Build Thread My Never Ending 89 Notch Thread

Some aftermarket harmonic balancers and flywheels come as a universal part. You bolt on the weight for either 28 Oz. or 50 Oz. The stock late model cranks were all 50 Oz.

On any balance or vibration problem, I would look closely at the stock harmonic balancer first. They are known for slipping the outer ring and causing an imbalance.

thanks joe , the balancer that was on the motor was a 1 piece unit from dayco(power bond ) SFI unit and double key wayed by the machine shop . I swapped it with a. new frpp I already had to try to narrow the issue down and that wasn't the cause .

Put stock TRANS mount In re assembled everything and changed the oil . Much nicer to drive again we are back in business for now I am just gonna keep running it . oil looked good not metallic or copper like . I took a sample to have tested I need to cut the filter as well

Street cars go to work in the rain ? DD needs an alt

 

[hoopty5.0]

I too drove mine to work in the rain today. Although instead of an alt, I need a P/S rack. Mine locks up like its catching on something and I almost put it into a curb yesterday leaving work.

Picked up 31 spline axles for 50 bucks . I have been driving the car non stop since Monday night and despite the damn vibration the car has been flawless . cleaned it today and put it away , I got the DD up and running last night but didn't want to put the car away esp dirty

 

[stangboy]

You putting it away already?!?! Is the winter weather rolling in this early? It's not even officially Fall yet.

 

[TOOLOW91]

no I meant back in the garage lol

 

[TOOLOW91]

I use it year as long as there is snow or salt

 

[hoopty5.0]

That's a good deal on the axles!

 

[FoxMustangLvr]

Are the axles 4 lug? Going to keep your gearing the same ratio when you get new ones to install the axles?

yeah they are . I plan on going 5 lug just not anytime soon and going up to 373 id like it to be a little more violent .

You have 3.55's right? I've never experienced those but I love my 3.73's a lot! My car is probably a fancy glove slap to the face while your's is more like a punch.

I'm thinking the weights are bunching up on the pressure plate . well see . I have been using the car though

 

[TOOLOW91]

Made a shake down pass it went 13.55 at 110 with a 60 . didn't do a burn out didn't let air out of tires . just slipped the clutch real hard and eased into it .

Next pass I aired it down - 17lbs Left at like 28-3k spun a little but not too much 2.2 60 13.22 at 109 and change . 12s are there just need seat time I am happy for 2 passes
