Matthew takes you through the first start on the freshly redone 5.0 in the 1990 Convertible. Engine upgrades include AFR 165 heads, a Trick Flow Stage 2 cam, Edelbrock Performer RPM II intake, long tubes, Flowmaster FlowFX exhaust, and a Western Motorsports big tube intake. Stay tuned for a followup video profiling the finished version of this car.
First Start videos on this channel show bone fide first ever startups and are not staged to appear easier or smoother than they really are. The idea is to give you some insight into the things that you should expect and be watching for when starting your own project for the first time.

Well done Mathew - very satisfying to see/hear all that hard work pay off during the first fire 👏

@tecmotiondyno 2 года назад

Yeah, after a few little adjustments it settled down and ran great right away. And that is basically an EVERYTHING changed project!

@markweber7275 Год назад

Slow & methodical with great explanations. Matthew enjoy your videos. Really helps us weekend mechanics👌👌👌

Really appreciate you sharing this experience. I'm getting very close to this point with my Fox Body project after it having been apart for quite some time. Great to see the challenges after the parts are all back together and prior to startup. Much success to you!

Static timing set at 13-14 degrees…that cam needs more advance on the crank than OEM.

@tecmotiondyno 3 месяца назад

All the timing is added in the software, which is the superior way to do it.

@poisnd1 3 месяца назад

I hear ya, A Static baseline and then adjust via software for that finite tune…that’s all I was saying.

Love the convertibles. Good job

@tecmotiondyno Год назад

I had another 90 convertible on the Dyno just the other day - same color but the top was replaced with a black one. In a world where people are crazy for the coupes, it’s interesting to remember that the GT Convertible was the king of the Mustang world when the Foxbodies were contemporary!

@krisf5247 2 года назад

Sounds great Mathew!👍🏻

@tecmotiondyno 2 года назад

Yeah, I really liked the FlowFX choice, especially for a ragtop. It is a classic sound but not as loud or insistent as the American Thunder system, and with the top down it will be a way better choice I think. Stay tuned for a coming video with a good walk-around look at the sound and some wide open on the Dyno!

I need to play with the timing of my car, she sounds great Sir

@tecmotiondyno 2 года назад

I have done these starts and been very close on the timing but for whatever reason I was way out on this one. Once I got decent base timing and got the throttle stop opened a little more, it ran pretty clean. I have footage with an owner interview, a good look at the finished car, Dyno, and Dyno comparison for the project that I will edit into a profile video that will be coming soon, so stay tuned for that.

@johnsampson7791 11 месяцев назад

How do you know your at top dead center on #1?

@tecmotiondyno 11 месяцев назад

Rotate the engine until the timing pointer on the balancer is at the TDC or “0” mark. If you assembled it right, you can pull the distributor cap and check the rotor position. When the crankshaft is at TDC and the rotor is roughly pointed at the #1 terminal you are on the compression stroke.

Very Informative channel,I just recently rebuilt my 302 in a 93 coupe with a hci combo upon intial start up,it idled fine after idling awhile it died and now won't stay on unless I feather the gas,any ideas as to what the problem could be?

@tecmotiondyno Год назад

There are so many possibilities that it is hard to give you an honest answer. This particular car had the throttle stop set to low so turning the screw in (to hold the throttle open slightly wider when closed) sorted that problem out. If it has a non stock MAF and injectors, it probably needs programming adjustments too, as this car did. I’m going to suggest this video on some other common things that are wrong with these cars too: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--W5QwwIAhv4.html

Great video! I’m in the process of starting my new build soon and you have highlighted some good things to check before start up, thanks! When you ran the fuel pump did you jump the fuel pump relay? Or did you jump it at the diagnostic port?

@tecmotiondyno Год назад

I have aftermarket wiring and a big pump in this car so I jumped it at the aftermarket relay to do a fuel system pressure check/leak check before final assembly.

