Re: Lowering octane

You can get 85 octane in Denver/Colorado Springs area...I would assume it would be available at other high elevation city’s

70’s-80’s era low rise single plane intakes

I’ve been reading through some of my old early 70’s-early 80’s car and engine magazines lately, and now I’m curious. How good or bad was all the old small single plane intakes...weiand excelerator, street masters, street dominators, torquers, etc? There are a lot of fuel economy articles from back t...

Re: Ignition advance at cruise rpm?

Just thinking out loud here... How would you be changing the compression? Either with a head or piston change, wouldn’t you be completely changing the burn characteristics, requiring you to have to completely start over on your tuning? Or, different way of looking at it. It takes X amount of power t...

Re: Electrical system troubleshooting

I decided to try testing the battery again, as I couldn’t remember any exact numbers from testing it last time. Charged the battery for a while, got it up to 12.43V. Left it in the garage, unhooked from the charger...24 hours later it was at 12.00V. 48 hours later it was at 11.56V. Took it back to t...

Re: Budget 385sbc upgrades...too much compression?

I honestly liked the original combo better. It hit a lot harder right off the bottom, even if it didn’t rev out nearly as well.

But...not my car, not my money!

Re: Budget 385sbc upgrades...too much compression?

The owner made the decision to use what he had, so after a 14 hour thrash yesterday, then a couple more hours this morning to double check valve lash and give everything a once over, it is done. With 18* in the distributor, 12 initial and a conservative timing curve (full advance in at 3600), there ...

Re: Budget 385sbc upgrades...too much compression?

If you have tune up close and coolant temps under control i think you will be fine. I have run similar compression with aggressive comp oval track SFT cams with 1.6 rockers and tight LSA (106) in my streeter at 3650 pounds with over 70 passes per year and plenty of street driving. On engine disasse...

Re: Budget 385sbc upgrades...too much compression?

So here is the way I understand it... This guy had this 385 built a couple years ago. He thought it had the 67cc SR Torquer heads and 12cc dished pistons, plus this 278 Energizer cam. He loved the engine...loads of bottom end tire frying torque but it was done by 5200 rpms. His corvette buddies talk...

Budget 385sbc upgrades...too much compression?

4.040x3.75” sbc, hypereutectic 2vr flat tops w/5cc valve reliefs, .010” deck clearance, 4.166x.041” head gaskets. Old combo had 76cc SR Torquer heads for about 9.5 compression and a 222@.050 Crane single pattern HFT cam, performer 2101 intake and a 750 Edelbrock carb. Ran fine on 91 octane. New part...

Re: Electrical system troubleshooting

When disconnected, the battery voltage only drops a very tiny amount. I don’t remember the exact numbers but it was very small. Unfortunately the battery has ran down quite a number of times, as I don’t drive this thing hardly at all. I’m probably going to put it up for sale for this reason...sittin...

Electrical system troubleshooting

Apologies if this is the wrong place to put this... I’m having an issue with my 1999 C2500 suburban. With a fully charged battery, if it sits for 48 hours there isn’t enough juice left in the battery to start the truck. It will just turn over very slowly for a few revolutions and then just click. Wi...

Re: Testing for a worn timing chain

Travis, The big single roller chains in those engines seem to last forever without stretching. My 99 Tahoe has 280K miles on it with no issues at all. I have had some marine engines with over 1000 hours of run time and the chains still look about the same as new. Are you having an actual problem or...
