Idk its my trade so I have a feel for it. <br /> <br /> The adjusters are like 10lb then 24lb and the cam sprocket is like 40-45lb depending where you look. Valve cover is 7ish... Idk the mech fuel pump but w/e tight enough is how much lol</p></blockquote> Lol got u.

Lol it's like a shopping list but u forgot the about the MILK,eggs,bread?? Lol. THX man! Torx spec for all the parts I need to removed in order to install the cam?

What's the torx spec?

Ill wait till the cam comes in, I'll put it in then take measurements.

<blockquote class='ipsBlockquote'data-author="banzai510(hainz)" data-cid="815244" data-time="1355858866"><p> putting the cam in the towers is EZ if straight. its the sizeing of the lash pads and ther retainers.<br /> <br /> <br /> since you got the 440 you might be able to use the stock retainers and use about a 160 size lash pads. I would set the lash to like .006 and .008 to mak sure the lash pad dont flop out as alot of the pad will be taller than the retainer.<br /> <br /> If your lucky like me I bought a set of 150 up to 200 back in the day so I got all the sizes covered.</p></blockquote> So the dealer sure have these in stock? For such an old motor?

<blockquote class='ipsBlockquote'data-author="72240z" data-cid="815293" data-time="1355863644"><p> I'm down to help, just take hainz advice and order a range of lash pads. Try your best have everything prior so you dont get stuck.</p></blockquote> Kool THX. I will I'll head to the dealer 2mrow. I should have everything by the new year.

hey do you want to hook up and help me install the cam? i can meet you or you can come to me what ever makes it easy?

DAM why can't you guys be here in the EAST COAST!!!!!! :blush: :blush: :blush:

<blockquote class='ipsBlockquote'data-author="banzai510(hainz)" data-cid="815154" data-time="1355843597"><p> to me a 450 isnt worth even buying. compared to the cam you intially wanted is a huge difference in size<br /> But sounds like your rich. and in a rush.<br /> <br /> <br /> <br /> I have a 460/270 in my 521 L16 w 32/36 and I think they sould have made that cam stock in all the L motors.</p></blockquote> I'm not rich I'm my own boss. I have a wife with a great job too:-) she wants me to stop riding bikes so I pick up this hobby:-) ill try this cam if I don't like it ill be shopping for a bigger one..

<blockquote class='ipsBlockquote'data-author="banzai510(hainz)" data-cid="815145" data-time="1355842134"><p> webcams has a 488 252 dur cam I would pick that one<br /> the 450 one you posted remeber you got to subtract the valve lash as that will be your real lift.<br /> L motors like lift.<br /> Remember they might have to grind the cam as the waiting period can take a month at least.<br /> The webcams are new cores if you want a outright one.<br /> <br /> There have been a few people said they got Isky cams before but never mentioned that they needed cores before.<br /> Nissanmotorsports might have new cams laying around.<br /> <br /> Schneider doesnt have new ones either but will do a core. if a regrind youll end up using close to 190 200 lash pads<br /> <br /> lash cap size depends on if head, valve seats and valves are machined as it all affects the wipe pattern.also it if the valve stems are event across the top. as soem people trim the tops also to make them even so one size pad is needed.<br /> I seen heads were every rocker needed a different size(bad news as you want close to 1 size. You can be off a little and not worry about it.<br /> Ill let Sealick take over as he knows the tricks to get by now on this</p></blockquote> I know it takes a month that's y I got the 450, they had one left new.. I wanted the 488 but had to wait. The 450 ill get it by Friday got the tracking#.

<blockquote class='ipsBlockquote'data-author="datzenmike" data-cid="814819" data-time="1355795137"><p> Because of the measuring at 0.050" lift this is comparing apples to oranges except the valve lift and duration. I don't know what the stock valve opening and closings would be at 0.050".<br /> <br /> It does have a respectable lift and is under the need for replacement springs due to coil binding. 12 degrees of added duration will move the power band upwards by just over 500 RPMs... say about 6K-ish.<br /> <br /> <br /> <br /> Just for fun I messed with a cam calculator and with the 108/110 lobe center and keeping the following...<br /> <br /> <em class='bbc'>Your cam has an Overlap of 41.00 degrees<br /> Intake Duration of 260.00 degrees.<br /> The Exhaust Duration is 260.00 degrees.<br /> The Inlet Cam has an Installed Centerline of 108.00 degrees ATDC.<br /> The exhaust cam has an Installed Centerline of 111.00 degrees BTDC.</em><br /> <br /> I have<br /> Intake Opens 22°BTDC<br /> <br /> Intake Closes 58°ABDC<br /> <br /> Exhaust Opens 61°BBDC<br /> <br /> Exhaust Closes 19°ATDC<br /> <br /> I basically added 6 degrees on either side of the cam lobe. I'll bet there are different way to get the same specs.</p></blockquote> Hey mike what size lash cap I need?

Ok so I called ISKY CAM to see what's up with my order? And they charged me but never called me to tell me that they don't have any CORDS!!! So I cancel,-((((( but I found this WEB CAMS in CALI. They had this cam left: Intake Exhaust Valve Lash (Inch): .007" .011" Valve Lift (Inch): 0.450 0.450 Valve Lift (mm): 11.43 11.43 Advertised Duration: 260° 260° Duration @ 0.050": 238° 238° Lobe Center: 108° 111° = 109.5° Overall Intake Opens 11° Before TDC Exhaust Opens 50° Before BDC Intake Closes 47° After BDC Exhaust Closes 8° After TDC Valve Timing Is Checked With Zero Valve Lash @ 0.050 Inches Of Valve Lift. So I think this would be a better cam? Not to crazy?? But my question is the lash cap? What size?? .160? .170? .180? Don't know? I'm heading to Nissan 2mrow. Any body?

bump.bump,,,come on guys could used some cash for XMASSSSS

Ok now I love you guys cause you know stuff, and get me out of a lot of JAMS!!! But this MSD IS INSANE:-))) car is running sooooo much better good starts and great runs so far. I'm waiting for the ISKY CAM then I'm heading for a dyno. THX:-))

That's how I hook it up. Car starts up right alway and runs good. Going to take it out to see how it drivers.

Sorry I just saw ur answer at the bottom. Yea I need to read it again I'm sure MSD booklet said resistor

Ok put I want to installed a MSD box and MSD coil?

My car came with a pertronix ignition, and the resistor was being used? Some people tell I don't need it? The MSD book tells me I don't need it it I'm using ignition? What to do?
