DriveTrain / Backfiring
« Last post by streetrodder1974 on December 13, 2017, 01:16:56 PM »
Picked up a 1978 Trans am with a 400 in it. For some reason the previous owner put an old  point type distributor in it, so I converted it back to the HEI.  Put a new distributor, cap,rotor, coil, plugs and wires, now it keeps backfiring  through the carburetor.  The plugs are set at the right gap .045. I did install a new intake and carburetor because he also had to big of a carburetor and it was dumping way to much gas in the motor. Did a compression check and 3 of the cylinders were showing 80psi, the rest were at 100-110 psi . I was told that to much fuel could be the cause of low compression. Any reasons why it could  be backfiring and is true about having to much gas in the cylinders

forgot a pic of the hood, paint cracked bad and came off and let it surface rust on the majority of the panel, I got it cheap so figure why not any hood is better then none and 400 for a new repop is out of the question right now. I plan to strip it down, sand it, use one of those rust removal discs on it and then treat it with rust reformer stuff, then self etch or epoxy the whole hood.

It's not just ebay, prices for these in good condition is a fair bit. You can now get them new and plated, nothing to repair and reweld and no missing springs, for not much more, still not cheap.

you wouldnt fit a 350 chev instead of the 403 if you already have the setup for it, torque rules on the street. I'd expect most chrome brake parts would be cheap n nasty generic items so do you homework as you won't expect them to operate as well or last long with the chrome plating.

Restoration Projects / my 79 trans am project in wv
« Last post by swims350 on December 12, 2017, 08:42:04 PM »
I just traded for this a couple weeks back, been wanting one for years. My dad had a 79-81 t-top he did in candy apple red back in the 90's was blue when he got it, don't know much more on it, then his friend had a 78 hardtop t/a it was black they did it in white, first car I ever drove.

Anyways pretty solid car, got an olds403 and th350 that were in it, and got a chevy 350 and chevy th350 not sure what I'll use. The 403 was pulled from a PO to get body work and paint done, got water in it, locked it up, I free'd it and tore it down to rebuild. I got almost every part to rebuild the chevy 350 but nothing for the 403.

Car has solid floors, they had replaced one portion before, trunk looks good, had some patches done on the 1/4's and fenders before paint is ok, was done 4-5 years ago, and never put back together. I got quite a bit of new parts with it, door panels, one white, one been dyed red, I don't like. The seats were dyed red too, wanting to do em in black, I guess re dye in black, i tried to remove what was on them but it wasn't working and I didn't want to risk ruining the vinyl itself.

Anyways the worst part is my roof, it had a sunroof, somebody removed and tried to patch it but they overlapped it and used a good thick coat of bondo which cracked and came off. I can't weld or I'd just weld it up right, and I can't afford to pay for someone to do it right either.

I know my garage sucks, but it's better then out in the open and aint the first one I've built in it before.

I have to upload the pics to host and post so hang in there

Aftermarket Questions / chrome booster, MC, and stainless brake lines

Anyone done them? I've got a 79 TA 403 auto, going to rebuild it with mild lopey cam, or maybe a 350 chevy same setup. The car came to me with no booster or MC and most of th elines junk.

So if you used it what size 7 or 8 sinlge or dual?

1 inch or 1-1/8 master? disc front drum rear

Tried the chrome brackets for f body? If so from who and how was the fit? Hood still close etc.

stainless lines, what brand? worth it? problems having to tighten, loosen and repeat to seal? not wanting to make my own lines, looking for some pre bent and flared, if not I'll get pre flares straights of reg. line at chain parts stores.

I assume with the master I need one with 9/16 and 1/2 fitting to use with said line kits?

Also considering a chrome prop. valve.

I'm not looking to do hydro boost, too much, and stock replacements are almost as much if not more then chrome.

Car is not and will not be original, I don't even have the trim tag so no clue on stock options etc.

Thanks for the info.  Where is the engine code located on the factory invoice?  I see the WS6 performance option but no engine code?
