V6 FEVER, ALUMINUM ENGINE

[Jonathan S]

I know Russell did the aluminum head/plenum swap but I want an aluminum block too. Any suggestions for a good 3.4L aluminum block to compliment aluminum heads. I got 70k on my 3.4L right now and I'm gonna live with it until it gives me problems. How much weight would be shed from swapping in a totally aluminum v6 in there? And don't even think about saying oh just go for a v8. I want a sick v6.

damn 70k, its gonna be a while till it gives you problems.

im at 158k, third or fourth owner. everything seems stock from 94, and no problems.

i want to do the same thing but i cant justify the cost when my engine is still running fine.

on the 3.8l the whole intake is aluminum

How sick do you want? GM has, or had an aluminum Bow Tie 2.8 block just oooooooooozing to be raced.

10051141 Bow Tie Aluminum Block
This heavy-duty aluminum block is 47 pounds lighter than a production rear-wheel-drive cast iron block. It has extra-thick cylinder walls with dry nodular iron sleeves. The head bolt bosses are reinforced to improve head gasket sealing. This block has wider main bearing bulkheads than a production cylinder case; four-bolt caps are installed on the two intermediate main bearings. These billet steel main caps have splayed outer bolts that provide additional bearing support. The aluminum Bow Tie V6/60º block features a revised lubrication system. The "priority main feed" oiling is similar to a Chevrolet small-block V8, with three oil galleries above the camshaft; production V6/60º blocks have only two oil galleries. Oil is routed directly to the main bearings in a Bow Tie block to ensure proper lubrication at high rpm. The main bearing saddles are grooved to increase the flow of oil to the crankshaft journals through additional feed holes drilled in the upper bearing inserts. Block weight is 59 lbs.

Technical Notes: Aluminum Bow Tie V6/60º engine blocks have rough-bored 89mm (3.504") cylinders which can be safely overbored to 91mm (3.582"). Light alloy Bow Tie blocks have bosses for both front-wheel-drive and rear-wheel-drive engine mounts. The starter motor can be installed on either side of the block. The cylinder walls are non-siamesed, and the cylinder deck height is 8.820". Cylinder bore range is 3.525-3.582"; crankshaft journal diameter is 2.65"; all sump type is wet. This block has a 2-piece crankshaft seal and a design maximum stroke of 3.20". It is bossed for front or rear drive engine mounts. Intended for professional competition.


Last time I priced it, it was $3k. again, how sick do you want want?

Tkae that w/the link I have on internal upgrades (pics available upon request until TGO gets back on line)

Ok, our upper and lower intake is aluminum, just not our heads... The aluminum head swap is cool, but you have to change the pistons. Only thing holding me back from doing it RIGHT now. lol Search for it on this board. ;)
