My Inheritance

Ok so I must be full of sh*t?? I will take a look at the tach soon. Maybe it is set wrong? For a four cylinder or something? When going down the highway it is definitely reviving too high and not right regardless. I have had several pickups with 4:10 gears and revved 3000 rpm going down the highway. It is definitely higher than that. I would love if one of you more noligable people came over and took a look at it and could tell me what I have, but that is not going to happen. This car will never be a good cruiser. I understand that. I am trying to make it more drivable, that is it. I don't have the time, money, or want to go drag racing all the time. I am trying to tame it down a little and be able to drive it 30 miles down the highway 60 mph. Judging by the tach in the car. It will not idle under 1000 rpm and it lopes up to around 3000 rpm. If you goose it in gear or not it will jump right to 10000rpm. I put 3:70 gears in it, thinking I can keep the rpms around 3000 going 60mph down the highway. Hoping it doesn't load up too bad. Right now it sure seems like it has a 5000 stall converter. Because it slips until the tach hits 5000 and then it hits and pulls hard. The engine doesn't not have off the shelf heads exactly. They are some old steel Merlin race heads that had a lot of work done to them. Dad started with the block and then found the heads. Then the engine was built around those parts. I know there is stud girders under the cheep valve covers and aftermarket main caps. Either way if it is 300 hrp or 1000 hrp it is a high strung raspy b*tch. Either way I have a cruising car, the Monte. This car is just a toy. I hope that you guys can help me make it do what I want with it. I also know that our Vega has a 396 10:1 engine, supposed to be 500 hrp does not rev like this one or have the same amount of power. I appreciate the recommendations and advice even if I don't want to hear it. Thanks guys.
 
Do you have a stand alone (diagnostic) tach you could hook up under the hood? I have an old 70's era diagnostic kit that includes a hand held tach/dwell meter with aligator clips. Dad has it right now but I also have an old autometer tach that used to be on the column in the Galaxie (replaced by a period correct Sun) that I could mail you. One wire on the hot side of the battery, the other on the negative side of the coil. I think verifying the tach is a good place to start so you know for sure how the converter is acting and then you can adjust from there.

10,000 RPM from a BBC is difficult to believe. 7500, sure. 6000 going down the highway doesn't sound right to me. I'd think it would be unbearable with loud exhaust. What is your rear tire height or tire size? It will wind on the highway with 3.70 gears and a three speed transmission but should be manageable.

I'm really glad to see the car is running and you got to take it to a show. That's awesome. The work in your update looks good. The car looks great.

3000 rpm with a 26-27” tall tire with 3.70 gears is about right. If it’s 6000 I would be checking the tach.
So this is the walk of shame! You guys were right. Tach was off. I borrowed a photo tach from a friend. Then I did a little research. I guess I never set up the tach when I first got it running. My dad installed the tach, but only started the car the one time. It was easy to do, but didn't know enough to do it. I took the car for a quick spin this afternoon. At 60 mph it is running 3000-3100 rpm. The torque converter does not feel like it is slipping at that rpm. 2000-2500 rpm it feels like it could be shipping a little? 3000 rpm seems to be a little under the power band of the engine, but drives ok. If you down shift at that rpm and hammer it, it revs up and goes. I think it will be ok? I did not drive it long because I have a fuel issue I need to fix. Need to add a fuel return system to it. Also it is running too hot. It got up to 210 in the short time I drove it. I am not sure if I need a better fan, or if it should have holes cut in the shroud? The radiator is pretty much blocked off except for the two fan holes. What do you guys think? 6500 rpm is about where it seems to run out of steam. Sound about right? I guess I bought into and believed the bullshit my dad sold me? Sorry for being an *ss. Thanks for the reality check.

You’re welcome. Feel free to message me for any other big block related questions.

At what temp do the fans come on? 210 is warmer than I want but isn't really hot.

No shame. Working behind someone (even your father)) can be difficult to figure out at times.

I'd say 'well done' as to removing one more issue that was on the list.

IIRC this car is loud, correct? If yes, then gauging rpm from sound is difficult for me.

Thank you and yes. This car is very load and raspy. 6000 rpm sounds way higher. I plan to change the mufflers for quieter ones this winter. They are Flowmasters.

It's a hydraulic coupler, it has a specific efficiency range - it is either in or out of it. Close still generates lots of heat. The diff ratio (and final drive ratio) need to match the converter... and nature/powerband of the engine.

It may be easier on everything to put the higher ratio back in. Even if it "feels" wrong.
