526-531 lift cam with a 290 duration... all roller, all forged internals... 373 gears steeda underdrive pullies, mac full length comp headers ram air intake 70mm throttle body 77mm maf all ported and polished intake manifold and heads it runs
What's that?

maverick351ci

that would be specs to a motor let me brake it down for you

526-531 lift cam with a 290 duration... all roller (CAM SHAFT SPECS)

all forged internals (RODS CRANK)

373 gears steeda underdrive pullies (FRONT ASSESORY PULLYS)

mac full length comp headers (HEADERS / EXHAUST)

ram air intake 70mm throttle body 77mm maf (INTAKE)

all ported and polished intake manifold and heads (HEADS HAVE BEEN PORTED (OPENED UP) POLISHED (SMOTHED OUT))

dont know if this is what your asking kinda veg in your post

I've never seen a part roller cam myself

wonder if its solid or hydraulic. Lots of duration for a hydrualic (not normally a problem, but if the components are out of whack (springs not matched to cam, high ratio rocker arms, ect.) the engine will lose steam in the upper rev range (usually hyd roller motors seem to start to go south sometime after 5500 rpm)

Explain what you Just said

Nathan_H

Any of you guys notice a big difference between the DOHC and SOHC Ford motors?????? Personally, i notice a difference, but also, they are different size engines, meh...

Nathan_H

for instance, between a DOHC focus, and a SOHC 5.0

Nathan_H

oh sorry, DOHC-dual over head cams
SOHC-single over head cam

whats he is saying about the part not being matched to the cam is....

the cam has alot of duration and since it has alot of duration it almost has to have a perty decant lift.... if it has the wrong springs you will get lifter jump as in the lifter will try to ramp off the cam lobe and being its a roller it will dammage the cam and lifter

you can get valve float witch it the same thing as i just said above but more harsh all valves do it and you lose power becuse all valves are open

solid vs hydraulic roller

main advantage of hydralic its quiet and takes no mantnence after setting the valve lash

solid you have to adjust the valve lash just about every oil change

beings its a roller cam the duration isnt as harsh as a normal flat tappet cam is with the same specs roller cams will allwas have more duration becuse the lifter has to ramp up and down the lobe

Duration explaned
duration is simply how long the valves will be held open as the cam turns 360 degrees

Lift explaned
lift is how high or how far it will open the valve
lift is the max the valve will open as the cam turns 360 degrees
lift is multiplyed by the rocker arms so if you want more lift you go from 1.5 ratio to 1.6 and vise versa for less lift

most hyd roller motors are set up wrong i personlly run a hyd rollor set up on my car and it still runs strong from idle to 8500 rpm its all in the compenits you chose they need to be matching in your valve train like he said or else there will be problems in the future


hope this ramble helps

I suspect full roller meant roller tappets and roller rockers, you can have one without the other.

Solid roller=the way to go for high RPM engines.

Bo408

Both
