Separate names with a comma.
Had a competitor sit out of competition for 14 years before returning this year. He had alky from back than. We checked the specific gravity and...
I should start by saying that motor has been running a consistent 1/2 burn on the plugs until thursday night when it leaned to about a full round,...
I wonder if we are talking apples and oranges:confused: aka Hemi vs conventional chevy Last friday I leaned out one motor, torched the head,...
Mike, to my eyes I would call it burned down 2 threads in cyl #8. What do you called burned threads? Maybe you could post a pic of one of your...
Our head guys tell us to be within about 50 thousands of the springs advertised "max lift" numbers to avoid spring surge. After some out of...
At the risk of talking about things people might not beleive, here I go. I'm confused about spring psi. I've experienced myself what great...
Going from 36 to 38's likely won't richen it enough, I would put the 42's in and try it. Figuring areas, adjust your main pill to compensate for...
By the joules, the only thing hotter than a 10+ is a 44 mag. So is it a good bang for the buck? I'd say it depends on what the rest of the motor...
The power makers are blowers and cylinder heads. Than you have to have good ignition to fire it and most of all, a properly tuned fuel system to...
If this is a conventional headed BBC I would probably not go over 13:1. The dome sticking in the chamber gets ugly, ignition timing wise. After...
They used to show up in a leakdown test, but now only if the valve is out and you spin it. Does titanium deal with the heat better?
Some of the import guys weld a "new/another deck" onto the top of there block to make it stronger.
You could also plug the blower rotor ends. When I ran LF HH 8-71 k8's, I plugged the rotor ends and picked up 8-9% in boost psi. Can...
The biggest bang for your buck (and quickest/easiest) is to simply increase the blower overdrive and give it some fuel.
It appears to me that too weak of valve springs limit RPM (valve float) and also heat warp valves. Since they are bouncing, they are not on the...
What's wrong with using an oil pan heater to do this? If you heat the oil to 160° before you make the run, wouldn't this "cook off" any alky...
I don't have experience with 14° heads with a blower above it, but if it were mine I would start with 25-26° ignition timing.
Any reason not to warm it to 180° right in the oil pan, while the motor is still together?
How do you determine when to change oil? Alcohol diluted oil certainly isn't good, but what indications tell you that it's time to get that oil...
When I see 14° heads, my first thought is timing in the mid to high 20's. The 14° NA stuff I help with doesn't run 32° advance and it doesn't...
