Just needed to know which is better everything else being equal.
427 C5R Vs. 427 Darton ( re- sleeved )
Pro's and Con's for each...I'm trying to make a decision. Thanks

the C5R block has no comparrison to power and reliabilty it can achive.
a Darton sleeved 427 is a great option if you dont have $6 G to spend on the block itself.
Or Katech now makes a 427 out or a Katech cast LS2 block.

C5-R hands down. Why risk a machining/installation error or defect on the sleeves when you can get a block designed to do exactly what you want?
Given the price tag on a C5-R I think I could be happy with twenty-five fewer cubes and get an LS2 stroker. Food for thought.

LS2 with a Darton dry sleeve installed....
4.155 bore potential with plenty of wall thickness and integrity....less chance of a problem when compared to the wetsleeve process and half the cost of a C5R. Strong because the OD of the LS2 blocks are beefy even after having the material removed for the ductile sleeves.
Or as others mentioned save your money and build a killer 402....similar power but less TQ (assuming the same induction) which might be a good thing depending on your set-up.

some tuners won't do a 427 Darton. They have had problems then have to redo the entire job and eat it. If I was doing a 427 I do the C5R block. I'll probably do a 402 in the future when mine pops.

And how much does a nice 427 cost to build? Two grand is not in the picture if I am spending 20,000 I'd go for it. I got prices in the 25-30,000 for a good 427.

You can build a C5-R for far less.
Block - $6,000
Pistons, rods, rings - $2,500
Bearings, bolts - $500
Heads / intake - $3,500
Machining / assembly - $2,000
Unknown doo-dads - $1,000
That's $15,500.

I have also looked at a Darton Sleeved GM LS2 block and a Katech Block LS2 427's.
Dont forget IMHO the most important part, what do you want the engine to do?? How many RPMs do you want to spin? How much TQ and HP are you looking for? Reliabilty issues?
Dont do cheap parts when building an engine, It cost less to spend more when building it right the first time, then to build it cheap two or three times.
