Every consider going with a roller cam and yep its possible?

If that interest you, crane, shneider and crower would be the first places I would contact.

I am guessing the camshaft would come in a plain white box.

 

yeah i did but i don't know if i can afford it. I woul dlove to get a roller cam/lifters/rockers combo..big fan of crower my self. a little expensive but the make great products. Never heard of shneider before...do they sponser any racers?

edit: It's funny the first thing you see on there website is "Who Runs a Schneider Cam?"

edit2: the only roller cams they offer are solid and HUGE. Don't wan tsolid because of the efi setup making it harder to get to valves and just for ease of use. Don;t think i need to go solid seeing that i will never eclipse ~6000 rpm limit of hydraulic lifters. Do however really like one of there hydraulic flat tappet cams there list price is 250 and there resale price is 162.50 which one would i pay? resale seems...well....used.

edit3: neither crower or crane have roller cams for the 300 according to their website.

 

Better make sure the cam you get will work with the POS computer Ford put in the trucks with 300's.

 

If you want to increase the lift on a cam with shorter duration it might be worth it to go with higher ratio rockers. If your engine is EFI you need the rocker for a Ford 3.8 V6. Harland Sharp makes adjustable ones in both 1.73 and 1.8 ratios.

 

hell if harland sharp makes a 1.8 I can leave the cam and get the lift with the roller rockers!! the 3.8's will fit the EFI ehh?? same pedestal mount? or are they adjustable stud mount.

 

They are pedestal mount. The rockers on my truck are stock 3.8 rockers with the pedestal cut down 0.030".

 

Another thing to consider is that clearance is pretty tight in the pushrod hole. There might not be enough room to run 1.8's without grinding out the pushrod holes in the head.

 

Rocker ratio = lift at the valve
1.7 = .423
1.75= .435
1.8 = .448

If your looking for "budget", look at the mellings 240/300 "high torque" cam (they only offer one) or the PAW performance (which I believe is the same and list for $59). Now the reason I listed the rocker ratio = lift at valve earlier, this cam will give you .451/.475 at the valve with a 1.6 rocker, an more duration with an exhaust bias. I conversed with a guy that ran this in his speed density truck, he commented it really woke it up and had no noticable negative effects, your results may vary, then again emissions testing was not required, so that aspect is an unknown. This will give you an excuse to install a steel timing set vs the stock phenolic. To give you an idea of this camshafts potential, look at col. flashmans build and dyno results, heck, a person could believe those results were inflated, and IMO they are still not that bad.

FWIW, I contacted mellings for the actual timing specifics, they don't seem to have them.

who's cam is that mellings or PAW?

 

mellings, I believe clevite has the same camshaft, as well.

 

I dont wanna highjack the thread, but I have a carb'd 300 w/offy dp and holley 390. Its a daily driver and has 3.70's in it. I love low end and mid too. I like to keep it between 1000-5000. I have seen that i think its crane made a truck cam for the 300 that had different lift and exhaust. Does anyone know where i can find what im looking for? I see that Isky has a "turbo" cam that has the exact range im looking for.

Should also point out...


The mellings is listed with 280/289 adv. duration, 204/214 @ .050, .451/.475 lift

The PAW cam is listed as 270/280 adv. duration, 204/214 @ .050. .451/.475 lift

 

if i were to use the rockers out of a 3.8 what is the lift on them
