355 Connecting Rod question
355 Connecting Rod question Alright guys I am starting to put together a parts list for my 355 build. I have the pistons I am using. Pretty much following this guys method.

The engine is going to be a weekend driver/autox/track day engine. Maybe with a few drag nights in there as well. Going all forged to make sure it can take a beating. Wanting to rev to 6400rpm. Aiming for 11:1 Compression on about a cc503 cam with stock heads.
Anyways I am stuck with two questions.
First question. Rod length. There is a 5.7 and a 6.0 inch rod option. I was thinking of going with a 6 inch rod. But what would you guys go with.
Also I have the option for I beam and H beam. I think the I beam will be more than enough for a non forced induction, non nos car. H beam just looks to be overkill along with the fact of the price increase. Going 7/16 inch bolts to be nice and strong.
So let me know what I should go with.

For such a mild build I would save some money and use stock reconditioned 5.7 rods with 7/16" bolts. They can take a serious beating.
If you still insist on changing the rods, I'd use a 5.7" rod in a stock-stroke application.

If you have the pistons, then you have no choice between the 6" or the 5.7" rod. The part # on the piston will dictate what rod to use. Regardless I'd go with the 6" setup for the weight savings and the floating pin.
The stock rod positively can take a 7/16 arp rod bolt? I'm considering this path for my build. I was actually thinking about the 3/8 ones not realizing the 7/16 might could be used. I don't mean to hijack, just adding to the thread knowledge.
