Default 427 on a budget?

Whats a cost effective way to get a 427? Is it possible to build one with a C5R block and stay at or under 12-13k?

I don't see why not. The block will run you $6k, the stroker kit can be had for $2-$4k depending on the brand, some good heads will be $2-$3k. You should be able to build one with a eagle stroker kit and AFR 225's for 12k assembaled.

Default cost effective 427

Darton will be coming out very shortly with a 4.125" dry sleeve for the LS2 blocks. This has been long in coming but we have been very busy with other projects.

Pricing will be around $1,500 installed in your block.

Same exact centrifigally cast ductile iron material used in the Top Fuel and MID sleeves. In other words, the sleeves won't crack.

Why the price difference in sleeving the LS1 and LS2 blocks? I was quoted ~$1000 more than that for sleeves installed in my LS1 block. What is the difference? Just curious, thanks, Shawn

Default sleeves

The LS1 uses a wet liner (MID). Runs about $800 more than the dry liner. A lot more involved in making the sleeve and installing it.

The MID in the LS1 block is the strongest thing going for a high effort engine. The dry sleeved LS2 will be plenty strong enough for most applications. They will not be as easy to replace as a wet liner however. That is another major benefit of the MID sleeve.

The current MID sleeves will go to 4.160" bore. Hopefully, blanks will arrive shortly so we can get going on the 4.200" MID sleeves for the LS1 blocks. There is no way to make the dry liner go that large while retaining sufficient wall thickness.

What about an LS7 bare block? Does anyone know if the dimensions are the same and if you can use the internals and heads from an LS1 on these blocks? If they are the same you could get a Lunati or Eagle stroker kit, some Afr heads and Fast 90 intake and put one together on a budget. From what I heard the LS7 uses titanium rods which are the most expensive part of the new engine. If you could get a bare block for 2K and everything bolted up it might be a way to go?

I don't think the ls7 block is compatible with any ls1/6 parts since it has a dry sump oiling system and the dimensions are different than the ls1/6 block. It is a shorter block with taller heads.

You'll need you basic stuff like gaskets, oil, coolant and so on. Most things like pushrods, lifters, intake, and rockers can be used from your existing motor. A FAST 90mm intake and TB would add a good bit of HP, but will cost you another $1200.

once you add in the extras because I don't really believe you want a cheap 427. Its gunna cost more than what your wanting to pay. I'm not saying it can't be done. Just you might get a call like we need these gaskets and these lifters, would you like this intake ported. Your gunna need bigger headers. All those little things that you don't think about.

i think you are going the wrong direction. but thats just me. you feel as if the 346" ls1 is not a strong motor for your needs?

besides, 383LQ4SS (al jones of tampa) just had his short block iron ls1 put together (414 or 415") for under 6K. he is goign to make around 1000 rwhp

Default 4.200"

It is taking a lot longer than it should because Darton is very busy with other products. Should be another month by the looks of things.
