88 Mustang GT

All the minor things needed to pass the NC state inspection have been repaired and my 88 Mustang driveable. Now, I'm ready to work on the engine. I have a little white smoke, and what seems to me like excessive amounts of water coming from the exhaust. I'm also starting to hear a little tapping or rattling. Also, I have a oil leak around the main seal. So I know alot of work needs to be done. The question I have is, I also have a old 351W that I've had sitting around for a while that I think I want to have rebuilt to put in the Mustang. If I'm just planning on having the 351 rebuilt with no upgrades, can I just have it honed and reuse the same internals? I figure a stock 351W will still give me better performance than the 302 I have now. If not, what would be a nice reasonable upgrades for a 351? No racing, just weekend fun.

The 351W will be a good upgrade for that car. As far as internals, you can reuse the pistons if the block don't need bored, rods & crank but you need to have those checked by the machine shop. If the crank needs turned, you can buy oversize bearings. Do not reuse the cam & lifters, buy a new set along with a new oil pump.

You'll need the accesory brackets from the 351, its taller than the 302. But plenty of companies sell parts for this type of swap. Are you keeping the EFI or switching to carb. EFI is a great way to go, but will cost more than a carb set up.

The car was already converted to carb, and I have all the brackets I believe. The one thing im not sure of is the flywheel. The motor was bolted up to an automatic and I will be running a manual. I was told that I would have to change flywheels. Is this correct?

oil pan fit

351 oilpans are different and all the fox chassis 5.0 's use a double sump oil pan. and long pickup tube. Check Ford Performance for a new pan. usually you can get a free DVD of the parts catalog. flywheel balance weight changed on 302 to 5.0 , I don't know about 351, what weight they used.

I knew about the oil pan. I found out the hard way a while back when I was changing out a distributor and the oil pump rod fell in. But I am going to look into the free DVD. Thanks.
