428cj cam&intake suggestions

[3pgnebs]

Freshening up a 428cj in a customer's 67 GT500 clone and he is wanting to pep it up a little from current specs.  Motor was built about 14 years ago by a mustang shop in ATL, using TRW forged pistons, B&B, Edel 427F manifold, & a Melling hyd camshaft specs: 514 lift both sides with 300 Int(misprint on supplied paperwork?), 224 exh.  Intending on installing a updated camshaft definitely, possibly a intake also?  Block or heads one were decked and the current manifold was cut, and don't know if the customer will want to spend the money to cut a new intake.  This is a weekend car show/cruise-in motor, want be drag racing I'm pretty sure, just wanting some more pep in its step.  Needs to be a hydraulic, off the shelf.  Intake suggestions welcomed also.

Thanks,
Brian

4 speed or auto?
Rear gear?
As for milled heads and intake, unless the heads are real 67 GT heads (and I mean that sarcastically)
for mild pep most FE heads are not that bad. And the 427 Ed intake has that kool vintage look and makes decent power
on modest FE's.
A cam with about 230* at .050 will really wake it up, but with the peanut size tank the gas gauge moves as fast as the tach.

If you use the F427 intake, make sure that you port match it to the heads.  As cast those intakes come with really narrow port openings, and I have data showing a 20 HP and 20 lb-ft gain from port matching, on a 410 HP 428CJ.

Even better would be a new Performer RPM intake.

Lastly, if your customer can spend a little more on cam and valvetrain stuff, get him a nice hydraulic roller cam.  You can pick up another big chunk of power going that route.

Jay--I was thinking the same on going with the Performer RPM, the cam will need to be a flat tappet hyd.  Budget doesn't allow for a roller, having to purchase a new steering box to install while the motor is removed.  The heads are c8oe with the n.  Haven't gotten the engine out quite yet(damned rusted header bolts!!! anything besides anti-seize to put on the new bolts during the install?) so don't know the cc's on the chambers.  Car is a c6 with a 3.91 gear.  The cj heads will have to be reused, just wanting cam/intake suggestions.  I know there has to be something better than the current Melling grind in the motor, it's probably 20+ year technology.

Next question.
What converter?
A good 10 inch will make more of a change than all the cam you can think of.
You want the converter in the 2500 to 3000 rpm plus stall range.

From the little I drove the car, literaly 150Ft, it doesn't seem like it has much of a stall if any, and the paperwork with the car doesn't show one.  Only that it's a built c-6 with a manual valve body.  Will check the convertor for brand and size once the engine is removed.
