[formula17]

I've heard this debate a few different times. Most of the comments on it are from people who have no experience with the set up what so ever, but have read other opinions. I have this set up, but it has yet to be finished. All the engine builders I've talked to have no concerns with the set up if done correctly and the correct pistons are used. Power adders are another debate and concern. I don't see the difference between this set up and lets say a 440 set up that uses the same size stroke but with a larger bore. If companies like scoggin dickey, mast motorsports and texas speed sell these set ups everyday I wouldnt be worried about it. As far as one being better then the other I would deff lean towards the Ls7 being better as far as performance, generally its better to run a smaller stroke and larger bore, this is what nascar does. The idea behind this set up is that its more of a budget 427.
