As long as the 7 bolt block and crank are in good shape, It will get you to those numbers. Rod and Pistons would be a wise upgrade.

6 bolt is much harder to find, and might be more expensive due to it's rarity of only being primarily on the 90-91 models...i'd just build the 7 if i was you

I don't have results, but why wouldn't it be? Especially if its built. Theres proven 2g 7 bolts making more than 450 -500. If crankwalk is your concern, which is over rated anyway then just go 6 bolt.

While a bit beefier, a 7bolt can really hold up well to power increases. Just wisely pick your components to match your power you want to make.

It is the worst common 4g63. 1g head, 2g head bolt size, and then the whole 7 bolt thing.
