Re: Nylon fuel lines

The best Copper line ( easier to work with ) might be an option to consider where you mentioned running the steel line ?? Mark H. You ever see Copper fuel plumbing on a car built in the US? Far as I know, copper fuel plumbing is actually illegal in the USA. I have heard of English cars using copper...

Re: 350 oldsmobile

head gaskets all the same?,waterpumps too? Far as I know, there's no differences in Olds BB / SB water passages in the head gaskets There's three or four different "lengths" of water pump, but the impeller should be the same size. The cast impeller seems to be preferred over the stamped-sheetmetal ...

Closer to the rocker cup is better, IF (big IF) the gudeplate fits properly otherwise.

Re: open deck cylinder towers

The way my machinist talks, new Subaru four-poppers should come with extra head gaskets in the trunk. They're practically a maintenance item.

Re: open deck cylinder towers

with the headbolts well out of the way of the bores, what difference does it make? No disrespect intended. The "Pontiac" engine has the headbolts anchored to the water jacket, not the cylinders. Those blocks move around like crazy when you torque the head bolts. There's no knowing how the block wil...

How much piston slap are you prepared to put up with?

What is the intended use of the vehicle?

Re: SBC 383. Blow by

Removed the carb today, looked down the intake runners. I can see where the bottom edge of the fel-pro 1205 gasket has raised up to where the printo-seal is visable. I had a 1205 issue that was similar. My fault, not the gasket maker's--I just used a gasket set that had too-large port openings. Ove...

Re: SBC 383. Blow by

Update. Flipped the breather and PCV around; pcv on driver side. Replaced the hose to catch can w/ clear reinforced hose. I can see an oil trail flowing up the hose to the catch can. Excessive blow-by, or insufficient baffling. Maybe both. layed painters paper (thin)over valve cover (pcv) hole. Whe...

Re: Electrical system troubleshooting

I have a Trailblazer that would go about a month before failing to crank the engine--and that was with driving nearly every day. Charge the battery overnight, it'd go about another month. New Optima battery. I tested parasitic draw, alternator output volts/amps, starter draw volts/amps, cleaned the ...

I've got a near-stock 5.7L TBI small-block in a K1500 that looks a lot like your photo. Torched the head, too.

When the head gasket fails, that damage is just a matter of running-time.

Re: Ignition timing questions

The strange thing (to me) is that the optimal timing curve seems fairly advanced compared to almost all the recommendations I see for timing... ...All the recommendations I see out there for an engine like mine are in the range of 14-18 initial, 34-38 all in. If I use those settings the engine feel...

The Olds forums I'm on would DEARLY love to see photos of a solid-main-web 403.

They've been looking for one for decades and never seen one.

I've got a riding lawn-mower that has a tiny (3" or so) brake rotor built into the transaxle. It's an oil-bath brake; the rotor and the "pads" are steel.

So, sure, there are some goofy applications for brake-in-oil.

Re: 427 tall deck help

The OEM pistons are tall, heavy, and have four rings instead of the more usual three. They're a waste of effort. Don't even consider using them. You can use all sorts of different combinations of piston, rod length, and stroke to make normal 3-ring pistons work. When it was GM doing the mods to the ...
