Which would would fit better for my application? Going with a TRex v2 with a stock bottom end. Later down the road might/probably will be adding high compression pistons, rods, etc.

So should I just go with the 205's and 64cc I'm assuming to help out the stock bottom end or should I step up to 225's... which is meant for larger engine applications, would I lose that much low end torque with these?

 

go with the 205s, you will lose low in tq with the 225s.

 

i would stick with the 205's with a stock cubed motor. i have 205's right now on a 402 because i got them for a good price but when i get the money i am going with trickflows. but if you aren't stuck on afr's you could always get 215's. they would work good on stock cubes or stroked.

 

215's basically the largest for 346ci.? who makes good 215's?

 

215s largest for a 346? Well, many of the LS6 CNC heads are approaching 230cc for what it's worth, and they seemingly all make strong midrange torque. It really baffles me...
