[QUOTE="Ex-'93 Cobra, post: 1466381, member: 11332"] Thanks for the response, but, what data are you coming to these conclusions from? No offense to you at all intended ... It is very rare that anyone ever relays accurate data on a motor build unless they have done the work themselves or known somebody who has. I can think of several motors where people sad ... "you could never stroke that" ... or "you could never bore that or maybe you cuold get a mm or two" ... but then next thing you know there are +3-5mm bores and +5+mm stroke find to be very fesable and a great ebenefit in performance that helps the motor to raise over a "plateau" of performance that it wouldn't have been able to achieve otherwise. Therefore, I am very skeptical to comments such are yours. I am not interested in the 2.5 at all, but thanks for the info. There has really NEVER ben a 3.5 to date? I THOUGHT that what I glanced at was a statement of an existing model. Maybe I am mistaken. I know of some places and have some friends that cold help such machining to be very cheap, so I may not care at all. I know one guy who just had a custom made crank setup for a +10mm (101mm)stroke on a factory stroked motor of 91mm from the original motor stroke of 85mm. This is +16mm stroke overall. The block needs to be slightly machined for a very small clearance issue. Nobody thought about stroking the 85mm crank when it was released. The same guy is aiming for an 86mm bore out of a block that people have always said would never withstand anything over an 84.5mm bore. Somebody has already put an 85.3mm bore on the same block. Both motors are inline 6. One will be pushing for CR of 9.2-9.5 for a turbo configuration and the other a 14.5:1 for NA. I understand this may just be a motor that has a lot material to work with, but what you seem to be saying si that there is almost no room or use of a stroke or bore on the v6 DT and I am just having a hard time believing that. Thanks for the input though. Please, keep it coming at will. Back up input with fact data as much as possible please. Thanks! [/QUOTE]
