I thought i would throw this out there just for opinions. I have a 95-3500 dually that has outlived its 6.5 diesel engine. I dont really want to junk the truck as I have already put new rear and frontends under it and the body and interior are in decent shape. And I dont want to install another 6.5. Might try a cummins tho if I can find a cheap one. I thought that since my new F450 was getting such poor fuel mielage, I would throw a small block in the 3500 for towing my smaller trailers around. My thoughts are to just rebuild a 350 I have setting in the shop but then got to thinking how to make it a better puller. One thing leads to another, you know how it is. Anyway, if you where going to build a 350 engine for a tow vehicle, what performace parts would you consider. My thoughts are maybe a strokerr crank and 6in rods using heavy pistons, and lower compression ratio (8.5-9:1) for cheap pump gas. That should deliver better lowend torque and I aint interested in high rpms. Then top the engine off with the vortec heads and maybe a rail injection system and hei distributor. Which heads would you look for and remember I aint racing. I also am considering a turbo with low boost. I definately will be loseing the computer off the diesel and would like to keep the installation computer friendly. I have also considere the bigblock, but I dont have one lieing around and those I have found are pretty expensive, late model and will require a bunch of additional electronics I dont want to fool with. Either engine should bolt up to my current flywheel and bellhousing after haveing the flywheel balanced of course. Motor mounts aint a problem, junk yard is full of them. \ Anyway, lets see what you lawn guys can come up with.
