1968 oldmobile Delmont 88 convertible.. couple of questions..
Hello every! Just got my very first Olds classic.. and im very happy with it..
But i got a few question..
1. the convertible top works but when your raising it it stops after about 20-30 seconds..mid way up when you trying to close it,, you let it sit for 10-20 seconds and it works again.. tops brand new with a rebuilt pump..
the kid i got it from said that the resistor on the pump heats up and thats why it does it..
what resistor? how do i replace it? kid said it was on the pump.. for the top its self..
and 2.. car came with a street dominator intake and a eldle broc carb..
my question is this..
when i floor it in park it revs right up and is stupid loud..
but when driving it doesn't seem to get that same peppy response as in park and just revving it up.. doesn't seem like the carb is really getting that secondary ooomf when you floor it..
any ideas would be awesome.. thanks.

That intake is designed for an rpm range that the car can't handle.
They were never meant for low end power, and because that car is so heavy, and that you'll never find lower than a 3.08:1 axle ratio, it will struggle off the line every time. I tried the very same thing with my car, I was happier with a performer, or even the stock intake it had before.
Normally a guy would use an intake like that with deep gears, and a big stall converter.

Is this a 350 or 455?
It makes a big difference. As 68Delta88 mentioned, the Street Dominator is a single-plane design which maximizes top-end power at the expense of low-end torque. Now a 455 can afford to give up a little low RPM grunt without feeling anemic, but the 350 is another story. A single plane intake and high-performance cam will kill the throttle response of a 350 in a big heavy car with automatic trans and the (350) Delmont's standard 2.78:1 rear gearing.
If you have a 350, you'd be better off with a factory intake and a Quadrajet.
If you have a 455, the Street Dominator intake can work OK if the rest of the combo is well-matched, but you'd still be better off with the Edelbrock Performer.

I like the way the fan shroud is grounded. 
And it's always good to have TWO car alarms, in case one doesn't go off for no reason in the middle of the night.
With all that "attention to detail," it's interesting that the PO left the voltage regulator in place when he converted to an internally regulated alternator.
By the way, I'd solder those crimped connections to the alternator if I were you.

Replacements are available from many convertible top suppliers such as these:

That's a convertible top "boot cover" or just boot. The car came with it originally.
