Some Camaro questions.

[Ju1cyJ]

First of all how much does a stock big block 67 RS/SS Camaro weigh (the one with a 396)?

Also, how much horsepower can the rear take? Did the good ones come stock with a 12 bolt posi rear? Is the frame narrow enough, that when tubbing you do not have to narrow the frame, only tub the body?
Did all the auto camaros from that first generation have a TH400? What would a 67' Camaro with good traction run with 5:1 Lb:HP ratio?

Thanks guys, I know you can come up with some answers to these q's =).

I would imagine a BB camaro would be around 3400-3500 depending on equipment.

Depends on the rear. The 454 LS-6 put out 450HP and the rear was fine and since all the 12 bolts are the same I would guess 450HP+ would be a good figure.

Did the good one come with a 12 bolt? Good ones what?

It depends on how wide the tires are going to be. If you want 30X12.5 you might get away with just adding a few inches to the wheel well. You want some 33X16 mickeys you will need to do the frame,wheel wells, and axles.

most small blocks had either a T350 or a Power glide.

A 396 camaro with all the right parts,traction,suspension,tuning and what not should do low 13s, high 12s I would imagine. It all depends on how everything works together.

Just adding a BB to a car will pick up some tenths but you wil also have traction problems. Camaros have no sub frame so you would need sub frame connectors if you serious about racing.

What will you do with the car? race only/street/street & strip?

The car will be used basically as a weekend warrior with some strip time and some street time.

The plan is to buy a already semi built 67' roller, that is already tubbed and a good sub frame, etc.. Then drop in a drivetrain of my choice, which will likely consist of 600-650 HP. I wanted to know some other specs to see how built the car had to be to take the kind of HP I want to throw at it. I definetly want to run big Mickey's, so it sounds like a major tubbing is necessary.

In case you were curious, I plan on a 509, or a 540 Merlin crate motor with a built TH400 from Pheonix Trans.

600 horse the stock rear suspension will not take, you need to look at the frame/spring connections
they will rip out if they are getting rusted,
look here at camaros.net for lotsa info
i have a '67 4 speed with a 427 in it, i have added frame rail connectors,and 3 leaf Hotchkis brand rear springs.the stock monoleafs are Not good for traction, you should at the least for drag racing on occasion,get the cal-trac traction bar/links, they are very very good,worth the $$
if your car has a 12 bolt fine.,if not there are other options,like '72-78 8.5 nova 10 bolt rear,or ford 9 inch...
most important,if you are going to go fast put disc brakes up front First,they will prob save your life,the stock front drums are ok for about 300 hp max....

I could i get a bolt on rear clip from a drag shop around here that would prolly handle around 1000 horse, it has a Ford 9" (of course) and they would make it as narrow as I want it (i would have to give them my exact tire specs). But it is a little pricy, I am curious as to how much you spent on u're rear end, PM me if you do not want to say on the forum.

Another idea I have is to put a 427 small block in it that gets 540 HP, do you think that would be faster than a big block with 600 HP?

P.S. Disc brakes up front, not even in question, a necessity!!

1. Car weighs less than 3500lbs.
2. All big blocks came with TH400's behind them if automatic. Small blocks usually had a TH350 or Glide.
3. You can get a 14x32" slick in a stock wheel well by simply widening it; e.g. stretching it out by a baseball bat.
4. Get a 9" rear end. Put coil overs on when you tub. Ladder bars. It will work fine.
5. With one of those engines, the car should run in the 10's.
6. A 427 small block with 540 hp won't be as fast as the big block with 650.
7. I spent 1000 in labor to have my truck tubbed, plus parts. Well worth it. Probably will be a bit more for your car, since a truck is easier to do.
8. Again, the 12 bolt ain't going to cut it if you start putting serious HP to it. Go to the drag strip and you'll be hard pressed to find anything other than 9" Fords and Dana 60's.
9. Always better to buy a rolling chassis than to build one. Always.
10. I have a 427 that's .072" over, 14-1, roller cam, rect. port heads, etc, etc, that makes around 640 hp that I might sell for the right price. Has about 50-60 1/8 mile runs, scheduled to be freshened at 150 runs.

i have a 10 bolt 3:31 posi in the car,i street drive it,took it to the track a couple times,
my 60 foot times are 2.4-2.7 sec,,,,
cant hook up,i am running 245/60r15 on the rear with wheel vintiques 15x8 rallye wheels; with the 5 inch backspace, i think that 275/60r15 will fit in the stock wheel well,on these rims/offset.
The "stock" vette style 15x8 wheels have a 4 1/4 inch backspace,and the tires are too close to the wheel well lip.Be careful,as the tires get hit by the wheel well,when bottoming out {hitting bad bumps etc}
Go to the local drag strip,and talk to the people running '67,68 camaros,ask them for suspension hints,
go to the linked camaros .net site and search race,rear end etc
linked hope it works,,
the main problem is $$$ LOL
