HELP!!!
The clutch and slave cylinder have been replaced. After bleeding the clutch several times and several ways the pedal will only hold firm for a few minutes. Then, it is back to a very soft pedal and resistance going into gear. Any ideas??

So to begin I have worked with engine diagnosis and repair in a general sense but never with performance tweaking an engine, just stock engines. I'd like some advisement on what to look for in a used performance engine. I have the opportunity to buy a 400. 30,000 miles. Has a decent but not pouring amount of oil around the breathers. Owner seemed to have had fun with it so probably hard driving. I've forgotten what it came out of, something mid to late 70s. At any rate I'm not entirely sure what 'built' really means. And how to interpret the condition. He said it's got a steel crank and a hot cam. He told me the lift but I've forgotten that as well. Professional built by someone else. Had 10.5:1 compression and was bored .40 over I believe. Not sure exactly what had been done to the heads or what they came off. They were Chevrolet heads from something else... Stock manifold and 650 carter 4bbl with vacuum secondaries. He had some interesting stories of being crazy with it. Going sideways, burnouts, 4 wheel drive burnouts, hijinks of all kinds... but for what it's worth 30 thousand miles... It's old and the paint is rusting off a decent amount and it's been sitting 6 months to a year. Poured a bit of gas down the carb and it fired right up, then died of course. Some smoke, not a ton. Sounded good... angry, like from being woken from it's half dead sleep. I can get it in trade and am wondering how you guys think it will perform and how much life's left in it. Kinda a crapshoot without hearing it really run. It didn't knock or anything when fired and the oil looks ok; not clean, not super dirty, no coolant. I have a compression tester and need to go out and check it... Opinions? What kinda horsepower can I assume here? What should I ask him about the motor? Any input is appreciated.

Hello everyone, new member here. I just picked up my dream car. An 86 Olds 442, with a nicely built sbc in it. I can't tell what is done internally with the engine, but it sure does run nicely. What I can tell you about the car/engine is, it has hump back heads, aluminum radiator, dual electric fans, Speed Demon 650 carb on a dual plane intake, th400 tranny, ceramic coated headers, duals with H pipe, and dressed nicely too. Like I said it runs and sounds great. I just wish I knew what was going on internally with this thing! :confused:

I was putting the water pump pulley on the engine yesterday and ran into a little problem. This is my first attempt at a restoration and am still learning so be gentle. Here it is...the engine is a rebuilt 73 chevy BB installed in a 67 corvette. The water pump pulley hits the balancer by about 1/8th of an inch. I did notice the balancer is wider than the original that was on the original engine in the car The water pump albeit new is that same as the original. My question is what do I do? can the water pump pulley be shimmed? I would hate to replace the balancer with a different one too much work and $$ but if that is what I need to do I will. Any help would be greatly appreciated...Thanks..Jim http://i42.tinypic.com/ay9a9x.jpg

To start with hello to all from NC. I'm a new member with a big question. I have a 1996 2dr 4wd Tahoe that i am wanting to build a little than some may think. I want to build the ultiment traving SUV. I want to build a blower motor that will get me still good gas milage ( by the way i'm getting 22mpg highway )more power and torque. Don't really want a turbo motor, and the only reason for the blower is for quick power when i need it. Can anyone help me spec this out, as far as some general stuff, i will be running stock size tires or maybe one size larger stock is 265/70/16. Stock gearing i'm not sure the exact ratio but i think it is 3.08, Full power, A/C. It's fuel injected now but a change could be talked about. Will have headers. The motor is the original one with 213--- miles on it so if it needs boring, would be bored min of what i could get away with. Basicly i'm looking for the best of both worlds, good emmissions, mpg, torque, and power. If anyone would like to try and give me some advise i would be greatful. Who knows, this could turn out to be something good. Be blessed Phil

Has anyone put a Vortec I-6 in a '69 Camaro? I own a '69 convertible (electric top, still works). I want to restore it. It needs a new engine. Now, I love my '05 I-6 Trailblazer engine - 123K and it's still same as when I bought it new. I have not changed the spark plugs yet, let alone the fan belt or anything really. I only change oil every 10K and it burns NO oil (not a drop between changes). I originally wanted a V-8 for the Camaro, but now after owning this I-6, it's been the best engine I've owned in my life, easily - hands down. Is this possible or will the motor mounts be a big problem? I guess they'll be a "problem" but how much (?) is what I'd like to know, and if it's feasible. Thanks.

dadshogshop, your tall block is .400" taller than a reg block (10.2" vs. 9.8") and going with a longer than stock (6.135")is a step in the right direction. Manley has a 6.535" H beam 4340 moly rod that will work for your combo. The original truck pistons are very heavy and have 4 rings.,. the longer rod makes up the difference and a light piston can/should be used. Open ring end gap to .005" or .006" per inch of bore, or the rings will wrinkle, butt ends and collapse. I would not go with a 6-71 and run it straight up.,. or overdrive it for street apps. The reason being heat which will expand the air and result in a power loss. I would opt for an 8-71 and underdrive it 6 or 7 percent, for more air and less heat. Boost engines are not overly sensitive to valve or runner size.,. since the engine is pressure fed. Cam manufacturers are the people to contact for grinds that best suit your app.,. give them as much info as possible and also your expected red line. I would run 8 to 1 or a little less static compression,,,, but keep dynamic comp in mind.,. this is where intake closing comes into play. Again, the cam grinder would know best. Boost engines are usually run with race gas or a blend of pump and race.,. this depends on boost and combustion pressures generated. Roller lifters need to be meticulously set up for alignment and true tracking on the cam lobe, since the lifter bores are staggered on a BB.,. any caster wipes lobes real quick. Hope this helped. :)

MSD ignition is definitly worth the money...if you need it. If your running a stock or mildly modified motor gm hei is plenty of power for you. MSD ignition is made to fire when other wont like high compression situations or high rpm. While an MSD coil or box will give you a hotter spark you wont notice much difference in a stock motor. There caps will are better manufactured then oem parts and are more reliable but like i said if you dont have much done to your car you really dont need to spend the money!

:D Hi there,{BOB} I bought a heap of 307 parts and the Mains caps were all over the place.. Patience and a lot of it gave good results by trial and error by fitting the lubed.. crank and single caps turn it by hand freely until you have torqued the cap down to 70lbs. By the last cap you will probably need a 15" bar and socket but should turn O.K. Keep the crank well greased at all times..No big deal. Just eggsperiance.. :cool:
