I bought 5 or 6 NOS GM rear gear sets at an auction a few years ago. Most of them are still in the GM boxes. If I post the numbers I can find on them can any of you guys tell me what they are for? The ratios I can figure just by counting teeth but the applications I don't know. Once I get some info I can dec...

So, I'm thinking with the 327 I'm buying off Carl, when I rebuild it I'd use some Vortec heads and intake. This would give me the hardened valve seats for running no lead gas..plus they flow well so I should pick up some nice HP... So my question is this..is this a doable, inexpensive build....I'm no...

I need an engineer! I am looking for a crank pulley for a big block. I was sitting here looking at pulley pictures and remembered I have the identical pulley except it's for a small block and the pilot hole is wrong to centre it on the balancer.

Generally, on GM Radiators circa 67, what size are the line fittings? Are they 1/2-20 Inverted flare? Cheers, Mark

Guys, Can anyone tell me the diameter of a 69 SB fan? My plan is to install a new aluminum rad with a 69' shroud and a new 5 blade fan in my 67'. Make a custom spacer to allow for it. I have shrouds but no fan... I scrapped them, doh! And although I could measure the shroud, I realize you need a minimum clearan...

Frame off done the resto job but never decoded my engine because the engine looks rebuilded in the engines and is basically very nice and clena inside, so i only added the Edelbrock Tri Power system, an melling HP HV oil pump and an bigger oil pan for better cooling, Edelbrock water pump and and the rest...

Hi all, I recently acquired a '67 Parisienne and it has a Chev 307 in it, replacing the siezed 327 that came in it originally. I'm wondering what, if anything I can do performance wise with this engine. I've heard this can be a bit of a dog, but can be maximized out at 235 hp. If anyone has any ideas on ho...

(And don't say "55 horsepower") I see they use the exact same cylinder head, and same compression ratio. The 390hp gets dual exhaust. Is it just camshaft and exhaust? Any other differences that make up for the power difference? Thanks! Dave
