Okay, just would like to know what the hell is going on before I even start buying parts for a 383. What balancing options do I have?? I will be buying my own pistons, rods, crank rather than in a kit, so what type of shop do I take it to get balanced??? Would internal balancing be the best then for a 383??

What do the crank hub, balancer, and flywheel all need to be balanced at then??? Would they be neutrally balanced if everything is internally balanced???

Sorry for all of the questions, but balancing is the most confusing thing to me right now before I begin spending gobs of money on a motor.

Thanks

 

Well I did a 383 like you are doing and what a pain in the *** it was. Most cranks are not set up for internal balance. As you know all one piece rear main seal cranks are externally balanced. To internally balance means adding mallory which can get expensive.

When you go internal, the accessories have to be neutral. The balancer is no problem but the flex plate can not be found with neutral balance so you have to pay to balance that too.

The Callies Dragon Slayor crank seems to be the most cost effective crank to get. It seems to need little or no metal added and usually metal removed which is what you want to balance to save money.

Based on the pain I went through, you will be much better off getting a balanced kit. There are very good ones available through a variety of companies.

Long live the 383. Keep marching on buddy. You'll get there.

Good luck

 

Yeah, right now I just have the block I'm waiting to hand out some money for (which I haven't actually confirmed a buy yet)...and an LT4 intake manifold in which I am purchasing in the next few weeks. I'm just in the beginning stages, and this was probably the most confusing part of it all to me.

That info is very helpful and it sounds like the balancing part is just a total PITA from a few experiences that I have heard.

Thanks

 

Doen't the LT4 intake limit your choice of heads? Is there something special about that intake?

Just curious.

 

Yep...gotta have LT4 heads...but thats what I want!! I was looking at the AFR LT4 195cc's with competition street porting and the hydra-rev kit.

The heads are where my money is going to be really spent on this motor.

Thanks
