    Biggest cam with flat-tops-no reliefs

    in Nissan L6 Forum

    Posted

    Ok well,what if the bottom end is fully stock, 0 miles and the only mod to block was a set of flat top pistons sitting say .17 thou above deck.n47 shaved .10thou 480 lift cam,lots of over lap. Considering all of this, would the over lap be the determining factor as to P2V clearance?

    Hey guys,im building another l28 this summer.I have a fully ported mn47 head shaved .10 thousandths. The block is balanced,and fully refreshed with stock bore flat tops.(no valve reliefs)...the cam I am wanting to run is 295durr/495 lift...will I have any clearance issues with this cam? Id like to run it degreed at 4-8 degrees advanced. Thanks for the input.

    4 barrel set up higher than 390cfm

    Hey,

    I thought Id write this up due to the mis conception about the 4 barrel set up. I have ad ztheropy su carbs,tripple mikunies and the holley set up.all are great set ups,each having there benefits.

     

    The common issue I see is people saying that a 600+ cfm carb on,a 2.8l engine wont work well..WRONG.

    And size carb will work from 390-1000cfm! If you step away from the typical su carbs and tripples and actually take the time to learn how to properly tune a 4 barrel carburetor,you will see that a 650cfm dubble pumper can be ran effectively on our engines! Its all about booster signals,jets,air bleeds,power valves and patients. There are many guys out there who run the holly set up.the ones who dont like it,dont understand carburetor tuning.I honestly like the 4 barrel set up over the tripples.there cost vs performance is so close ya cant beat it.try to find a triple carb set up for less than $500 USD.so all you guys out there bashing the 4 barrel set up,give it a try and have someone who knows 4 barrels set it up.its a much cheaper option than tripples.As far as #1-#6 cylinders running lean,instal annular boosters to get better fuel atomization.I have yet to see proof that there is a lean condition. Btw,love this site! Donating next month!

    Cheers.

    To get 300hp n/a is going to take lots of time on the head work,correct camshaft choice,compression being between 10.5 to 12:1+...then its short gear transmissions,low gear differential,drag or street slicks,and then you get into suspension

    Hey,

    So I understand I can just go with SDS or megasquirt.I already have a ported AZC 4 barrel manifold.I have been lookibg at the Atomic EFI from MSD. Self tuning,flows 900cfm.which I like due to the fact it will let the engine pull in its max cfm with ease.has annular style fuel boosters for maximum throttle responce and is good for hookin up to msd 6al box to control ignition all hands free....has anyone done this? Its good from 200hp-650hp engines.
