914World.com _ 914World Garage _ First freeway drive on new build
Posted by: barefoot Dec 21 2019, 10:25 AM
2056 with Dell 40's, WEB 494 cam flat top pistons with calculated 8.8 CR (case decked .010 & no head or base gaskets). Small OD tires on 15" rims, so way too many RPM's for highway travel. I fitted type J thermocouple with digital readout on #3 cylinder spark plug.
I'd bench calibrated this to 210 degrees with water I'd boiled in a cup, so am pretty sure it reads correctly, but was very surprised with how low head temp maintained. This meter shows about 65 deg before starting motor, so it's cold junction compensated OK.
Cars & coffee this morning with outside temp at 50 deg. Oil temp gage stayed below half scale & Freeway RPM's at about 3300. Exhaust tips an electrodes are dull black but not sooty. Timing was set by my tuner & my timing lite is shot, so can't confirm timing, but engine pulls strong.
anyone have similar experiences ??
