You can plan on spending close to a thousand dollars to have something like that gone through and made right for a performance application. If you can do the assembly you can save some money but otherwise entry level aluminum heads are worth the cost just for the weight savings alone...

A studded 2 bolt is every bit as strong as a standard 4 bolt.
I'll disagree. It has been my experience that once you go over 600HP range with a studded 2 bolt block you will run into cap walk. If you take one apart and there is gauling on the foot of the cap and/or register then she has been walking. At this point you need to install 4 bolt caps at least on the 3 center mains. I have run into this a few times but had the chance to see it with incremental HP increase in a pull truck class years ago. As the class implemented rule changes and the power grew we watched as the "limtations" showed up.

I will agree with you that it also depends on application. On a motor that will load and unload yes. I have also run 700hp on a studded block with a 300 shot of nitrous and had no issues. I did change the bolts every year mind you and I did also pin the caps. But as far as breaking the block no I havent.

I guess it would also come down to the point that by the time you buy caps, machine the block exc. you are over half way to a dart.

Agreed and finding a shop to properly do the caps is few and far between.

A little ways down the highway from you. Take it east until you see the Atlantic Ocean and then drive North until you are close to Canada. :D

When I said 'I'd buy it in .....' I was saying it as 'If I where you I'd buy it in a second.'
