i have decided to upgrade from a 305 to a 350, but i need to know what parts i can swap over from the 305 to the 350?

Everything But The Block and Pistons.... You Can Use The Rods, Crank Heads, Intake Flywheel, Balancer, And Really Just About Everything Thats You Wish Too

_________________

thats good to here since i bought a lot of new parts for the 305. isn't the 359 internally balanced? i know my 305 has an external harmonic balancer.

400 Is The Only SBC That Is Externally Balanced. 305 Normally Have The Big Balancer. But ARE Still Internally Balanced.

But Yes The Only Difference Between A 305 n 350 Is The Bore and Block
( Because Of The Bore )

_________________

If the 305 has a one piece rear main seal, it can only work with gen II blocks. Is this correct?
From my understanding, generation I motors can be mixed matched parts to a great degree with concideration to journal sizes of the crank. 400 small block parts can go into other displacement blocks but you need to either run the 400 flexplate/flywheel and H balancer or balance the crank and rods to use the standard Chevy flexplate/flywheel and balancer.

Visit http://www.mortec.com to get some really detailed info on the parts you have or want to use.

Gen I Can Swap W/ Gen I, And Gen II Can Swap With Gen II. They Both Are Based Off The Same Stroke, Rods, And Mains

Yeah But When You Cut Down A 400 Crank To Go Into A 350 Block You Must Still Either Use The 400 Flexplate and Balancer, or, As Already Stated, Balance It With The 350/305 Flywheel and Balancer ( I Have Personally Never Done It That Way But Have Heard Of It ) You Must Also Notch The Block For The Larger Stroke.

This By The Way Is Called A 383 Chevy Stroker Think Its A 6.3 Lt.

If You Wish To Do This I Must Say It Pays Off. I Have One In My Camaro and Even Though I Only Have 308 In The Rear It Will Move It On Pretty Good. I Can Imagen How Well It Would Do In A LUV.

It's a good idea to have the rotating assembly balanced when you assemble an engine, especially when mixing and matching parts. Before everyone chimes in, I know you can get away with it, but it's still cheap insurance. My local machine shop charged $138 on my last rotating assembly. I had to take my crank, rods, pistons, rings, main bearings, 2 sets of rod bearings, flywheel, harmonic balancer. balancer retaining bolt, and flywheel mounting bolts. If you have a standard tranny, you also take the pressure plate. You can also get an adapter to put a gen I crank in a gen II block. The last few bowtie blocks I've seen came from GM that way if you wanted a two piece block. Lastly, your later gen II blocks didn't have a place for a mechanical fuel pump. That's something to keep in mind if you want to run a carb and don't want to use an electric pump.
