Re: Jeg's Hydraulic Lifters USA Made

Take a minute to read recent legislation on what can legally be called made in America, the amount of material, and various parts of it's manufacture that must be done in the USA And the percentage tables they used. They can import the bodies with wheel assembly installed, od ground to size. And ins...

Re: New spark plug design

A wise man once told me pay attention to what oems are doing when it comes to ignition system. They spend more than the GDP of many third world countries annually looking for even the faintest increases in combustion efficiency. And if there is merit to a particular design spark plug you will see it...

Re: New spark plug design

For even a guaranteed 1% increase in economy, performance or efficiency as long as it was a measurable consistent gain, the oems would have them as original equipment on everything they sell. The amount of time and money spent chasing better cafe average is staggering. But somehow they always manage...

Re: Custom one off serpentine pulley needed

custom pulleys for a reasonable price? I understand your meaning but it is a bit of a contradiction is it not? its a slight modification of an existing design. they normally charge 75-100 for. I am not opposed to paying 150-175 each for them, just hoping to not pay an insanely bloated price for wha...

Re: GM 383 oil pump screen installation

Aren't most of the small block stuff being done in mexico now? Wouldn't surprise me if they are assembling their crate engines there now too, at least the gen1 sbc stuff.

Re: Blaster Cabinet Help

While I have no specific blast cabinet to recommend, I have learned a few things regarding blasting over the last 50 years. Blast cabinets must not leak blasting media dust; a functioning vacuum media recovery system is critical. Blast cabinets must have adequate interior lighting. This becomes imp...

Custom one off serpentine pulley needed

Contacted March performance and they said no dice. I realize a local machine shop could make it, but I'm trying to not pay 300 or more for a very basic pulley. Any North American firms still doing semi custom pulleys for a reasonable price? All I need is 84-91 Corvette water pump pulley, exact size ...

Re: Oil and detonation, old but interesting.

Thanks. I really appreciate you taking the time to explain it to me.

Makes me wonder why the recent push for direct injection/higher compression from OEM/EPA. If they can do it with 50 year old mpfi technology? Do the di engines burn that much cleaner? Or are they just that much more fuel efficient?

Re: Oil and detonation, old but interesting.

Low rpm high load na compression engine on pump gas mpfi is what I was thinking when I posted this. See similar thing in these types of engines? Like a typical 10.5-11 street engine, heavy car/ truck low stall etc. Torque builds with almost too much static compression pushing the boundaries of pump ...

Oil and detonation, old but interesting.

Curious if any of you guys have seen a higher knock threshold with different oils in higher compression street/strip cars. This world probably be more applicable to a mpfi setup than it would be to a carb/tbi setup. Hoping this will stir some interesting conversation, trying to learn. Thanks guys! h...

Re: Dynamic comp 9.5

So basically you don't know where the cam is. Nobody is going to be able to give you any concrete advice, nor will you be able to determine dcr until you have degreed the cam in, and know exactly where it's at. Not trying to pick at you, but saying "it's ground like this, and I installed it dot to d...

Re: Replacement for Proffesional Products 80003

Hard to go wrong with pioneer replacement parts. Order one for a 400 if you want to stay with the 8" damper. Kmj and others sell a 6.75" that's quite a bit lighter if you're wanting to take a pound or so off the nose of the crank. Either is 100 or less. Pretty sure the same Chinese firm is making th...

Re: Seeking advice on a 383 SBC build

Speedpro h859cp30 has a 12 cc dish with valve reliefs. Zero decked with a 5.7 rod and 64cc head and felpro 1003 (.041) comes out just shy of 10.5:1. 5/64 rings but pretty cheap. For a low rpm engine like you are describing they would work. Less than $200 a set with rings and pins. Blueprint uses the...

Re: Piston guided rods

While we're on this subject, how do you "guide" your rods? 1. One builder whom I respect spends many hours making individual aluminum spacers to insure each rod journal has three equal spaces. 2. One builder who claims no comebacks just stretches spirolocs and puts one on each side between the rod ...

Re: Realistic Octane Requirements

I am starting a new SBC 400 build and have some logistics questions. The goal is to have a reliable and fun street motor that also teaches me a lot about building an engine. Its semi budget but more about learning how to build an engine, something I've never done before. I just had the donor 400 CI...
