It runs way better with premium.Drive my truck and you will want to buy it.

Way better how? I have full control of spark curve and I say it would be a lot of power gain to want to pay for premium on a 8.2:1 compression engine. Actually I'm running closer to 9:1 and have had no detonation issues on 87 octane.  Maybe I'll try a tank , but I doubt I'll be impressed.

I am looking at my 85 Nissan service manual ,but your's is a 80 model.So you have a Z20.The Z20 listed here is P185/80/14.You will need new rims also.Do you have 6 lug nuts.For mine it says P215/75R15 or P225/75R15*3

 

The '80 720 was the last year the L20B engine was used. 

 

'83 and up were Z20 and Z24. The Z20 was the mileage option engine.

I have the advantage of full timing control which keeps me from having to buy premium . It also allows for better performance overall. I really don’t even know what full timing is stock. It is a poor combustion design which makes things tougher to tune . I might try premium to see how far I can push timing . I’m about 37 degrees now at 100kpa . Run more like 45 below 70 kpa . These motors load really fast without much of a load which probably causes much of pinging

In another post you said if you have a working L20B engine you should sell it and I asked why and never got a answer 

[datzenmike]

Can you find it? I don't remember why I would say that.

 

This one?...

 

Your '79 with a blown HG and talk of a KA swap. Well for $30 if just a HG, fix it and have a running engine. Drive the truck and sort it out before the swap. (there's a chance you might even change your mind on the swap) Swapping a KA in is a lot of work to find that it needs major suspension, electrical  steering or brakes and who knows what else. Once swapped you have a running L20B rather than 280 pounds of scrap... it's worth more.

These motors load really fast without much of a load which probably causes much of pinging .I've had my 85 720 2.4 since 94 and never had a issue with timing.It has never been adjusted,I had a Jasper engine installer put a re manufactured engine in back in 2009,and now I have 80,000 miles on it.The reason I started using Premium cause long ago I was going up a hill and it started pinging.So I decided to try Premium gas and it never has pinged again.When I got my new heating and air installed not long ago,I had him check the compression and timing and he said it was good.The same guy that installed the Jasper.He is a expert on the 720's.He has one.My piston rings went bad in my engine back then so I had him put a Jasper engine in.The engine was 1900 bucks plus labor.It is a sweet engine.It's a 4x4,Total cost was about 3200.00.Since he had it out,he noticed the clutch needed replaced,no charge for labor,just cost for the clutch.

Really I get about 80-100 for the half tank and I never let it drop below half tank. I just always fill up for some reason at half. Takes 15 bucks to bring it back to full even at 3.51 a gallon

That makes four of us, but you have an 80KC. I looked, over a year for an 80, finally gave in and bought an 84. In Idaho no less--damn

Thomas, those BFGoodrich All Terains are 235/75/15s? Crazy, they actually look like 30's to me. I was contemplating getting 30's but these actually look beefier than I expected. Are those wheels 15X7s, do you happen to know what offset they are, and do they rub? If so where on the truck do the tires rub? I have the stocky wheels on my truck currently but the front wheels sit considerably further in the wheel well than my rear wheels. Not sure if this is normal. I really like the way the stock wheels look but I'm guessing I would need to add a spacer to the fronts to get them to sit closer to how the rears sit. I wouldn't think twice about running the stock wheels if they weren't so skinny, so I'm still on the fence on that one.

They are 15x7.They don't rub.Ive been running this size forever.31 rims will fit on 235 tires.I switched them over.Now,I have American Racing rims cause the center hubs fit.

It doesn't change the gas mileage or power either.For it been a 4x4,it will go.
