Carb, 383 Swapped 92 Caprice

So my block got blowed up from sitting through 5 winters with watered down antifreeze. Since the TBI sucks ass anyway, I'm going with a carb on this motor. The block has been cleared for the 400 crank but nothing has been built yet, I'm hoping to be testing in the engine stand by the weekend. The order from Summit was crazy huge but most of the parts have been free. The block was donated, pistons, rods and crank are from the last motor so all said and done I should be under 2 grand.

While I waited for the engine parts I got busy with other stuffs like replacing the SStreetlights with cheap Asian built crap that was cheaper than 20 year old OEM lights.



Painted the gauge bezel and got some new gauges to put on the A-pillar.





Pulled the wiring harness out and started weeding out the things I'm not going to use. I've got it down to; speed sensor, wipers, voltage regulator, head temp sensor, oil pressure sensor, fuel pump and A/C and the other transmission plug that I think is the gear selector switch?





Plugged up the old o2 sensor bung too, still working on ideas for plugging the MAP sensor hole.

After pondering it for a while, decided to use water weld on the MAP hole.



I got the gauge senders through the firewall, I had to remove the parking brake pedal assembly and widen the slot that was conveniently located right where I needed a hole. Got the pillar pod on and everything is ready to be wired up.



The motor is finally gonna get built this weekend!

Today I'll be in the shop all day building the motor, picked up the new block from the machine shop on Friday and it ended up costing $1000! It used to be $10 a hole for boring and now it's $25 but I really can't complain with all the stuff I've been getting for free. I had them thread the lifter galley plugs.



The pistons were in great shape.



I'll be using one-peice pushrods this time, these were free. The only bolts that will be re-used are the head bolts but the rest are new and were donated.



The new cam is really promising, I like the thought of variable valve duration too.

I didn't quite get it finished yesterday but I did get everything up to the rockers on. Incredibly, a half inch of lift isn't too much for the original LO5 rockers. I had to modify the throttle linkage plate with a vice and drill press but it fits perfectly on the new manifold.

The crank scraper was free, I had to cut out the oil pan baffles for it to fit.



Got the manifold and covers all mocked up for fitment of the throttle linkage. There's no rear crossover so I'm going to have to run a new heater core hose up to the front.



This is basically how it will look though, the valve covers will be gloss black with the tops of the fins buffed. These are the real deal Mickey's not reproductions.

Had it on the engine stand Monday night and fired right up. I'm gonna use black plug wires in the car to match the distributor and the valve covers, they look so good black. I gotta re-paint the headers too, they have gotten nasty over the years.



I ordered Z06 rims and adapters today, not really excited to see how they look tucked in the skirt though. This is the style I'm talking about, I'm not a big fan of the newer ones
