trinity 265 big bore kit
- Thread starter 99Blasty

I know they made a 265 kit, not sure about the 295. I think you run into a problem with running out of cylinder wall. You only have so much meat before you break get into the fins. Heat is a problem when thing get thin.
I have heard of a few from a different company but they aren't made anymore. The problem with them when they get that big is you run into cooling problems.
trinity stopped doing the 265s and 295s because they would over heat a lot and they made the cases PAPER thin.
they also didnt make much more power then a nicely ported 240/3mil stroker anyways. actually, most of the 265s had less top end because once the bigger sleeve went in, there wasnt enough room for larger transfers, boyesen ports or triple exhaust ports unless you welded more material on... all of these being gone take away hp and flow. most of the 265s had stock porting configurations... which are ancient (70s technology)
i used to race against a guy who had a 265 and it had a 4 stroke like powerband, very forgiving set up and loved to be bogged but he went through pistons on that thing almost every race.
as the old saying goes, there is no replacement for displacement, but honestly, that goes out the door with 2 strokes, id rather have a quicker reving stock bore/3 mil combo then a 265.

In trinitys 1997 catalog they advertise the 265 dyno at only about 37hp...
The CT 240 dyno is 40hp....I:I
