That is usually a get outta traffic situation and get some speed going, when the inside of your windshield starts fogging up.... It's bad! That's with a 16" electric fan 7blade clutch fan,3 core rad, thermostat restrictor and edelbrock water pump! When I'd get home and it would cool off, those spark plugs got thrown away, electrodes were melted. 12.5:1 comp with iron heads is too high for the street.

What is too high for an old stock engine. In the summer I frequently hit 230, but I have no fan shroud.

230 is pushing it for an old motor, really should be around 200-220 max. You NEED a should, that alone ought to bring the temp down. Don't want to damage what you have.

Mine usually runs at about 195° (the thermostat opening tempture).  I have thin wall heads (supposed to shed heat), aluminum intake, t-sat housing, and finned aluminum valve covers,  And you definitely need a fan shroud.

Brake upgrade time. While this is probably way overkill, I was definitely on the edge of the rear braking capabilities when doing the road coarse thing. Pretty sure this will solve that issue. More photos to come.

Those R nice. Look like 6 piston?

Lot's of posts on the site about the 90's Caprice rear end swap in regard to a somewhat easy way to get set up for rear disc brakes. Is that what you did or is yours a converted original unit? I'd like to keep my unit & the gear ratio but maybe swap out the wheel hubs & axle shafts.

Yes. 6 Piston.

No. I converted from stock drums to a Baer Sport system (12" rotor) on the rear in 2009. The car stops great, but I was blowing through pads and rotors. Hoping upgrading to the 6 piston and 14" rotor does the trick.

Nice job. I really like how they thought out that system, nice & clean & simple.

I did look @ that kit online but maybe I'll just keep the beefy 77 rear drums, LOL

Upgrading the Power Steering as well. I went with a steering gear from Lee Engineering. Had to send them my type II p/s pump as well so they could upgrade the pressure it puts out to 1440psi. This gear has rack and pinion valving and the steering will feel like a new car does. There won't be any more play in the steering wheel, or wandering as you're driving straight down the road.

New Gear:

Decided to paint my remote PSC p/s reservoir so that it would match everything else. Forgot to take a photo before I started, but it was pretty ugly. Sanded it with 600 and then 1500.
74Malibu383 Build - Page 4 Img_2029
74Malibu383 Build - Page 4 Img_2030

Painted it with the same Eastwood Radiator Satin black paint I used before.

Installed. Still need to redo the cap. I'm going to mill off the vent, tap it for a -3 or -4AN fitting, and paint it black.

Also plumbed in a power steering cooler. Sits right next to my transmission cooler attached to the bottom of the intercooler. Sorry for the terrible photo.

I took video on my phone, but it turned out terrible. I'll see what I can do with the video camera. I used some of that VHT 2000 degree paint. We'll see how it holds up.

Power Tour was a success! Lot of miles, but a great time. Met a couple other G3 owners and told them about this site.

Guy from Mother's took a few photos of the car and posted them on their site. Also might be on the cover with a bunch of other cars when Hot Rod does their HRPT issue later this year.
