    Need a bit more oomph...

    First, determine what your gear ratio is. If it is overgeared, putting a more aggressive cam in it will only make it worse. What size tires and rims are you running? Larger diameter gives the effect of taller gearing. Lastly, how do you want it to perform? If you value off-the-line snap and...

    Factory smoke

    A quick way to see of the alternator is working is to see if the back of the rear bearing cover is magnetized when engine is running - strong magnet, it is good. Weak or not magnetic, bad alternator. J. B.

    Front bumper not mounted right

    This is a 73 - 80 frame. You could use the correct 73 - 80 bumper and brackets with no problem - it will look fine - or, if you want to use the 83 front bumper, you will need the correct brackets for that bumper. If you don't have another vehicle to use as a template, have a helper with you...

    Welcome to our community! Great looking Suburban! Remember, don't try to use one of those new style 0W motor oils! You might have dangerously low oil pressure! J. B.

    Rear disc conversion

    I would, instead, switch to a 14 bolt Full Floating rear end with 13 inch brakes. More bang for the buck. J. B.

    New or old

    Simple - drill mounting holes in the proper location through to top of your frame horns - first put the upper mounts in your bumper and have a helper hold the bumper in the proper location, then drill the mounting holes. For the lower mounts, use another set of upper mounts, you will have to do...

    I would be afraid of flammable refrigerants. What if it started leaking into the car, and you lit a match? KA BOOM! J. B.

    Gas cap

    All 1970 and newer have non-vented caps, or are supposed to. The tanks are supposed to be vented via the Evap system. J. B.

    Stumped on oil leak

    Good that you found the cause of the oil getting on the headers, but putting RTV on the timing gear cover will be a temporary fix at best, as oil in back of it will eventually push it off. If cap screws on the cover are all properly tightened, then you need to remove it and clean the mating...

    3 on the tree

    Powerglides are fine for small blocks and MILD big blocks that are not much more than 400 cubes, but I wouldn't put one in back of a souped big block. J. B.

    3 on the tree

    I think you need the Tremac. Yes, it is rare on a GM vehicle, but that's what my 73 C25 has, and is what was put in back of 454s that had a 3 speed. Rare, but they do exist. It is the torque, more than horsepower, that can break gears. Stay away from the little pencil sharpener size units...

    Regearing Advice... What do I need?

    4:10 or 3:73 is what you need if you have an automatic are towing. If you have a stick, 4:10 or maybe even 4:56 if you have the biggest tires. The LS is more of an RPM motor than the regular Small Block, so you need shorter gears. J. B.

    What yr grill is this ?

    This is about 75 - 77. Later ones didn't have the engine size, 73 - 74 was different - recessed in the grille frame, rather than flush with it. J. B.

    USA made sliding window assembly?

    I wish I could find new guides for mine, as I also don't like using foreign-made trash on my 73. J.B.

    What's the good AC compressor these days?

    Either the A6 or a Sanden. Stay away from the R4. J. B.

    (Advice) PCV Valve strange issue.

    Better replace those head gaskets right away. Coolant in the engine oil is bad, as when hot, it leaves a gritty residue in the oil and causes bad wear, as it is an abrasive. J. B.

    Making sure inverted flare cooler lines seal

    What's even worse is when they don't tighten one, skip one, but tighten them in a 1 2 3 order and warp your rims or brake drums. J. B.
