ERA #783 - with questions
Hello all,
I’ve been lurking for about 2 years now, recently started posting, and am now officially getting into the forums. I’ve had my first deposit on an ERA 427 in since June, with the chassis number set in mid August. I’m looking to do what in my mind is the ideal original 427 S/C, and I know that is very subjective, with the best drive possible. For example, as much as I like the original colors, I’ve had the stereotypical white stripes on dark blue in my head since I was about ten years old. Also, I’m doing an aluminum block FE stroked to 482cid with a 5 speed transmission. Otherwise, it’s mostly based on the comp cars with the rivets, S/C dash w/o glove box, jack pads, etc. You can see a general option list below. ERA #783 Pond 482cid hydraulic roller Tremec TKO600 w/0.64 OD and 3.54 rear ERA dif Competition front brakes Vintage 6-pin Wheels with MT Sportsman S/T Radials 6 inch oil cooler with remote filter Indigo Ink Pearl w/ White (shade TBD) Stripes by CT Custom Car Riveted hood scoop with rivets around front of hood S/C dash w/o glove box Smiths gauges with reverse speedometer Stainless side pipes with ceramic coated primary pipes Powder coated chassis Chrome driver’s side roll bar and chrome jack pads Dual pusher fans with heavy duty fan Sun visors and wind wings Trunk mounted battery Quick release steering wheel Rear fender spats Turkey Pan I have a ton of questions, but here are the two foremost in my mind as trivial as they are. I don’t think there are right answers, so I’m really looking for opinions. 1) I’m planning on spraying the entire interior and trunk with Second Skin Audio Spectrum and Firewall for noise and heat suppression prior to carpet. I’m going to do undercoating/bedliner in the wheel wells. At the time it goes to paint, CT Custom Car can finish the inside of the trunk lid vs. covering it with the felt liner provided by ERA. So, do I have them finish it or do I noise suppress the trunk lid and cover it? Would the noise suppression make much of difference on the trunk lid? Yes, I know the exhaust will drown out most noise while riding. I'm looking for a more solid feel when opening and closing the trunk. 2) This one is a little more controversial in my head and I keep flip flopping between the two options. I want to drive the car year-round. While I do live in FL and it is usually a balmy 80 degrees here, it does get relatively cool here in the winter at times. Also, I may be moving back up north in the next few years depending on employment. I am getting the heater/defroster mostly for state requirements should I move, as I know it doesn’t really do much to keep you warm. That’s why I’m considering installing seat heaters, with the switches integrated into the dash if I can use Lucas switches, otherwise under the dash if I need to use the aftermarket switches. Part of me says it would be nice to have the heaters; the other part says it goes against the idea of the replica and just adds complexity to what is a beautifully simple car. I'd also like to be able to drive it without worrying about the frequent rain here in FL, so the idea of a bare interior vs. removable carpet is a consideration and I wonder if seat heaters would complicate this. OK, I think that is a long enough post for now. thanks for reading, and thanks in advance for your opinions |
You asked for opinions, here are mine based on long-time ownership.

I took my 4 yr old boy for a 10 minute ride and noticed he was kind of quiet for being in the blue car. He said he didn't feel good and he looked worse so I felt his head and leg- both were burning up. These cars are so HOT I can't ever see the need for a heater. Crazy hot! The main reason my mid-late 90s Hi Tech has about a thousand miles on it.

Heater, yes. You don't need it alot but when you do it is a real comfort. Living in AZ and using my heater during the winter months and my wife loves it. I just did an engine swap and I asked her if she wanted to replace the heater with a glove box. "NO way", she said. It would have been alot easier to lose all the hoses but my wife really enjoys the heater in the winter. Believe it or not, it actually snows here sometimes in the winter.

1) Do not install noise suppression. Even the thought of noise suppression on the trunk lid is ridiculous. You will understand how ridiculous it is after you have owned a Cobra for a while.
2) Install a heater. I use it a couple of times a year and it's nice. Do not install seat heaters before you've owned the car for at least one full cold season. 3) You will not be driving your Cobra in the rain. If you do, opt for the soft top and side curtains. You will stay warm with the heater on, believe me, but it's not as much fun as you think it is. |
Seat heaters are cheap. Why not install them now rather than having to worry about pulling the seats apart and wiring them later. I've installed them in my car and I use them a lot. Plus, my girlfriend is much more likely to agree to take the Cobra on a cool night if she knows we can turn on the heater and the seat heaters. I put the aftermarket switches inside the glove box.

I just can't see him using seat warmers in Tampa/St. Pete, even in February... but what the heck.:rolleyes:

Install the seat heaters now, the folks at era ran the lines for me in chasis (dash thru lower door sill behind seats) and put the heaters in the seats. Bob also helped out with the extra wiring I needed to do to add it correctly to the existing ERA electrical wiring.
m-a |
Uhhh, you know that the average high temp in February in Tampa is 72 degrees?

All of your questions are typical of an owner-in-waiting. But once you have owned the car for a few months you will look back and laugh at yourself for having worried and contemplated frivolties such as seat heaters and noise and heat supression. By all means, heat suppression is worth considering, but these cars are LOUD, HOT and UNRULY no matter what you do and you'll be more preoccupied with keeping you and your occupant alive than worrying about whether or not your arse is toasty. It will be.:LOL:
Just my .02c. Jim P.S. Congrats on the car. Can't beat the ERA/FE combo. P.S.S. I just crossed the 1200 mile mark today and officially hate the .64 5th gear. I'd really research that if I were doing it again. |

The issue is the downshifting difference between 4th and 5th. |

Yes, it's a big drop. I have a 3.54 (that's effectively the same as yourss) and the only thing I ever use it for is gentle highway cruising at 2000 RPM (70mph) or a little higher. It really can't be used for road racing. I do like the fact that when I do that though the car is actually pretty darn quiet. The wind noise is more than the pipes. |
Choices...
With the 15" wheels and 3.54 rear, here are your RPM choices for 70MPH.
.64 --- 2000 RPM .82 --- 2600 RPM |
I'm thinking of doing the 3.54 rear with the 0.64 5th because cruising in FL means 80-90mph. Yet again I might be moving back to the NE, where cruising means 70mph, in the next 2-3 years. I've been considering the 0.82, and if I go with it then the question is whether to go with a the 3.54 or the 3.31 rear. Gear ratios are here:
http://www.erareplicas.com/427man/tr...ring/index.htm For the seat heaters, my wife enthusiastically votes yes we should have them. Even for 50 degree weather. So that might swing the vote. Regarding the noise suppression, it isn't for actual sound, but more the vibration sense of the car. I like being able to knock on an aluminum panel and have it sound dead. Then again, is may be not be worth it for that either. What I'd really like to see is if the Firewall helps with cabin temperature. |

I do like the way that torquey 294S cam takes over at 2k/70 mph mark and just pulls and pulls and pulls. And by the way, I pounded the absolute snot out of it today for 200 miles with the final timing and carb settings you and I discussed and with that new fan, it never got over 90*C water and 105*C oil. Runs great. |

It sounds like you're on the right track. Don't sweat the small stuff. The insulation you speak of will probably be moot. Do install the heater/defroster and maybe the seat heaters. I'd go with the 3:50 rear with the .82 OD. When you're spending the kind of money you are who gives a $hit about a couple of mpg...you just want the engine to breath. Good luck.
