tune up

i recently tuned up the motor, changed all vacum lines, adjusted the valves, just basic maintence, and thursday i
towed my bass boat 76 miles to the pecos river, now normally
my highway speed fully loaded with bass boat in tow was around 45 mph, after said maintence, im able to cruise
the highway at 70 mph, but hills still pull me down, will a after market cam help me maintain speed?

Re: tune up

UHHHH the pecos river has enough water in it to flote a boat WOW!!! I live in ohio but drive a truck for a living and go from El Paso to Lake Orin Mi. each week I spend one of my nights onthe road at the Flying J in Pecos each week. (Tuesday Night) I guess it actualy has been kind of wet around there this year! I see your from New Mexico must be more water up there [img]images/icons/smile.gif[/img] As to a cam I've heard they help some but not as muchas you would think.

Re: tune up

Wouldn't need the long block I would think, just the Sumo II head should do him just fine. That's the reason we have 80 mph zuks out here in AZ. :-)

Re: tune up

You have a 2" exhaust, is that with or without a header? Also have you tuned the card since the exhaust? you might be a tad lean. The O2 sensor and the ECU are suposed to correct for that, but its generally set uo to correct to a lean condition, not to richen it.

Tack a digital VOM on to the O2 sensor wire, and set it for the 2 V setting if it has one. (it should) You should be from 500-800 mA (.5-.8V) at say 2500 rpm. If your lower, your a bit lean. You could also try a reading under load. I have a phone wire strand run into my cab so I can take a reading at will, and plan on a permanant readout to add to my gauges.
