We'll see once I yank them out.

1) I looked at your 2 barrel manifold drawing....I think it will pick up additional heat from your turbo manifold
2) and second, the reason why blow through's work better than draw through's is that the carb is in the original factory-designed location for good fuel distribution. The log is not that. Does 10's style 2-barrel is alot better than the 1-barrel, a shorter distance to end cylinders.
3) That's why I favor a tri-power set up with 1:1 linkage.
4) Also, I wouldn't deck the block more than just to make it flat. The deck is thin enough as is. The bores distort quite a bit. If checked with a torque plate you'd be surprised.
5) They say deck height isn't that critical with a turbo engine - something about plenty of squish and faster burn of the denser mixture.
6)I think you'll be in the 11's before you know it. Just let that short stroke, 7 main rev like it was meant to. Have fun!

2) Is there some kind of formula for figuring out what the right proportion of carb cfm to engine size is for blow through?
3) I would think if an engine was responsive and ran well NA with a certain size carb and a turbo was added it would be OK.
4) I wouldn't worry about your rods until you cam it up.
5) Your new cam under boost should have about 300 rpm higher usable rev range than what's advertised NA, if everything else is in order.

you are updating regulary with success and failure. trying unique ideas and doing it all by hand and ingenuity.
GOOD JOB! keep it up.

Compare to this: I got 17.3 @ 122kmh @ dynoed 152hp on the flywheel. You've got some 250+...

Funky Cricket wrote:the great thing is... you have a "fairly" cheap engine that is tough as nails that can hang with a 302 at half the weight. not bad.. not bad at all...
