looking at 734cc kit with 11.5:1 tech piston, HC3, +3TB, and maby port and polish

How much HP would i gain with this setup, And is there anything wrong with this should i get a different piston or what, i dont have any experience with big bore kits. Thanks

why a hc3 if you go port and polish and stroker and bore??? and gain would be over 12 hp for sure I think cuz a hc3,3tb, 12:1, 5mm stroker is around 10hp I think with stock bore and no pnp

Thats what i said i have no idea when it comes to big bore kits lol. so if i get a big bore theres no point in getting a port and polish?

Our tech piston is not available in the 105.5mm bore at 11.5:1. I did have a 10.75:1 in that bore that was designed for our stroker kits but I wont have any more of these available until early Fall. When we ramp up our winter rebuild kit sales.

no no im saying if your going with big bore and stroker and pnp you should put a nice cam not a baby cam and new springs or else I think your not putting all its potential in use with a hc3

I hear its a great all around cam for mild and wild builds but it depends what you want from your rappy I dont think stroke and bore is needed if you dont drag depends how much you want in performance reability and riding style
