Default Performance? I can't drive 55....

I am looking for a package that will keep my 57 Oval at or above 55 on a rural VERY hilly highway. It currently has a stock 1600 DP with Pertronix ignition and a header/QP muffler (ceramic is nice). Will dual Kads alone get me there? This thing is stock geared (for a 1974) and has 195/65's on back. My 1970 with the same package (no kads) had some issues slowing down on the hills around here and it made it less than fun to drive. I wish to avoid that with this one. Just out of curiosity, how quick is a bug with a 1600 and mild performance mods?
Anyone?

The Kadrons will help a lot. Some 1.25 rockers will help also.

It looks like I will need about 90 hp to build a 15 second car. That would make for a spirited fun-to-drive car. Nothing like my 400hp tube chassis, Pro-Street Gremlin was...

I don't know if tire size has anything to do with it, but my the dragon got a freeway flyer tranny in it earlier this year, we have some hills around here, I've deliberatly slowed down at the bottomof a steep one by my house, just so I could drop the pedal and be doing 65+ at the top!
But normal driving, it seems great, I can cruise normal speed 55+with no problem. (1641,weber carb, elec ign. and low profile tires.)

Good to know...1641 hmmm. I may put together a 1641 or 1776 with a spare motor I have. The tire size affects (or effects?)the rear gear ratio and has a large effect (or affect?)on performance. Your shorter tires gives your car a shorter (higher numerically) gear ratio which gives it more torque mulitplication and more 'punch'. It does limit top-end and economy, though.

don't know if you recall the green machine (2tone green/gold flames and packed soundsystem in it) we had in here earlier this year, I think it's in my intro somewhere, any way, he has the 1776, dual carbs, flyer tranny, and bigger wheels, fenders are stuffed. I drove it home ,it would haul a**!!! it had no problem staying constant up the hills either.

I'm sure there's lots of combos to achieve the same results, just a matter of having the right one~

I would build a 1915cc engine if it were me

Or you could just shift down a gear, but still not as fun as a bigger engine

I had almost this exact setup for my '65 before I started cutting it up, the kadrons gave considerable performance inmprovment...I wasnt passing anyone on the freeway, but at least I was keeping up w/ them. The one drawback I would say w/ dual carbs is tuning them, I found kadrons to be very tempermental, I needed to adjust them about every 3 weeks or so, but then I agian I wasnt running a new pair as well...

1641cc with a turbo and dual Dells and 5 lbs boost. My '61 bug did 15.53 @ 89mph in the 1/4.

Bigger isn't always better, you have to make sure it's set up properly.

Sounds like your throttle shaft bushings, were worn out.

I have been running my Kadrons on a 1776, for about 6 yrs now. I really like the performance. My carbs have not been touched, except to change the air filters.