Was there any PTV clearance issues running AFR heads with the TF stage 2 cam? Is it still a stock bottom end? Did the pistons need to be fly cut? Good content keep up the good work!

@tecmotiondyno 2 года назад

I tried several colors and they were all worse without laying a solid background down, so I compromised with yellow. A voiceover interfered with the video too. Hopefully the yellow titles can be read if you pause it.

@patrickrice6752 Год назад

For some strange reason I been having a issue starting the car back up after it reaches operations temperature...... Tried everything under the sun..... Found out fuel pressure was up to high and made that adjustment..... Any ideas

@tecmotiondyno Год назад

It's hard to make a diagnosis based on these vague symptoms and no information about the modifications. If you have an aftermarket fuel rail setup and you dead-ended the fuel rails, you can boil the fuel in the rails after it sits for a brief period of time when hot and that can lead to hard starts. You could have a bad regulator. There could be a tuning problem. Or it could be something else.

Ever figure out why the factory gauge wasn’t working?

@tecmotiondyno 2 года назад

Apparently it was bad before and I didn’t realize it. This car got new Autometer oil pressure and water temp gauges with Tecmotion vent pods so I didn’t spend time diagnosing the oil pressure gauge problem. The main thing is that the motor makes good oil pressure, but you sure shouldn’t start it without confirming that!

@AwakeDude911 11 месяцев назад

im assuming the idle is about 1500 as the 700 wants to die right out?

@tecmotiondyno 11 месяцев назад

This is a genuine first start which includes the timing a little off, the throttle stop set a little low, and a need for some initial tuning adjustments. Once these settings were all sorted out the car settled down and idled cleanly around 800. This cam setup generally needs between 750 and 850 for a clean idle.

@AwakeDude911 11 месяцев назад

@@tecmotiondyno cant get the timing right on my TF stage 2 cam either dies out or wont start after it gets warm ...been playing with the timing but seems fine 1 min the next it dies out . gets hot wont start to a running point till it cools down . will any sensors effect this ? my brand new oil sender went out after 3 months and was reading zero but i could tell it wasnt zero as it wasnt clanging inside the motor . new Chinese sensors i dont trust but thats all they make these days ..

@tecmotiondyno 11 месяцев назад

@AwakeDude911 Step one is to time it with a timing light. Once it is timed correctly you can start worrying about other things. In the example of this first start, I timed it, then made a few small programming changes to the mixture, and then when it still wouldn’t stay running I realized that the throttle stop needed to be adjusted to open it up a bit more. If you have bad sensors of course they can cause problems. You might find some help in one of these videos too: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--W5QwwIAhv4.html and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-U8uBEaA07GY.html

@newheart1109 Год назад

Good job Matthew. I have a question.I have a cam with 224/230 duration at 50 and 512/512 lift with 110 lsa. Do you think it will be ok to run this cam with the stock heads on my 87 5.0 roller motor? I will be changing the springs for extra lift. Just wondering about the clearance. It had a e303 cam but I have pulled it out to go a little bigger.Thanks.

@newheart1109 Год назад

forgot to say it is switched to carb.5 speed ,355 gears.

@tecmotiondyno Год назад

The stock heads have little valves and usually don’t have clearance issues. Their big problem is the crappy spring package and the stamped steel rocker arms. I usually figure that it isn’t worth money retrofitting E7’s when cheap Chinese aluminum heads are better, but if you are prepared to get a decent spring, rocker arm, and pushrod package on them I would expect a cam like that to clear the pistons fine. I would do a P/V check just to be sure if it is practical.

wms intake? are you in Canada?

@tecmotiondyno Год назад

Yes, the shop is in Calgary, Alberta. Actually, the prototype fitting for that big tube WMS cold air intake was done in my shop on a 393 Foxbody project we had in, and it got the first one. The WMS cold air is about the only truly big tube commercial cold air intake out there for the Foxbody these days ...
