Re: Idea for pre lubing oil galleries

Why not just terminate the ignition and crank it for 10 seconds or 15 seconds or until when the gauge twitches a couple pounds?

Re: Opinions of guides in import heads

From what I've seen over the years, the issue is the QC and not so much the materials. They are either too tight, too loose or atypical size that can be hard to find. Makes sense in the regard that the minimizing the price point means bargain bucket shopping for anything that will work. If they are ...

Re: Timing Curve

4V vacuum secondary carbs don't have four corner idle so the valves should be shut. All idle A/F must go through the primaries. Ideally. Opening the secondary on these carbs is like adding a controlled air leak. A tiny bit prolly won't hurt but thats air not be accounted for and too much of it means...

Re: When are you switching to synthetic?

My engine guys say “we filled the pan already with synthetic, if it ain’t broke in by turn one, bring it back”. They have done around 1 per week for the last 30 years so I’d guess if it mattered, they would see em but they never come back till the snow flies. To save me the headache, I do what the b...

Re: Did Penn Grade 1 change their formula?

I’d think it would be dumb to assume it wouldn’t change to keep up with vendor changes, supply changes and general technology and industry standards. Everyone hopes the changes are for the better but I guess we don’t really know until the consumers try it and report back. I’m going to keep using it ...

Re: SBC water pump questions

Buy a Stewart pump and you'll have it the rest of your life probably.

You cannot move too much water. Not possible. Physics don't work that way.
Your thermostat will control the warm up period.

Re: Tight lash camshaft questions

I was under the impression the lash ramp can be ground into the cam pretty much where ever you want it.
"Tight Lash" does sound like a good marketing term and inflates the numbers a bit.

Re: Decking a 350 OEM block - How Much?

How far out are we talking? And yes, I was going to attack with a nice sharp burr.... Repeating with different words. Machine decks to suit. Machine China rail to match Machine intake side of heads or intake manifold to fit. Then see if you have to do any slotting and/or port matching. So one ends ...

Re: Distributor Gear Wear

High pump loads and thick oils are hard on dizzy gears.
What oil?
What pump?
What gear?

I don't trust anything. I'd take it apart and wash it with hot soapy water and bottle brushes in the galleys and reassemble.

Re: Need input on this cam breakage

Wow. Broke in the middle of a lobe. Someone working in the shipping department has been eating his Wheaties. When we ship a cam, it's bagged, then tightly wrapped in corrugated paper, then tightly put into a heavy walled box, and both ends are stuffed with paper, to keep the cam from moving around....

I got one too. I started with junk though.
Still got junk but in smaller pieces. Somehow the crank is the only part that survived.

Re: Need input on this cam breakage

I shipped a Subaru WRX engine to be rebuilt to the Upper Northwest from Mo and when it came back it was on the pallet, upside down, with a box covering two halves. Somehow they managed to break the damn thing in half. I spend some time with UPS and FedEx for work and I've witnessed just how much the...
