Re: H-I-J '76 Nova re-fit.
 

Todd, I don't know whether you plan for her to run H, I, or J Stock, but I guess one consideration would be how often you think your daughter would be likely to come up against a stick car in her class. It looks like you've done a lot of high-quality work there- I see no reason the car shouldn't run under index. And if heads-up races are unlikely, then the rear brakes may not matter from a performance perspective.

From a safety perspective, disc brakes would be better. Especially when racing with breakout rules.

Most automotive drum brakes are self-energizing, so the actual braking force is progressive, rather than linear. A light push on the pedal would result in almost no braking force in the rear, a moderate push on the brake pedal would result in moderate braking force in the rear, and a hard push on the brake pedal may result in rear brake lockup. I'm sure we've all driven a car from the '60s with power 4-wheel drum brakes- you know this feeling, where light pedal pressure does nothing, moderate brake pedal pressure gives you the braking force that you're aiming for, and heavy brake pedal pressure locks up the wheels unexpectedly.

This is compounded with the vehicle's weight transfer under braking- the harder the driver brakes, the more weight is transferred to the front- and yet the rear brake forces ramp up disproportionate to the actual brake pedal pressure, while the front brakes are responding in a linear fashion.

Disc brakes are much less likely to lock up, because they are much more linear- the actual braking force is directly proportional to the brake pedal pressure. This makes it much easier to modulate the brakes- they are more forgiving.

And with a properly set-up disc/disc set-up, the braking forces stay proportionally balanced (all things being equal), which helps to diminish rear wheel lockup as weight is transferred to the front under braking, much more so than a comparable disc/drum arrangement.

I just did the brake swap on my 79 Camaro. I had iron drums on the rear and it saved 19 lbs total weight and 14 lbs rotating. I used the Strange Eng kit. If your shock set-up is like the Camaro, order an extra right side caliper bracket so you can flip the left side caliper to the front for shock clearance. I changed the front and rear at the same time and picked up .03 nearest I can figure.

Re: H-I-J '76 Nova re-fit.
 

Thanks for all the brake info guys!

Re: H-I-J '76 Nova re-fit.
 

WE'RE BACK! After two weeks gone and a week of work it'll be nice to get a few things done to the car this weekend.

Re: H-I-J '76 Nova re-fit.
 

Didn't get a whole lot done this weekend. Pulled the axles and backing plates off the rear, moved a bunch of stuff and got the tools sorted. Biggest thing was parts, we had to sit down and make a parts list so I can get them ordered up this week so the work can commence. A bit of a slow start, but a start none the less.

Re: H-I-J '76 Nova re-fit.
 

Mails here! Random cooling system pieces and enough to get a start on the fuel system.

Fragola & aeromotive fittings.... Baller!!

Re: H-I-J '76 Nova re-fit.
 

Just for that I'm stealing your regulator mounting bracket idea! :D:D:D

More mail fun... and a -8 removal -10 install

Re: H-I-J '76 Nova re-fit.
 

Help! The pump and lines were under a factory floor that would cover the original jack and such, the tank was partially under the floor with a hinged lid over the top portion of the tank. If I just put a firewall up will it be legal without the pump and tank covered? If I'm reading the rules correctly it should be ok with tank, pump, filters and lines mounted inside on the floor behind the firewall uncovered.

Re: H-I-J '76 Nova re-fit.
 

There are many SS cars with the same tank and pump set up as you propose. So yes, you will be good.

Re: H-I-J '76 Nova re-fit.
 

Because you have a Hatchback, the back section needs to be " a separate compartment "

Re: H-I-J '76 Nova re-fit.
 

Todd I would immediately call NHRA tech and ask them how to do it. You might tell them your proposal and run it by them see if they will accept it otherwise look at late model firebirds/ camaris/mustangs for ideas on what others have done and is accepted

Re: H-I-J '76 Nova re-fit.
 

Yes sir, the plan is to have the firewall approximately where the carpet stops at the floor and go on up to seal at the hatch.

Re: H-I-J '76 Nova re-fit.
 

Perfect, thanks!

Re: H-I-J '76 Nova re-fit.
 

Feel like were back on track and getting a plan today. Laying out the fuel stuff and making bracket templates. Getting a better cooling system plan, a little underhood wiring and trying to figure out my ballast (legally).

