Right now I think i'm in the upper 300's RWHP in my car, I don't have the dyno sheet handy. I am happy now. I just like to know what to do if I had a failure. I have a C5 with a 427 in it....the extra torque is really sweet!

If you are going into the bottom, big bore (4.125) and offset ground crank is best bang for the buck to increase cubes. Still a lot of $$$ though.

More never seems to be enough. If you have 300+ to the rear wheels now, just wait until you drive a cammed, ported car. You'll be hooked!

That does sound like the right way. I am sure that the bigger bore would increase head flow "a lot". How much does the small journal/offset grinding gain you cube wise?

When hooked on the quest for more power at some point to much is still not enough.

I think it was the late great Mickey Thompson who said "Too much horsepower is almost enough" --Bob

I have the single mass flywheel. I had the idle set at 850rpm and the chatter is almost gone. I do have 3" Tri-Flo B&B though. Can't really hear much of anything. hahahahahahahaha Only the roar when I drop the clutch!

Yes, very true bigger bore way better flow. 4.125" bore X 3.75" stroke = 401 ci Pete
