Best modifications/changes to full size classics??


Hey
I need your opinions, I like to get lists ready on what needs to be done or what should be done.
Besides an engine rebuild what are components that you think should be added/or changed to make these boats move even quicker/better and things to improve handling?

For example, are drum brakes okay, or should they be changed?
Is a sway bar worth it?
Any modifications to the transmission, etc..

Thanks, Mike

The easiest mods are polyurethane bushings for sway bars front and back. The next would be rear upper / lower control arms. The arms are c channel design , modifying the arms and boxing them in are a good idea. The bushings in those arms are rubber and replacing them with poly is also a good move. I would check and see if anyone makes a rear arm set for your application. As for performance the skys the limit. What do you want the car to do?.The car is a cruiser not a drag racer ,but power is good. The people at TA performance know there stuff i would call them to get a starting point on the motor mods.

Thanks for the points. I am starting to make a list.

What do you think about an aluminum drive shaft?


I want to get it powerful, and move good. But I don't want to modify the hood either when it comes to modifying the engine and worrying about clearance issues. TA has some good cylinder heads, but will the intake manifolds be a problem for clearance?

My own predeliction is to keep it looking stock (pretty much) but update the innards.

I would suggest:  An overdrive tranny (auto or standard)
                             Disc brake conversion
                             Internal conversion to breakerless distributor (pertronixs)
                             Rear sway bay with better bushings
                             Some nice rallys
                             Lower her down a bit
                             Good radials.
                             Rumpy Dual exhaust out of the factory manifolds
                             Hidden sound system
                             some cool working factory options.
               
                                           
Some of this I have done to mine but it's a long ways from being on the road again

I figure you'll make her young again and have a car you could drive across Canada if you wanted to with that stuff.

Good list Ken.
I was thinking of getting headers instead of keeping the manifolds.

So far
I have on my list. Would cost a lot, so have to start working on it little by little.

Radial T/As
Alum. Driveshaft
Coil Springs
Shocks
Rear sway bar
Disc brake conversion
Dual exhaust to 2.5 or 3 inch
TA shorty headers



Edelbrock Cylinder heads
Edelbrock intake manifold
Rough Idle/or Big Mutha thumpr cam
430 Rebuild kit

Will this give me what I am looking for?
I also forgot to ask.
I don't think my Riviera has posi, is this going to be a problem if I take it to a drag strip (if I ever decide too)? Is not having one going to add time?

The only reason I mention the stock manifolds is that in my experience the car tends to run a bit quieter on the highway, they seal better and they don't burn out over time.  My experience with headers is a long time ago so they they probably have improved a lot since then.

I'm over 50 so for me quiet is kind of my goal but if it isn't yours go for the headers!
