getting my block done or just buying a 331 short block

[Steeevooo]

what do you guys think? I've been doing some research and I feel it will cost more to get all the work and buy all the parts for my block as compared to just buying a good short block set up...stuck between a rock and a hard spot on this one....just need a push in one way or the other before I drop a few dollars

Is this for your Ford build? if so I know a good engine builder that would build you a killer 347ci engine

It will at least partially depend on what the block needs. I was recently looking into this as well, and a brand new LS2 block was cheaper than getting an old block I have machined, but mostly because it needed line hones on the cam and crank, at least an .015 deck and a torque plate bore and hone from .030 to at least .050, and with the much bore if the block was a tiny bit worse than expected, it would need sleeves, which would have jacked the price up even more.

Moral of the story, do some checking on your block first to see which might be cheaper.

Yes this is for my ford build. My block is a 5.0 out of an 1993 ford bronco with a bit over 100k on it. I'm sure the block would need quite a bit of machining plus from what i have been researching those blocks only handle about 550hp at the crank before it splits right down the middle....so a main girdle would be needed which is another tacked on 300$...all in all the already built 331 short block is looking to be the cheaper route but I am still open to suggestions before I do it

It's hard to give advice not knowing what your budget is for a short block only, assuming a mid range budget ($3000-3500) I think that you could get a great short, the reason I keep bringing up the 347 is because it is the new standard for Fords just as 383s are the GM standard.

I was always skeptical about the 347 kits just because of the reliability issue...i haven't done much research on them in awhile....and yea pretty much my range is anywhere from 2000 - 3000 depending on what I find

We use our 347 to R&D carb and manifold combinations, it has over 500 pulls on it with no problems so if done right it will be a reliable combo the same as any other brand would be with the right parts and assembly.

I will be going fuel injected but I dont think it would make to big of a difference

If you are trying to save some money and you know how to build the engine then go for it.
A local shop ran my buddy through the ringer for $10K 300HP+/- 306 without a dyno tune, and a bunch of issues. This is rare, but it happens.
If you're going to buy an engine get a crate from a reputable builder, or from Ford.
347's were iffy when they first came out with the oil ring/wrist pin overlap. I believe the bugs have been worked out but I agree, I'd rather have peace-o-mind with my build, I'd go 331 with a 302 based stroker.
If you go crate look into 351w based strokers, 393, 408, 427.

Im gearing towards a 331 short block from cnc motorsports and am looking into the 347's

I'm sure you'll do well with whatever you pick, good luck
