was just woundering if i can take an automotive block and put all my marine rotating assembley in it if it would still be the same my reason for doing this is that the previous owner never winterized the motors and in result the blocks are cracked

Yes, start searching and reading.

dont forget the heads,exhaust manifolds,and anything that water can freeze in.

And if they are vortech engines make sure you check the bottom of the intakes for cracks as well.

Yes last summer I did this exact thing for the exact same reason. I used an automotive block without an issue. Be sure you use a block of the same vintage as the one removed to allow for reuse of oil pan and accessories, there were several configurations through out the years.

+1 the late 90's alone have three different variations of this engine

If you use the nice plastic Vorted timing cover on an earlier block it will leak like the dickens . Unfortunately, it won't start leaking until after you break the cam in and you are 5 miles into your first outing.....

I never thought locating a sbc would be such a big deal but the whole cash for clunkers really messed that market up hopefully today ill have one the biggest issue was making sure it had a fuel pump provision does anybody know where i can get torgue spec for putting the new motor together as far as mains, rods, and roating assembly dont know if the specs are different from automotive to marine any help or suggestions would be of great help.

I've used Wheeler reconditioned blocks on two seperate occations when machined blocks were needed in a hurry. I received them in less then a week. You will need oversized pistons and rings. They come CNC clearanced for 3.750 stroke, you could build ut as a 383 for not much more money. As with anything, all of the oil galley plugs need to be removed and final washed. I don't know if I'd order a complete engine from them.

I used them in a past when I helped assemble some old 440hps, had everything we wanted to know. Tourqe specs and factory tolerances. Wiring diagrams were nice too, we made our own harness.

For $35 hard to beat
