Default 408 iron block build

Please move this if it is in the wrong section...

I have been planning on buying the heads, cam, intake for a (planned) 408 build and running them on my 346 until I have the money/time to build the motor (most likely next summer). However, I figured the downtime/cost of tuning on the 346 car would not be worth it in the end. I would like to get my hands on a 6.0l block and beginning the 408 build.

A few quick questions.

Would I be fine getting a used 6.0L iron block or should I get a new one?

Would the cost of having the old block machined be less than the cost of a new block ($699 from TSP)?

Who has the best prices on the stroker kit for the 6.0l to bring it to 408?

Sorry for the noob questions. I am just trying to get some costs together before I jump into it. I know it will be costly but this will be a year or so in the making. If there are any links to a site with this build on it send me some links. Thanks for the help fellas

Its fine to use used blocks as long as they are in good condition.

Most new blocks end up getting line honed, bored & honed, and decked just like the used ones, so up to you.

You are going to have to shop around for prices, sometimes there is sales at different places at different times etc., etc.... Look at the supporting vendors.

Good luck

That HPE shortblock looks to be a good deal. Would it be worth it to build the shortblock myself with a 6.0l block and a stroker kit, or is it better to go with the shortblock and just go from there?

Ballistic Jello thanks for the info!

Its WAYYY cheaper to goto SDPC or LME and get a complete shortblock from them . I know building 1 as we speak.

I would go with FFHP or HPE. I personally went with HPE because they do everything in house, they don't outsource any of the work. I like for one shop to be accountable for something rather than multiple ones that can turn into "they did it" wars if the engine takes a crap.
