forged 346

I have a forged 346 with 6.0 liter truck heads unported. I'm running a f1C making 817 rwhp and 690rwtq. So I think you'll be just fine.

thats WAY above what im shooting for so that makes me feel much better, so the 6.125" rod wont require any mods? (I couldnt find the stock rod length)
