Ok gang. I had thought my car kicked a rod last week,well after opening it up,i found a broken YT rocker and a slightly bent pushrod,pulled the head today,and looks like there was NO contact with valve and piston.

Now,when the car first started knocking,i assumed the worst and started looking for a new block. I am still slightly torn between forging my current combo,or doing a 370 with an iron block. I just bought a set of trickflow 215 cnc's and really dont wanna sell them and get new heads,hence the stock cube or 370 choices.

I will be getting a procharger F1A for whichever i use,and shooting for 700rwhp (i have an auto,so that isnt a deadset #).bpttom line is i want the car to be solidly in the 10's when its done.

Basically looking for opinions on whether to stick with the 346 or spend the extra cash for the 370. Now that i know i didnt mangle my current block,im thinking to stick with it.

I say stick with it and forge that SOB. The F-1 will get you where you're looking to go. The only thing your losing by not going bigger cubes is Torque.
