Re: SBC 383. Blow by

After the oil from the leaky gaskets gets mixed into the charge and causes detonation and breaks stuff, yes it will.

Re: Ignition Education needed

Erm... "between the pickup and coil" - maybe for clarity I should say between pickup coil and module. The wiring between module and ignition coil should stay the same, if you're keeping it that is, if your EFI doesn't have it's own coil driver(s). When you add something like a MSD box, that splices ...

Re: Ignition Education needed

"HEI" is just a conventional electronic ignition system that happens to have all the usually-separate components located inside the distributor. Re-wire it however you like. Yes, you can absolutely splice in another device to control timing between the pickup and coil. Lock out all the mechanical/va...

Re: Upper control arm bushing materials

Not exactly relevant but I gotta say, man do I love Delrin. I've used it for feedscrew nuts and handwheel bushings in machinery rebuilds/upgrades. It can be set up with negative clearance on moving/rotating parts and still runs smooth as butter and lasts nearly forever.

If you keep getting unsatisfactory answers, maybe you need to ask better questions.

Re: Too late for a half fill?

That distortion is an advantage, it makes things stronger. I thought the reason for using filler was to make things stronger, apparently the goal is to make your wallet lighter in exchange for nothing but peace of mind.

Re: Quiet external EFI fuel pump experience

I managed to build one that worked great, carbureted, using Arduino, Aeromotive A1000 pump, and a homemade 3-mosfets-in-parallel driver board. Pump speed was default at 30%, variable up to 100% between 30 and 60% throttle, and/or 100% at anything over 100KPA MAP. Also used an oil pressure switch as ...

Re: Comp LSR lobes

As if choosing a cam isn't creating enough angst (I have had a few dreams involving valve springs), reality has presented another option: do nothing. (for now) DOD is disabled in the tune as a preventative measure so it's not gonna fail if it never gets used. Engine runs nice. Even with stock everyt...

Re: Too late for a half fill?

Is a filler that doesn't expand when cured really going to be effective? It might make you feel better knowing it's in there, but is it really doing anything? There needs to be preload or else once loads are applied, things will still move until they meet some resistance. Preload is good. Preload is...

Re: Electrical system troubleshooting

It doesn't matter if there is a light staying on if it's drawing only 20mA. 20mA will not kill a good battery in 48 hours. It is one of 3 things. One, the draw is actually higher than what was measured. Two, some module is waking up after more than 20 minutes and drawing far more than 20mA. Three, t...

Re: Electrical system troubleshooting

An internal self-discharge (wow, that sounds dirty) is tricky to spot with a tester. When fully/freshly charged the battery will have good capacity. But, the way to pin that down is to check if it still goes flat over X amount of time with the cables disconnected. I had an Optima that decided one da...

Re: Comp LSR lobes

Do I need to keep open pressure under 400 with stock rockers, or is that internet myth? The recommended Comp 26926 (505lb-in) are 146 seat/449 open. PAC 1904 (370lb-in) are 150 seat/372 open. 6000 RPM max. Stock rockers w/ CHE bushings. 106g intake/97g exhaust valves. edit: PAC-1905: 392lb-in 160 se...

Can we please use LSA and ICL? 'LCA' is not an actual thing.
