How much faster?
Looking for predictions. Here's what I'm doing:
- Replacing the stock drum brakes with a Wilwood lightweight disk setup.
- Replacing the stock cast-iron master cylinder with a lightweight alumunum Mopar unit.
- Replacing the stock Mopar distributor with an MSD Billet unit.
- Replacing the .048 thick head gaskets with .039 thick gaskets.
- Getting rid of the coolant leaking into the oil.
- Replacing the stock 19" 2 row radiator with a 26" alumunim radiator.
- Replacing the 60A alternator with an 80A 1-wire unit, upgrading the wire to 4ga.
I know that none of these are real performance enhancements, aside from the distributor & maybe head gaskets. But it all should lighten the car up some. How much faster do you think it'll go?

These heads were already ported, polished & milled, I really wasn't planning on doing anything else to them.

the rear suspension.
By the way I'm haveing the same Size and stall speed put in mine as we type
And if you hook I would now say you can p/up .2 to .35 seconds

ATTENTION TONY. THE FOLLOWING QUESTION IS FOR YOU:
Why do you say I have to work on the suspension? I haven't had any traction problems, I put new springs in last season... ?

The reason I said that is, I believe most of the et increase will
come from your 60' if you install the new convertor. I remember you saying you replaced the leaf springs,
don't remember you changing your shocks. I think you may have to go with an adjustable shock.
Going from leaving @ 2000rpm to 3500-4000 rpm is gonna be a great shock to you rear wheels/suspension. I noticed with my car leaving harder resulted in a little bounceing. Had to readjust the shocks then it was fine. Again just a thought.

Never mind thenI guess I'll have to wait to get it out to the track to see if I have any traction issues. With my luck, I'll twist one of the tubes off the rear on my first pass.
I'd be happy with a 3 tenth improvement, though.

I think those were resplined.
This is why I have a problem with certian parts like resplined axles and wheel adapters/spacers. I've been there done that and I know they won't hold up, at least not for me.
