vacuum: low to mid
Converter: 3200+ stall
Rear gear: 3.55 +
Benefits:510+HP potentiel at flywheel
Requires a computer upgrade (like a tuner)

Here it is....the 408's finally done

Mahle forged pistons sit in the hole .010 (hope I didn't screw up the quench), .027 mls gasket, 59cc closed chambers, 10:1 comp, Indy IMM heads, scat forged bottom end with Ibeams, and the above Hughes roller cam, rockers and retro roller lifters. Keeping my fingers crossed on the roller lifters....lots a horror stories out there. Don't really like the angle the push rods enter the lifter at either...pretty steep...seems like an opportunity for a bunch of side load. .060 shims on the rocker shaft to get a centered wipe...more than a 16th less than an 8th...3/32...nice. Should be close to 500 hp...we'll see what it does on the chassis dyno soon.

I have the those roller lifters, have been in my car, going on 3 years now. Have turned them over 6500 before with no issue. but normally shift at 5800 rpm. running a little bit more lift and duration then you.
No complaints!!!!!
 
Oh that's gonna be nice!
What rocker ratio?
 
That's goning tobe a nioce ride with the 3.55's. I need the same gear set for the wifes ride.

Is that the engine you found on CL?

Yes, the only thing I used was the block, timing cover and oil filter mount. It's internally balanced so I'm gonna use the 318 stall(2200) and the 318 flex plate.
Edit: I can pickup an A999 lockup and another 904 for cheap... the existing 904 is still in the car. will the internal 999 parts work in the 904? I thought I read somewhere that parts interchange like the 5 clutch pack and the 4 gear planetaries and a lower first gear??? Or do I have only part of the story???

Not sure on the tranny stuff but I'm glad the CL purchase worked out for you.
 
I run that exact cam in my 340, and it is an AWESOME cam with a nice (but lopey) idle and plenty of vacuum for power brakes. The valve train noise is NOT a problem with the cam.
