Well before LS engines existed we could still get performance engines to run cool in traffic. Does it still have a suitable shroud?

I've emailed you a diagram for 1980 and 1981, one is a fairly large file but the second is similar in layout.

DriveTrain / 461 Pontiac Mill - Runs Cool - Heats Up In Slow Traffic
« Last post by Texiam on May 05, 2019, 02:06:54 PM »
Pretty common problem I guess for those of us that did Not go with LS Engines like we should have. I'm looking to see if others have had and solved the issue.

I'm a little premature asking because I will be having a pro tune soon whereas it will be properly timed ect. which very well could have been my problem for some time. As indicated, 461, Comp XE268 cam. I "had" a FlowKooler older design water pump and as indicated, it ran fine but in traffic, it didn't always do the job. I now have the latest version but haven't run it in the summer yet. I "had" a stock engine fan with a severe duty fan clutch. It did okay, it cycled, it let the temp run up a bit and then kick on and roar. It too though had terrible moments of high temp. I am installing as we speak a Flex-A-Lite duel electric set up with a total of 3000cfm.

I've described all of this just to see who else out there has experienced it but my simple question in closing, will 3000cfm cool this thing, AC going, in traffic? I feel as though it 3000cfm minimum but anyone else needed to go more?

Thanks, Tex

Electrical / electric choke help
« Last post by Newfiedan on May 05, 2019, 10:08:51 AM »
I am working on my best friends 1980 trans am turbo and we have been going through the car and doing the basic maintenance items, I just recently did the plugs, wires and cap/rotor and new hei coil. When we were done it was idling high (1000 rpm) I checked the timing and it is bang on so I went looking for a vac leak (it needs new vac lines but none found) and I did find that the electric choke wire was broken off (not sure where it goes to) and the screws for the adjustment were loose. Does anyone have a pdf manual I can download or at least a schematic for me to work off of so I can get that wire connected properly and then work on adjusting the electric choke? When I hooked up power to it the idle went down to 650rpm but it caused stalling when in gear.

I'm from Hartsville Tn. I've been reading this forum for years and I'm pretty sure I've seen the whole restoration forum. I've got a 2001 WS6 6 speed but I'm really looking for a 77 or 78 y82. I've been looking for about 15-20 years for the right car though.

Hi all... This forum is great. New kid on the block here and I know just enough to be dangerous, so this site will help immensely.
I just picked up my first Trans Am over the weekend and after driving all day to check it out, I wasn't in the right frame of mind when it came to the sell. The body, interior, undercarriage and engine all looked great but when I asked to start it I knew I just got craiglisted. I was told the starter was bad and that was it, so I took their word for it,  trailered it home at the full asking price (8K), and replaced the starter with a Summitt Mini the next day. It started up and engine was rough and missing somewhere and after running compression test, I found #5 cylinder had about half the compression as the others in this supposedly pumped up 400.
I thought about replacing the engine and tranny to an LS, or a pumped up 5.3 or 6.0/6.2, but after reading a lot of the info here, a lot of the guys here keep the 400 and maybe go with fuel injection. I'm looking for some reliability, maybe 17-20 mpg, and a smooth somewhat quiet driver with some horsepower. The guy that had this car before looks like he had it designed for 1/4 mile and with just the flowmasters on it, it sounds like an earthquake is happening when I start it up in the neighborhood.
If the engine is fixable at a cheap price maybe a fuel injection system is the way to go, but if it's costs a couple grand to repair I might as well spend another 3-5k on a complete swap.

Please chime in... Any info is appreciated... And it's ok to call me a dumb-a** for not driving or starting it before I handed them the cash. My wife has been doing that for a week now  ;D....LOL

General Discussion / Help needed. New to the US, want my car with me.

Hey guys,

I recently immigrated to the US (from a small country called Denmark) and would like for my 79 Trans Am to follow me. The problem is that at some point a gen4 454 BigBlockChevy was fitted. I dont understand legal English but I am pretty sure that it doesn't qualify as "OEM original from the factory" as I have been tolled by EPA import lines, that it needs to be. I need help to figure out my options. I dont want to do something illegal, since I would like to stay in the country with my wife (who is American). The car was bought by me dad and it was the last project we had before he died of Parkinson's a few years ago, so the car means a lot to me.
Hope someone can give me some advice

Thanks in advance
