displacement

Ok, so I was reading up on connecting rods and the 3.4 has 5.700 inch rods. Could it be possible to put 6.000 inch rods in and shorten the piston height. If possible 0.030 overbore and 6.000 inch rods would make 227 cubic inches and 3.7 litres.

I've heard of it being done on other cars... Longer rods with the same throw does give certain advantages. Quoting from memory, you get better quench, and more efficient use of the combustion stroke. Plus a better mechanical advantage on the crank itself, with better dwell.

Have to be careful of the rods smacking into the bores, and you have to make sure everything gets machined right...

I've heard that small-journal SBC rods can work nicely with a 3.4... Just need to have the faces machined to bring them down to 3.4L rod THICKNESS. the pistons and the bearing bores apparantly will work nicely.

Don't quote me, though... Ask your friendly neighborhood machinist how much it'll be. But SBC rods are filthy cheap. Plus, you can get 3 folks to buy in with you, and you'll all end up spending 1/3 less.
