wow 10503 is crazy 3k to 6k
here's the run with 10503


10503

 

Had to go back and find one of my old Hi-Per Parts books to find the actual specs for the CJ cam.
Looks like Lunati's cam has the same lift as a CJ cam( .481 I - .490 E) but has a good bit more duration (304 I - 324 E) verses ( 270 I - 280 E) this is also more duration than the factory C8AX cam (282 I - 296 E)
That would explain it's higher rpm potential.
C6OZ-6250-B is a CJ cam, specs are
Intake at 0 lift
O= 18btc
C= 72abc

Exhaust at 0 lift
O= 82bbc
C= 28atc

Overlap
46

Duration
270 I
280 E

Lift
.481 I
.490 E

The factory C8AX-6250-C specs are

Intake at 0 lift
O= 24
C= 78

Exhaust at 0 lift
O= 82
C= 34

Overlap
58

Duration
282 I
296 E

Lift
.500 to .515 depending on which chart I look at

With that info can you run the factory CJ cam or both

 

i'll run the CJ tonight

 

Sorry about the long time away. I had a BBQ Competition on Saturday and they are A LOT of work. I am really liking the look of the 62002 numbers. Right in the trucks wheelhouse. I am planning on going with a roller setup, Eddy heads and intake, and Sniper EFI. It looks like the Lunati 20330710 is the roller version of the 62002. Would you be able to run that cam on the dyno please? And possibly the 20330711?

 

Lunati doesn't list a cam card for the 20330710 or any Roller . I sent them an Email asking for Cam specs . I'll run when I get Info

 

guess Lunati doesn't want to give out valve timings , I'll run specs I have tonight .

 

here's the run with the C8ax-6250c


c8az cam

 

20330711 cam
the roller Lunati 20330711

 

Looks like the original C8AX-C is a better cam than Lunati's version.
I'm interested in seeing how mild the stock C6OZ-B CJ cam is
The 428 CJ I had in a 73 F-100 pulled hard off the line and seemed to make good power up to 4000+
Had a stock sounding idle so wouldn't be ones choice if them wanted a little thump and bump sound.

 

and finally the c60z-9250-b


c60z-6250-b

 

 

Yes you will need the Lunati retro roller rockers . ( 72336-16 ) or the cam kit 20330711lk comes with cam and rockers

 

Ya I planned on getting the kit with lifters but what about rockers. Would I have to run a roller rocker kit such as Harland Sharp or can I run stock rockers?

 

sorry mis-read that . I had a long rough week end .
to tell the truth i don't know for sure .
I am sure it would be best to go Roller rockers too .

 

For a cam with the amount of lift the 20330711 has you'll need a good rocker system with end stand supports to help prevent the rocker shafts from breaking on the ends.
