Broomba 70 Lemans Resto-Mod

I wish, but sadly no. This is something I've always wanted to do so I'm being very meticulous. The other thing is, that I want to do all of the work that I can do or that I can learn to do. For example, right now, I'm weighing the alternatives of just coughing up the money (about $700, only because I'm friends with the mechanic) to rebuild the TH 350 with a shift kit, "beefier" clutches, and such or get some books and videos and learn to do it myself.

Currently, I'm learning that POR 15 is about as good as getting a tattoo.

I haven't even started on the interior or body. This is going to take a long, long time, but I'm having a lot of fun, so that's a good thing.
 
on that transmission you should also investigate if it involves purchasing of tools that you would only use once.
 
I hear ya. I'm pretty cheap. For example, I had to buy a 25 ft roll of brake line when I only needed 10 ft or so. The rest went on ebay. Somebody else only needed 10 ft or so too and it was gone.

I've rented some things, borrowed some things and had to buy some things that I sold on ebay to get some of my money back.

I don't know how I would have done this project when I was a youngster back in the day without the internet.
 
A comment on you sway bar hookup. If you are using factory style rubber bushings on the bar to the frame do not tighten them until the car is on the ground at it's normal ride height.
 
some questions related to your cam choice
1. What rear end ratio do you have
2. Are you using a non-stock stall speed torque converter?
3. What ratio rocker arms are you using?
______________________________
 
I'll be replacing the rear-end when I get back that far. Currently it just has the 10 bolt stock, single tire fryer. Not sure what that ratio is.

I'll be putting a 3500 stall converter in. Haven't decided on a brand yet.

For now, I'm just using the 1.5:1 stock rockers. That's what the other builds I looked at had used. I can always up it a little if I feel I need more lope, but I don't want an extremely aggressive cam ratio. I won't be doing any serious drag racing.
 
very nice, what are you going to use for an intake manifold?
______________________________
 
I forgot all about the intake. For now, I've also refinished the stock cast iron intake. In the future, I plan to get an Edelbrock Performer RPM if it will fit under my hood with the ram I've designed. If not then I'll get the Torker II that's a little lower profile.

I have an Edelbrock carb that's their 750 CFM model...I think, but would like to get a new 800 when I get the new intake. I had a Holley Double Pumper in the past and since I'm at a little above a mile in altitude here at the house, it seemed to need constant adjustment. Maybe it was just my unit or me. The Edelbrock seems much simpler.

I mentioned the air ram. Before tear down, I took some measurements and I believe that if I use an electric fan on the radiator, I'll have enough room to fabricate a couple of air scoops behind the holes in the lower valance and then run the lines to the carb. I don't know if it will make any difference but I'm going to give it a try.

I added a pic of the refinished intake to the blog.
 
I've had quite the education. I rebuilt the TH 350 tranny to stage 2 specs and completed the front brake lines. Now I'm just waiting on a 2500 torque converter that I'm having built and then the engine can go back in.

it's often been said the auto trani is the most complicated component of a car and I'm amazed you tackled this task.
 
I've put rearends , motors and 1 Kia Rio standard trans together but never an automatic................ x's 2 what Mel said.;)

ATI has manuals that are great as I've heard, Monster Transmission gives you an instruction manual and tools with their rebuild kits also.

Yet to tackle one on my own.............put on the bucket list.:)

Rebuilding the tranny was a little stressful at first and I didn't just dive in and try to figure it out. I bought a dvd from a guy on ebay. Seller name is "f-bodies_inc". He does an amazing job of describing every little detail of the tear down and reassembly with a few tips and tricks. I'm fairly confident in the end result. Time will tell.

Anyway, I connected the engine to the tranny and stabbed it back in last week-end. Piece of cake.

I picked up what I think is a little treasure yesterday. A guy bought this 8.2 BOP posi out of a '68 GTO to put in his Nova then decided he would be better off with a 12 bolt since he mostly does 1/4 mile trips, so I bought it from him, complete drum to drum for $200. I pulled the cover and it looked good. The gears were all clean, even, and seemed solid.

It wasn't original to the GTO. The only codes I see on it are "9795082" on the diff case and "284 5f" on the back of the driver side tube. I've only found 5f in one place and that was for a "69 Grand Prix, medium duty 4 pinion" When I counted the teeth and did the math it came up to a gear ratio of 3.2 and change which was the same for that Grand Prix's 3.23.

Anyway, not my dream diff, but I couldn't beat the price and it's better than the One Tire Fryer, I currently have.
 
Looking back I see you have a 466 CID monster. Thats probably produces tons of torque and with the high stall and the 3.23 you may be quite happy with the combo.
 
That's what I thought about the gear ratio too. Not only is it stroked, but I gapped the rings for nitrous for when I add it someday. I think with a really low ratio I would have just burned the tires off and maxed the RPM's too soon. I won't do any serious drag racing anyway. I was looking for a 12 bolt or even an 8.5" 10 bolt, but for $200 if it blows up, I'm not out much.
