It's about time to get the bottom end forged, any recommendations of built short blocks ready to go? I thought the FR aluminator was what I would go with, but noticed ratings on it to only 700HP. Would like a bit more room to grow if you know what I mean.

 

B302, that's what I ended up with, before I started my project I was going with an Aluminator.

 

All I see on there site is the rotating assembly kit. And another question, is a stroked block best for a twin screw supercharged setup, or would an overbore be better?

 

I have only used the B302 from Brenspeed, but it seems to work awesome on my Twinscrew Saleen blower. With the stroker and boost, 90% of your power is in at just over 2kRPM and lasts until 6.

I too was going to go with the Aluminator, but it was back ordered when I went to buy it (about 17 months ago).

Overbore won't really give you much power unless they use a custom block and really give you more cubes. I find the stroker to be great, in that it helps with torque off the line as you build boost. A twin-screw, with its near off-idle torque, plus a stroker, gives you tire shredding fun.
