Ive been peicing together parts for the new build. I bought a 6.1 empty block out of a junk yard for 150$ and had it sent to the builder to be prepped and made ready. Using full billet forged everything. The short block is gonna be for cost of whatever the products are, seeing as a friend is the owner of the company. I believe we are using h beam rods, scat crank and manley pistons,rings,rods. Im kinda just the guinee pig here with this build. We are sticking with the 5.7 heads and making them a stage 4 with titanium retainers and guides, big block chevy springs and i believe he said something about 2100 ports. Im kinda still new to stuff that in depth. The biggest cam that can be put in a stock bottom end 5.7 is a 219/223 or close and thats whats in mine now. The new one for the 426 will be a 246/251 on a 108 lsa instead of 112-115 like theyre all on now. Also i csnt shift about 6700 so that kinda kills things a little. No one makes any rocker arms or anything like that yet for us or release any pcm/tcm in depth tuning yet. One company has ex chrystler techs working for them and have a tcm to allow 7,000 rpm shifts but they want about 1200$ for that. Ill stay at 6700 rpm. Gonna use a ported and polished 6.1 manifold and a 100mm TB.
The new srt’s for 2011 are going to be a 6.4 392 with over 500 HP NA factory.
not bein a dick butttt if your only spoolin 6700 rpm,s any cam that loose is gonna hurt ya in all areas . sounds like you got a severe overkill goin on and not much knowledge buildin it
