Getting closer... going with a "Johnny Joint" on the upper mount. Should allow for more movement and less binding of the rear end.

My friend brought the housing over this week and we put it up in the car. Took a TON of measurements, and tacked some pieces on. He's finishing up all the welding today (hopefully), but he sent me some photos. Getting pretty excited.

Bruiser - Getting closer man. I'll let you know when you can come grab the 10 Bolt.

Good deal! It's all good! I'm looking to gather some parts myself before I install the rear end. I'm running a 454 with small block springs in the front and 215/60-15 tires, In the rear I have stock springs with 31x10.50-15 tires and obviously the rear end sits very high. So I'm looking for some 3 inch drop rear springs, and still researching the u-joint situation.

Couple more rear end photos. Axles were ordered Monday, so I hope to get everything back by this weekend.

I had a stock 4l80e behind the 540 but after adding the f-2 I'd stepped into it about 6 different times and noticed a bit of slippage between 2&3 so I didn't pressure it anymore. I found a 2003 trans and put alot of the upgrades into it and have not had any problems, liken what your doing good luck !

Anyway, some parts came in!
- 3rd member from Currie
- Full floater 6P kit from Baer (Disregard the ebrake adapters on the right. Those are for another build he is doing)

Dropped my old rear end and all the parts off at my friend's shop. Hoping to have a new housing by the end of the week!

why a floater ?

On the few road courses/auto-crossing events I have been a part of, I've experienced a little bit of pad knock back. I figured as long as I was having a custom housing built, why not go all the way. Plus, it's definitely a little stronger than a standard housing.

Not wanting to take anything away from "Malibu383" .

I wanted to understand as well. This is what I found.

Well there is your problem. Stop making turns. Real race cars go straight. Laughing

Thanks for the link... That is the exact setup I went with.

HA! I may not be the fastest in a straight line, or the fastest through the turns, but I sure do have fun!

Intercooler tubing is complete! A friend did the work for me. Can't decide what to do with the tubing though. Thought about brushing it and clear powder coating it.

You can also see that my radiator hose didn't fit, so now I have a custom stainless one. Thinking about painting that black... don't want it to be the focal point.

Thoughts?

That really looks sweet. Nice work.

x2. That's a work of art!

by Joe73 Fri Mar 11, 2016 6:46 pm

You might want to ask the powder coated about the clear. I wanted to clear my intake but was told that it would probably yellow slightly over time. So I went with their silver which is a match for argent silver .

by testpilot61 Fri Mar 11, 2016 7:23 pm

Man you have to be so excited with all the progress your making. I bet you do have a blast when you get on the go pedal. Anxious to see your results when your ride is all together.

I have a 76 Malibu that I have owned since new with a great deal of updates. I'm quite interested in the closure you have in front of the radiator. Have always wanted to close up this gap. Did you build the panel? It sure cleans up that open area very nicely.

Understand not wanting the stainless radiator to be the focal point but with all the impressive work with the tubing I would consider leaving it as built. Seems a shame to hid such a nice custom radiator.

Congrats for a job well done.

Bryan Joe is right the heat from the Motor will yellow the Clear powder coat, I do that here and have had to redo it when a customer wanted it, I told him it would but still wanted it done 3 months later he went with silver and done.

by Joe73 Fri Mar 11, 2016 8:30 pm

You can check out the silver color on my intake in my build thread in my Sig. Its the pic with the scattershield.

by bigredlaguna Wed Mar 16, 2016 12:50 am

Simply beautiful, Bryan. I would leave the stainless radiator hose alone. The natural look of the tubing along with the lightening holes in the radiator support give it the look of something seen in an aircraft engine.

My $0.02- FWIW, I would leave it alone except for maybe painting the pipe for the radiator. I can't decide if the red from your valve covers would look cool or maybe the same black you're using on the other engine bay parts?

That is really awesome looking. I had the same thought with the red color but I think it might get too busy with more parts colored red. I think the radiator pipe/hose would look best flat black and leave the pipe color or silver for the turbo piping.

Joe/Anthony - Thanks for the heads up on the clear powder. Definitely don't want it to yellow.

Everyone else - Thanks for the kudos and opinions. I appreciate it!

I think for the time being, I'm just going to leave it as is and stare at it for a while. I'll figure something out before power tour this year....

Update - I have an appointment at the dyno on Wednesday. If all goes well, I'll post up some numbers. I just can't wait to drive it!!!! I was able to take it out for a little spin around the block. Never went more than 47% throttle according to the logs, and there was a lot of tire spinning. So.... drag radials are going back on before the tuning!

Jerry - Thank you. I made them out of cardboard and then had someone make them out of metal for me. He's super talented that's for sure. Once I was done, they were worth about 10 degrees of cooler highway temperatures in the Arizona summer...

by 74Malibu383 Thu Mar 24, 2016 12:12 pm

Well, good news, bad news, good news.... I think...

Took the car to the dyno yesterday and made a few pulls. It made 630ftlb of touque at 3000rpm, but then just fell off. Turns out the little D1SC blower just can't produce enough air for the 572 and is now acting as a restriction. It could only muster 1psi of boost and I have the smallest pulley Procharger offers. That's just not going to work. I was able to call a friend and get a good deal on a F1R Procharger though, so I'll be picking that up today. If I get lucky, I won't have to rework the intercooler tubing. But that may be a long shot.

I did drive it a little bit though, and that 630ftlbs of torque is scary fast! Even with the 3.50 gears, it feels like a rocket ship. Can't wait for the bigger blower to make some real power!
