    Default E 30 cam? E88 head? anybody have any info on these?

    just curious about what im working with. the engine work was pre-me, wondering if its necessary for premium fuel, the previous owners mechanic said it was a big cam, and while it sounds mean with the header and big exhaust but i dont feel it. also, ive noticed a bunch of you using 20w50 oil, is there a reason why so heavy a weight? im in hawaii so i dont have to worry about starting under 60 degress but i dont want to ruin my engine with overly thick oil.

    E-30 is about right for an early e-88. As far as being a BIG cam-only some mics could show that. That cam could have been reground into a performer. As far feeling power, the butt dyno is decieving and if it's not dialed in right, it's might be worse.
    Oil, you don't need to run 20/50w. Will it hurt anything-probably not. 10/40 is plenty good, and synthetic is a plus.

    i assumed it was stock, it doesnt look clean enough to be a regrind or very new but i did sit for some time. i cant seem to get her to run good for more than a few days at a time. i set the points, clean the plugs, adjust the carbs, several times now and it slowlly goes back to running poorly by the end of a week. plugs are not fouling but they still look a bit rich. i do spend half the day at sea level and half at 3000 feet. im tuned at 3000 ft cause thats my house. assuming im running rich while on the coast.

    You need to define ' not running good'. Any other history on the motor will help

    Hi, regarding the oil. You might want to read the article on the site http://datsunzgarage.com/rebuild/ about 3/4 down the page under title Lubrication.
