350 or 383?

I just got my new project home and it has a 350 bored 30 over, newer double
hump heads, a small cam and double roller timing chain and headers. The guy I got it from left me a second intake and a dress up kit. I have the opportunity to trade some of the extra parts for a 400 crank and rods that came out of a 383 stroker. Big question is should I just stay with the 350 or go ahead and put in the parts since its already bored out?

Re: 350 or 383?

Are you ready to do the work on the lower block areas to allow for the clearancing of the crank? If so, then you have much to gain and nothing to lose by making the engine a 383 stroker. Be sure to inspect the rods and crank carefully for any fatigue issues. I blew a big hole in the side of one of my blocks when the #3 rod broke on a stroker engine. The one that I presently have is built with much healthier material and if it fails, it will be my fault without a doubt.

I haven't tore into my motor because it was rebuilt not too long ago. I do know that the crank and rods came out of a motor that just blew. The guy said he didn't break in the cam right and they have about 5 miles on them

If tha motor runs good..run it as is..383's are great, but wouldn't put unknown parts in a stroker..those kits are cheap these days & you might as well start with a matched kit & not pieced together stroker..IMO..

I'm not a motor person by any means so I'll probably just keep it as is because the guy told me all I would have to do was drop them in and no machine work would have to be done to the crank or block.

If you want a stroker, build one at your leisure while you enjoy what you have. Sell the 350 when you are done to recover part of the cost.

A motor build that starts with "the guy said" usually doesn't end well. It takes more skill and equipment to evaluate used parts and build a motor than it does to buy new parts of the proper spec. If you do go the stroker route with your current motor, ask around and find the best speed shop in town. They will be able to give you the truth on what you have and you can build with confidence.

Re: 350 or 383?

Yeah, good point. We don't really have any kind of speed shop I'm aware of and I'm going to be going at this build alone, so I'm just going to do what little I can to the truck and then start saving for the rest a little at a time. I have big plans for the truck but it may be one of those projects that takes several years... Lol
