(Recently sold to client) Was pinging real bad at 3000 rpm's coming out of the hole,
(90 model 5.7L, Thunderbird IV, fresh rebuild everything)
Had timing at spec, 8 degree idle, verified advance curve, by the book.
Had to retard the timming to 0 degrees at idle to make pinging all but gone. Slight random ping at 4k.
However, temp still climbing to 200 at that high of RPM. (NEW half closed cooling system SeaKamp with 160 degree stat)
Seems to have good flow but (NEW Aluminum) risers and mans are getting hot. Verified with IR temp gun.
I haven't gotten around to do the clear hose test, although I have the hose!
Some restriction somewhere.
Scheduled to replace impeller (again) this week. I'm off to Vegas for a trade show this week (Real day job)
So I am going to let my shop buddies replace the impeller while I'm gone.
More to come......
