'69 230 build w/LQ4 swap - Page 14 - PeachParts Mercedes-Benz Forum

Just throwing this out there:
That chassis never held a V8 from MB. Inline 6 was the most powerful stock plant. I am sure someone may have done a swap, but I never saw a 6.3 in a 114/115. So yeah, I def undersold the power boost from the best stock engine to your new one. You'll easily have 3 times the power, and probably closer to 4 times at the wheels I bet.

Sorry for my oversimplification. Thanks for correcting me. I was mainly referring to the size of the engine bay that it could fit a V-8. Even though a different numbered chassis the engine bays are very similar.

I have pretty much finished the engine bay. Brought the undercoating up to the finish paint, touched up the paint on the crossmember, installed the motor mounts, repainted and installed the brake booster and wiper motor, installed the hood seal, and installed a carrier bearing to support the steering shaft through the firewall. Hoping the engine parts get out of the machine shop this week so I can assemble!

Very nice! I think you're going to have one heck of a nice, award-winning car when done. The attention to detail is incredible.

Beautiful work! Very excited to see the finished product.

Tomguy, thanks. Don't know about award winning though!

Next up is new brake lines, because the front passenger side will fun across the firewall, and modify the Chevy gas pedal (drive by wire) to fit since it will bolt through the firewall.

300, thanks for the positive comment! I'm anxious to see it done too, but enjoying the journey.

Any updates on this?

Coasttocoast · #**204** 11-05-2016, 12:53 AM

Sorry for neglecting the build lately. I just picked up the engine, block, heads, rotating assembly from the machine shop today, and the trans from rebuild last week.

I have been porting the heads, exhaust manifolds and intake manifold (well over 50 hours) lately. Details on LS1tech.

It took the machine shop about 3 weeks longer than I had hoped for. But I did get some work done on the brake lines (replacing all) and tried my hand at welding up the stainless steel crossover for the exhaust.

Hopefully by next weekend I should have the engine assembly/trans ready to put back in, at which time I'll start posting updates here again.

Coasttocoast · #**205** 11-14-2016, 12:37 AM

I took advantage of the 3 day weekend and finished the assembly of the engine, bolted up the rebuilt trans, and bolted it back into the car.

Now that I'm mostly through with the engine building stage I'll be posting the rest of the project progress here again.

Look Ma, no hands!

This afternoon I completed the last piece of the trans mount. Pretty simple piece. Made from the same 1/4" x 2" plate as the floor pan brace, V cut, bent and welded. Then 2ea 5/16" bolts on each side to the floor pan/trans tunnel brace/support. I made the mount about 3/16" narrow so that tightening puts tension on the braces.

As I did before and after on the crossmember, as to measuring sag with the engine weight, I did on the trans mount. Zero sag. I'm really surprised since the trans mount is carrying a good amount of weight. The motor mounts are between the first and second row of cylinders, so 3/4 of the weight of the engine and the transmission is on the trans mount.

Took the measurement between the transmission yoke and the diff to get the driveshaft made. I used a local company for my jeep project with great success, so I'll drop the related hard parts off at the shop tomorrow.

That engine looks like it was meant to fit there. Granted, it's because you did a good job making it look that way, but it does look very nice! I am sure some purists would be upset, but with a large volume of production, there are plenty of originals left for them

Thanks for the compliments!

Yes, I'm sure that a few are not happy with the thought of an alien engine sitting in this bay. And of course your right, this car is not an endangered species. But to be politically sensitive is why I posted the engine in build on LS1tech.

Continuing to make progress, the custom drive shaft was completed today. 3" x 083 wall tube. They did a beautiful job, I supplied the yokes and u-joints and the they also assembled it all.

Tomorrow I have a full day of odds and ends and lots of new parts arrived to install.

Today I completed the water pump, front accessory drive system, exhaust manifolds, coil packs, spark plugs and wires.

The extra think 2 1/2" stainless steel exhaust tubing and bends I ordered arrived today. I'm going dual exhaust, X-pipe, a pair of Magnaflow oval mufflers located in the area under the rear seats, then a pair of 4" round Magnaflow mufflers located on each side of the fuel tank under the trunk, then adding a second opening in the rear valance so the pair will exit balanced under the bumper.

My planned path should be able to be accomplished with these standard size pre-bent tubes, with the exception of the pipe coming off of the manifolds. There I need to cut out about 26* out of a 90* bend. My V cut leaves about 1" of the original pipe.

Then a quick tack after cutting to check fitment. The bend looks like it was always this angle.

After a couple fine adjustments welded up. Don't laugh at my welding ability. Besides being a novice I'm using a 110 volt welder with gasless stainless wire.

A little clean up and should be fine for under the car.

I ordered a 22 circuit Kwik Wire wire harness to rewire the car and the Vintage Air Magnum IV HVAC unit and hose kit today. I need these on hand to know how to start planning hoses and wiring though the engine bay. I really want to keep the engine bay clean, but no way around the pair of lines between the transmission and oil cooler, pair of heater lines and par of AC lines that need to run down the passenger side. This isn't going to be a show car or anything, but needs to be clean and serviceable.
