Yes you start with LS1 or LS6 block and have it converted to a wet sleeve setup to achieve a 427. I will forward you some pricing if you are interested

With a new job coming up i will have an extra 1500 a month to blow on the TA. Where do i get a block at first? Need to do it in steps because real bad at saving money. Figured id buy a block first then a package for the internals (stroker kit). Was going to go with a 383, but figured the 427 will not be that much more money or wil it?

It will be about $2200 or so more.. for the sleeves and machining and installation of them.

The 427 will be about $2500 more than the stroker the only difference will be the block and some extra porting on the heads. We are seting up a couple of 427 Darton sleeve blocks at the moment. Let me know we can get you some pricing.

So, comparing a stock block/crank (forged) motor to a stroker to a stroked/bored setup (like the 427), the price breakdown goes like this, correct??

Stock block/crank- forged rods, forged pistons, balancing

Stroker- stroker crank, forged rods, forged pistons (I assume that the cost would be roughly the same as forged pistons in the stock block/crank motor), balancing

Stroked/poked- sleeved block, stroker crank, forged rods, forged pistons (again, I assume that the cost would be roughly the same (within a couple of hundred dollars) as the pistons for either of the other two applications), balancing.

Or am I missing something?? Let's say that you could find a stroker crank for $1k, and a sleeved block for $2500... since we're assuming that rod/piston cost for each motor is the same (also assuming that balancing costs are in the same ballpark), does that mean that a 427 (short block) could be assembled for ~$3500 more than a forged 346??

Obviously, heads to match the 427 are going to cost a bit more, but other than that... or is there a whole mess of other machine work that has to go into the 427??

You better make sure your #8 piston clears the reluctor wheel or you will have one big mess on your hands, KINDA LIKE ME.

you'd also be sure whoever assembles it knows how to check bearing tolerances and ring fit.....

IMO and based on experience, who ever you select to build your engine, have them do the install and tune (turnkey). Eliminate finger pointing. Also go with a shop that has been in business for several years...do not do dry sleeves, consider the C5-R block.
