C5-R block or stock resleeved LS1 block? since the C5-R block has no liners (or sleeves) problems it is save to go with although the price is high, while the stock resleeved LS1 block could have some sleeves problems although some guys had zero sleeves problems with it but it is WAY cheaper than a C5-R block. now the question is which way to go the C5-R block or stock resleeved LS1 block?

Re: C5-R block or stock resleeved LS1 block? Isin't everything a question of Money?? Yeah, cause you already justified that to yourself. When someone comes out and says "What is the next mod I should do?"
The answer is always, "How much do you want to spend."

Re: C5-R block or stock resleeved LS1 block? The C5R block is a sleeved block as well!(95% of aluminum blocks are). We have made 800+rwhp with a factory resleeved block with great reliab. The sleeveing proc. has come a long way from a few years back.
There is nothing wrong with a properly resleeved block and will save you about $4000, in a NA application I wouldn't bother with a c-5r block unless you want the .015" larger bore or are going to put it through some type of prolonged road race conditions?

Re: C5-R block or stock resleeved LS1 block? Nick, why do you think that the only benefits that the C5R block has to offer are for road racing conditions? Do you mean to tell me that there are absolutely no other physical enhancements to the C5R block over a stock re-sleeved block?

Re: C5-R block or stock resleeved LS1 block? Nick, does it mean it is safe to go with a resleeved LS1 block unless i would go roadracing.
and for roadracing the C5-R block is better than the resleeved stock LS1 block.
another question, how do i assure i will get a properly resleeved LS1 block?

Re: C5-R block or stock resleeved LS1 block? The C5R block has many benefits over a resleeve that's for sure! The question is where does the reliab. become an issue and when do you spend the extra money and get value. An everyday street car that has a 422 and makes 450+rwhp will be very reliable with either block, which one to pick? I would error on saving the $4000 and spending it somewhere else on the car, with the C5R you would have a "killer" piece and may not have to worry like some of the guys with the resleeved blocks do.
We have built about 7 or 8 C5r's this year, 2 have been street engines and the others 750+rwhp packages that run 50/50 street and track.
I was not trying to say that the resleeved block is as good as the C5R block, at the high HP levels there is no comparison. The question was made of which block to go with and I know Abdullah runs his on the street, this is why I made the rec. on which block dep. on the application.

Re: C5-R block or stock resleeved LS1 block? Like Nick said the C5R block is an all out race casting made by an aftermarket casting company (Schartzman?) that is siamesed just like a regular small block chevy Bowtie race block. The liners are installed in a much beefier block with a lot of aluminum behind the sleeves and a stronger bottom end as well. Since the sleeves are in a siamesed configuration the entire block is also a little stiffer and stronger and the sleeves do not flex as much as stock or resleeved under extreme power and cylinder pressure so they seal up a little better and also make a little more power because of this.
This would be similar to the difference as say between a Bowtie siamesed 400 block and a normal .060 over LT4 block for example. The bigger stroker LT4 block will make more power and TQ than the 350 stocker but is not as reliable as the all out Bowtie 400 block. However if you don't really need a Bowtie NASCAR block for 500 hp street power levels you may be better off spending your money on heads or intake etc. The race block is better but you may not ever see much difference anotherwords. If you absolutely need the reliability you can always choose the C5R, it's just very expensive.

Re: C5-R block or stock resleeved LS1 block? Does a resleaved block come with studs, main & head? How about beefy main caps? This stuff can add up. First thing to determine, besides the superior casting & sleeving, is what other add ons come with the C5-R block?
I think the savings would not be as much as $4000. I see the C5-R block going for $6000. There is no core charge on that, & it comes with main & head studs, and billet main caps.
Can I get my block resleeved, and the above mentioned goodies, for $2000? I didn't think so.
If I ever build my engine, I would love to have the C5-R block as the base.

Re: C5-R block or stock resleeved LS1 block? I would feel very comfortable with about 600-650rwhp(maybe even close to 700 depending on the combo) and driving it every day as well as running the car hard at the track with the resleeved block. Like I said we have made much more but will not warrantee them up in the very high HP range(I don't think you can find a warrantee @ 700+rwhp even with the C5R block?).
You should never have a leakage problem with the C5R block as there is no water btween the cyl. to get in between the sleeves and cause an issue, this also gives much strength when it comes to cylinderwall distortion @ high pressures( high HP!!)
resleeved block with ARP studs $2350
head studs (ARP) $ 250
total $2600
core $ 500
total $3100
C5R block $6100, savings $3000. No need for main cap conversion on the resleeve, the factory cpas are not the weak link in the block at this power level. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: C5-R block or stock resleeved LS1 block? I thought we all have big budget's PSJ!!! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
I think that the C5R block would be the way to go in some cases if you had a big budget.