Re: H-I-J '76 Nova re-fit.
 

Looks like a double fuel filter before and after the tank why???

Re: H-I-J '76 Nova re-fit.
 

I've always run Aeromotive 100 micron pre and 40 micron post filters, catches trash from the tank and if the pump fails doesn't get into the carb or injectors. These filters have 60 square inches of filtering and full flow capabilities of 3000 hp. I've always had good luck with them.

Re: H-I-J '76 Nova re-fit.
 

Ok was just wondering about fuel flow

Re: H-I-J '76 Nova re-fit.
 

SUNDAY SUNDAY SUNDAY brought more wiring. Ordering new side marker pigtails but other than those got the underhood harness complete. Finishing up the battery cables for the charging lugs. Checking some options for underhood LED lights and starting on brackets for those. Still measuring and planning out weight tanks for the permanent weight, lot of weight going in due to the 100lb driver. Should have a good bit of parts coming in this week so hoping for a productive weekend coming up.

Great progress, Todd. Clean, tidy and well thought out. :) -Al

Re: H-I-J '76 Nova re-fit.
 

What battery is that?? If you think about it could you get me the dimensions?

Re: H-I-J '76 Nova re-fit.
 

That's a Deka same thing as a Braille they make them for Braille

Re: H-I-J '76 Nova re-fit.
 

Thank you Al.

Re: H-I-J '76 Nova re-fit.
 

I wasn't so sure of the battery, I got the one that was in the car and a new spare that came with. The old one seemed to do fine at the track though.

Re: H-I-J '76 Nova re-fit.
 

We're so far behind here we gotta try to step up the "during the week shop time" so Autumn dropped the radiator to a buddy to get it welded on and I stopped at the local candy store to pick up some stainless braided (with a woven nylon cover) fuel line and a bit of -20 to try.

Re: H-I-J '76 Nova re-fit.
 

ETX18L is usually a battery grouping used for motorcycles,scooters and atv's ! I guess if it works for you, run with it. Nice and light that is for sure.

Re: H-I-J '76 Nova re-fit.
 

That's exactly what it is... a motorcycle battery. Worked fine the little bit we did actually use it.

Re: H-I-J '76 Nova re-fit.
 

Half the price of a comparable Braille... https://www.braillebattery.com/index...atteries/b2317 If it lasts and does the job I would run it as well.

Re: H-I-J '76 Nova re-fit.
 

When your wrench is -20 but your fitting is -21 :rolleyes::rolleyes::rolleyes:

Re: H-I-J '76 Nova re-fit.
 

Do want you want with the battery options but 3rd round Sunday I had to drive around a guy in the lanes because his unit would not crank over. Certainly he was happy to miss the round. Go for big, lots of cranking amps, and reserve. Money well spent.

Re: H-I-J '76 Nova re-fit.
 

I will second that.....When that little girl starts going rounds (and she will) these mini battery’s will disappoint at the worst possible time....

Re: H-I-J '76 Nova re-fit.
 

Thank you guys, point taken.

Re: H-I-J '76 Nova re-fit.
 

This is the minimum we run in the E/SA Camaro Todd... https://www.braillebattery.com/index...atteries/b3121

Still going strong after three seasons and it is still pretty light. We do run an alternator and charge between runs. The 17 is kind of iffy.

Re: H-I-J '76 Nova re-fit.
 

Thanks Rich, I have a Braille store about 1/2 mile away, I'll stop in and look into that battery. For now, I'll put the new one we have in then replace it with the Braille later.

Re: H-I-J '76 Nova re-fit.
 

Aside from the light weight of a Lithium Ion battery they can be fully recharged quickly like in 30 minutes or so as opposed to a lead acid or AGM battery that needs considerably more time.
In addition to their weight savings Lithium batteries also can be mounted in virtually any position, and due to their size take up very little space wherever positioned

Yes cost is a factor but the advantages I feel out weigh the disadvantages when compared to the other types of batteries you might be considering--FED 387

Now the price seems pure insanity but reading it's capabilities as far as how long it holds a charge is really unbelievable.

Re: H-I-J '76 Nova re-fit.
 

I'd sooner be gut shot than spend that much on a battery lol! :eek: :p

Re: H-I-J '76 Nova re-fit.
 

Not sure if 3 batterys or head work. :D:D:D
