Yeah, it was a numbering update. One of life's mini-mysteries solved...9,999,999,999 to go...

 

That is fine for a carbed 300-6 but Crane doesnt recommend the 503901 or the 503905 for a fuel injected 300-6. They tell me I need the 500511 is the one for efi engines. It specs at .429I .458x lift and 192* and 204* at .050" 112*LC ground 4*adv and about $200 from summit. Any ideas?

 

machman, the powermax cam and the ones u listed are the same and i have it in my EFI 300...dont lissen to em...

 

thanks aot crane it is!!!

 

Hey Optikal, Are you saying you have the 503901/503905? Is that the powermax cam? Has your mileage suffered or stayed the same? What year is your truck? I am playing with a stock 95 m5od short bed. Will this cam fit the bill for a mild stock upgrade? When I do the cam, I am also doing the single cat/new muffler thing. That is about it. What do you think?

 

i have the powermax cam, both of those are the same for the most part. i have a 1993 f-150 with an E4OD. the cam does good for what i want. not sure about the milage as im pullin around 33s with 3:55s so its all down hill. i also suggest steel cam gears from advanced, they sell for like $40. also, a high flow cat with a good exhaust to follow will do ya fine. dont forget new lifters!

 

So far my list consists of : cam,lifters,steel timing set,possibly pushrods and rockers,oil pump,all gaskets and a high flow single cat with an aftermarket muffler. I think this should do it. How many teeth are on the Advance gear setup? I have seen both the coarse tooth and the fine tooth versions. I know Sealed Power(Federal Mogul) offers a 92 tooth (fine) steel cam gear setup.

 

oh wow im not sure...sorry.

 

Just out of curiosity, is there any advantages to either one?

 

either cam? or cam gears? my guess for the cam gears is noise...

 

The gears. From what I have read on the cams,they are the same 503901 and 503905. Seems like the usual corporate numbering shuffle. I think I am going to try and go with the fine tooth set if I can find them.

sounds like a plan man, good luck.

FYI, cloytes makes some adjustable cam gears where u can advanced or retard the overall cam timing +/- 3 degrees.

 

I will let you know how it turns out. Thanks

 

What is the advantage of advancing the cam?
