im looking to build a 408 over the summer and im trying to just get all the parts in order. Im going to buy a new lq4 block or a slightly used one. Then im going to get a 408 stroker rotating assymbly from tsp. My question is, what do i have to do to the block to make the rotating assymbly fit right?

 

I'm pretty sure it drops right in, but if you get a used block make sure you can get a good clean bore before you order the kit.

Why not just buy a complete short block? There not that much more expensive?

 

408 is .30 over have to go to machine shop around 200 bucks

 

i would buy the short block but me and my buddy want to make a project out of it and build it ourselves. thanks for the replies guys. What top end should i go with? Im leaning towards a set of stock L92's. Also what size cam? Its going in my 04 RCSB

 

im building a 408 right now and for heads i went with 317 sent them to WCCH sponsor on right, they look amazing

 

Ive head good thing on the 408/L92 combo... That's my future plans as well to have for my DD!

 

I say L92 heads all the way, good bang for the buck.
