Why rockers with stock cam?

Cheap way to get more lift

not really. cam and lifters run $208 and performance wise you gain a HELL of alot more.
comp stamped steel 1.7 roller rockers are $169 so savings aint worth it

 

[Mathius]

whatcha lookin to do with it? you want low end grunt and a lopey idle or ya lookin to run races? lol

the 351's are flat tappet cam engines and the roller cams require a retrofit kit to work and a complete roller cam will run about $500

flat tappet will do just fine (i'll be running one in my chevy... sbc cost about $700 to convert to roller)

You know Warriorgirl is right on a couple of points there...
I looked it up, and the windsors are a flat tappet cam.. (I thought they would be a roller to. But I'm not a ford fan)
Out of the 2 she posted, I like the numbers on the 270 better. Pretty good for being able to use a stock converter.

 

[warriorgirl09]

i like a rough idle and those are the 2 lowest rpm cams with a decent lopey idle with the best numbers. i love the magnum line of cams (the 270h) i like the 280h in a chevy! they have a wicked idle

 

['00 WO-YA!]

For every tenth you jump in the rocker ratio you'll gain about .030 on the lift and 3° of duration. Your late model Windsor may be roller cam ready you may just need to tap the bosses in the block for the spider and get a retainer kit. All the 5.0 **** will work to convert it. Also be careful in cam choice if you are still speed density. Longer duration cams will piss it off. Maybe a Motorsports"E" cam.

That's what a lot of people think, but you are better off with the cam. More duration and lift. I agree with you WG.

Comp cams. Definitely good choice

i am also a huge fan of bilstein shocks, i did rough country shocks when i did my 2 in lift...what a joke of a shock that was... had to shoot it in epoxy black cause they where white... no big deal but the gas charge in them sounds like a blown shock every time you hit a bump! drove me nuts!!! i swapped to bilstein shocks and the ride is night and day different, almost completely eliminated body roll as well. another good trick for more power out of truck and fast is intake and ported and polished TB... i ported and polished mine when we welded up the intake for it... the better flow gave me much better throttle response! i could not be happier! when i made my intake i did not make it drop low into the lower part of the engine bay as sometimes i get into some pretty deep snow and mud... i did not want to have to worry about getting the filter all wet and/or swamping it, it still stays pretty nice and cool where it sits now thanks to the circulation from the fan right there, i also gutted the splash guards from under the filter location to allow fresh cool air to come up alot easier. here are some pics (also the spectro filter is now gone and a K&N is in its place

after porting and polishing of the TB i also powder coated it

intake

That looks real nice man. I have a Spectre on my '03 Trailblazer. I noticed a difference.

Better cam is the way to go over lifters any day. You don't gain enough in lift or duration to make it worth while. Example, say your lift is .480 take that and divide it by your stock rocker ratio then multiply by the new ratio: .480/1.6= 0.3x1.7= 0.510. While that is decent for lift numbers, better performance can be had with more duration and different lobe seperation.

Anyone got any idea what i could do to my dakota r/t ?? Its 98 5.9 auto, so far I got lonestar trottle body, k&n cold air, edelbrock shorty's with flowmasters.. Im running 20's with the stock trans and rear

 

[Gen1Pat]

They have a super small cam. If you want to get into the engine, ugrade the valve train to accomodate more lift, clean up the ports, bowl blend them, then throw in a cam. Bout all there is left to do.

nope mine is the roller block not flat tappet its the 5.8l or 351H vin the little brother of the 351w mines efi, im just looking for more power all around but up top hp im only running 325ft lbs of torque with 214 hp about with my k&N filter

 

[buzzy613]

oh also i can run the mustag cobra roller cam or any 5.0 roller cam

 

[liftedhigh]

Wow this thread hurt my head. Has anyone in here ever actually built a performance engine?

351ci engine is to much displacement for the stock E7 heads and intake. No matter how big of a cam you put in there your intake and heads are a huge restriction. Swap out the heads and intake and open up the exhaust with longtubes and aftermarket exhaust and you will get a much larger hp gain then a cam swap. After the heads and intake swap then cam change and bore it out.

 

[liftedhigh]

No you cant you can only run 5.0HO cams in a 351.

If you have a 351H in your truck how did it get there seeing how they stopped producing it in 1974.

 

['00 WO-YA!]

Yeah, I said that on the last page but everyone is too busy arguing to actually pay attention.

Yup, several, and have done much studying and owned 2 5.0 Mustangs.

Yup, flow in E7 Heads peaks at right around .450 lift, guess what the lift of a 5.0 Mustang cam is.... .444. The E7 will do decent with some port work and a simple Motorsports E cam but again it needs to be mass air. Not much out there for 5.8 trucks as far as intake goes,.Edelbrock used to make a setup for them.

The Cobra cam was the same, Ford used a 1.7 rocker arm on it for the Cobra. It also used a cast version of the GT 40 intake. Engine mapping was also changed for the Cobra as was the mass air meter and injector size I believe. Upped to 24# instead of the typical 19#.

 

[Mathius]

All this ford talk is give'n me a headache to.. Just toss a SBC in there, and make some real power.. lmao
Just kidd'n, run what you brung.
But with all this talk on here, it would probably be better to just have someone build that SBF motor for ya. (Someone who has built one before, and will build what you want)
