:BangHead:Crap! I broke the housing. Well this retard will be down grading to a 273 cast steel pump. But I will not rest until I find out were this pump comes from. It could be for a marine application.
It's leaking from the (pee hole) on the underside. I need the shorter pump or the fan will hit the radiator, and driver side inlet. And I'm extremely curious what this old speed part is. I have never seen any other like it.
Hello everyone. I have a short pre 69 style 273 water pump in my street/racecar that start leaking. It's about 4.8" long and made of ALUMINIUM with 8 blade impeller. Need help to identify this pump. Is it an old 70s race piece?? Can't find any info.
well I have a manual trans and no linelock so the car will jump forward a little bit before I can hold it still, and it´s no water there(very small waterbox). I have to almost floor it to hold the rpm between 6000-6900. I can´t hold it perfekt still and car want´s to move forwards, this is in 2...
I have assemble all of my engines my self. The only ting I can´t do my self is honing and balance a rotating assembly. I now have an other shop that doing all of my honing and balancing.
And my tune was not off ( no pinging, 12.2-12.7 af. ,plugs ok, timing 35 deg)
I strongly think that all of...

The causes:

2. Gas washed the oil of the walls ( flooded last burnout )
3. Discolour on walls made by heat (no oil on walls ) and chemicals in octane boosters.
4. Dents with...
Hello Motorworks. Don't know if a torque plate was used but yes the bores is out of roundness big time. The idle af. has always been at 13-13.5 and the plugs looked good. af. at full throttle 12.2 -12.7 .
Yes the car did flooded the last time out and only fired on 5-6 cylinders after the burnout, but it cleared right up just before I staged. Mmmm sounds like the last burnout nailed the last nail in the coffin.
Never took the sparkplugs out on the track, I just loaded it up and went home, but...
Okey I finally took the thumb out of my a## and checked the engine block.
I took a Hammer and cracked the cylinder walls in big pieces.
The thinnest spot I could find was 0.110
I then took my new sonic tester and calibrated it with the cylinder wall pieces so it would be as accurate as...
