X heads on a 340 HP potential???

swinger, what pistons are you using? because to my knowledge (which is admittedly limited) TRW is the only one that makes a true 1.84 compression height piston to actually get over 10:1 in a 340. the rest are 1.80 and yield closer to 9.4:1 comp

I'm using mahle pistons and have 10:5.1 compression , a similar build to Swinger and am getting 412 HP 398 torque with lunati # 60403 cam
