Got the engine & transaxle into the car, bolted up at the back, and ready to fabricate a few minor parts to make the new forward crossmember mate to the body. The forward crossmember was bought from Speedway Motors in Lincoln Nebraska for a grand total of $58 to my door (http://www.speedwaymotors.com/). The crossmember clears the shift linkage just fine.

Another update on my Buick V6/914 conversion.
I did my conversion last spring and summer and got the 914 up and running but ran into a little problem with vibration at 2000 RPM. The flywheel wasn’t balanced correctly to the internals of the engine. When I built/rebuilt the engine it was as stock with the exception of a mild cam, Edelbrock intake manifold, 390 cfm Holley four barrel carb, Sanderson headers, and MSD billet distributor and ignition box. The conversion was pretty straight forward once all the parts and pieces got into place. But because of the vibration I decided to go ahead and drive it as is while I build another engine, then I'll do a weekend swap of the new engine for the current engine. The engine that’s currently in my 914 is a 3.8 liter Buick V6 and the new engine I’m building is a 4.1 liter Buick V6, which was in production for only for 4 years and I was lucky enough to find a good motor with no block or head cracks. This time around I found a machinist who is very familiar with the Buick V6 and together we’re doing it right. By right I mean align hone the mains, deck the block to match the deck height of the new piston/rod configuration, and bore the block (with torque plates in place), Manley stainless valves, JE forged 9 ½ : 1 pistons, completely rebuilt connecting rods bushed for free floated pins, and the addition of ARP rod bolts. I also added an Isky cam of .470” lift/270 duration, Isky lifters, valve springs and retainers, combustion chambers CC’d to equal volume (45cc, talk about tiny combustion chambers volumes for a 4" bore!), and a bunch of other stuff. All the machine work on the engine is complete and I’m now waiting on a new flywheel from Kennedy Engineering so the whole assembly can be balanced correctly. I find the 3.8 liter V6 in the 914 to be impressive in its current configuration in terms of power, so this new 4.1 liter should be REALLY impressive. It’ll be a couple of months yet before I do the engine swap out due to cold ass weather here in the northwest and still waiting on a few parts to come in. I’ll update this again when the swap is complete. Oh yeah, this (IMG:http://www.914world.com/bbs2/html/emoticons/stromberg.gif) is gonna be good! |
