Well you cant argue wanting the biggest bore possible as bore is HP. But weight is also a factor, any idea what the weight difference between the two are? Just curious

So in my mind you would need to be able to making enough power to overcome the weight difference to justify the extra weight. Why I have chosen aluminum BB's over the iron brethren. The big difference is the weight difference is larger but the bore potential is the same. BUt that is the logic behind why the Vette has an aluminum SB in it, but we are not limited to a smaller bore because of that choice.

The Ritter block in it's aluminium form is the same casting as the iron version. It's not a specific pattern, I'm not even sure if they've allowed for the different shrinkage rates of the two materials.
I'd want to see some more material in the casting, ribs etc. That's just a personal preference of mine. I think for most of us, the weight saved in an aluminium block is more of a benefit. Those chasing every last piece of HP, in a car they have to add ballast too, you'd go Iron.

A lot of guys go with aluminum for ease of repairing the block when all heck break loose. Lots of junk mega blocks still laying around

It’s too bad the max bore size of the aluminum is 4.120. Does any one know the price ?

Mine is 4.155", I would say 4.185" is about max bore, I think the prototype aluminum block is 4.185". There is a lot of material around the cylinders in this block. I was told that the castings were the same. The weight on mine is 107 lbs. with sleeves and main caps. I need to add for a NA motor.

All good Cab!
You want an aluminum block for track days and road racing. I got an all aluminum Gen3 instead. 600hp at the crank is plenty scary enough when going around a corner!

Just a quick update. After making a few calls and talking to the guys that are way deep into these small blocks, I have decided to take the block to Quarter Mile Performance (QMP) is Southern California. They have all the tools to do what I want plus they have already worked on a few of these blocks in the past so we will get their opinion as well.

These are all good things and I'll share what we find when it is finished being machined.

White Dart is a great source of help and information. I will be starting a thread as soon as ours starts going back together! Hopefully will be posting pictures in a few weeks good luck and if you need any help let us know.


Thanks Jason!

I'll be in touch for sure, lots of little details need to be addressed. up

I'm going to say good choice.. it will require some patience because they are very busy but I assure you it will be worth the wait.. when you get their since you're a paying customer ask for a tour of the shop.. you will be surprised at the names on blocks and boxes of parts that you see.. everything from shops that say they do everything in house to maybe even some top 10 Pro Stock teams. I know you had some other options on block transportation.. but definitely worth a field trip

I think you meant to say hone head and diamonds whistling.. and actually I think that was only for the old head and stones.
They have substantially better stuff than that now.. I think if you have a Target temperature that you can operate the Motor Inn he can hone the block at that temperature..
