Hey scrap
I just have to ask you this them If i didn't deside to Make up grades to my 250 That I raced For 17yrs (about two years of that 17 as a daily driver) with NO tear downs And the bearings, rings
Cam still In A one shape. As a daily driver this
motor was Pushing between 13-15-1 compression
When I desided to use it more as a racer I dropped
the compression To keep from replaceing the head gasket after 3-4 runs Because I didn't have studs in the block.Because Most events I went to were at least 2-3 day events.
The Motor was broke in with 10w30 first fire up
no stat temp around 190-200 TOPs 20-30 min run
time Shut down Stone cold Install stat changed oil & filter. Refired Back to 190 run another 20-30 again 10w30 and Cooled.Refired and 50 miles at varying mph 30,40 50,60 Repet ,bring home change the oil and filter 10w40 for then Next 100 miles
changed everything again.Ran it again varying mph.
Then at about 200 miles or so There after It seen
nothing but 20w50.That motor was built with a
583/607 mech cam and ran like i said between 13/15-1 compression, Yes it was my Daily driver
it had a 4speed and 3:08 gears and I got about 16
mpgs city. as long as I didn't have my foot stuck in the carb.LOL And it also seen weekend track time.But come monday I was putting in a new head gasket.But as long as I didn't rpm it Like i did
at the track I had no gasket issues on the street.
And I broke in My v8 things in the same manner.
The only time I have ever seen someone have a
issue getting rings to seal right Is when Chrome
moly rings were used With Out the right final
hone(cross hatch) in the bores. Personaly I don't
like chrome moly rings.
But i do understand what your saying, but my
personal oppion is I don't like to see any temp
much over 200 in my Motor.
Another thing I like to add Is I DON"T Used anti
freeze In any of my Fresh Motor Builds Till i am 100% sure there are no leaks Meaning No Oil to water or visversa.Because anti freeze can wipe out
the bearings on a fresh motor.
again just my2cents
God doesn't like ugly.
