thoughts about 273er combo

hi there Fabo Bros and Sis...

just wanna here your opinions about this combo for my 65 bcuda

- 273 block from 1965 (we will see if i have to overbore, at the moment it still stored in my friends hotrod shop, it´s the original block the car came with as i bought it)
- a pair of 920 casting heads (plans are gasket match the intake runners, bowl blending, little port job on intake and exhaust, polish combustion chamber)
- also planned to use 360 head sized valves on these heads
- long tube headers and 2,5 dual exhaust
- cam will be an ssi 11309 (lob 112, duration 050 lift 204-214, ad dur int.270 exh.280 Valve lift .420 .443)
- valve springs compcams 901-16 (353lbs seat load 101 closed load 242)
- intake LD340
- stock crank and rods (maybe i will polish them)
- pistons not sure about which way to go, as i have a set of low comp standards and also a set of sealed power aftermarket 0,30 laying around
- carb will be a TQ 750 or 850cfm (got 4 carbs laying on my workbench 1x750 3x850, we will see which one will be worth rebuilding)
- trans will be standard 904 (pushbutton) with standard converter (may be i will use a /6 converter)
- gears are 3,23 at the moment but thinking about getting 3,73 or maybe 4,10 (depends on what i can get for the 741 case)
- 26 inch tires

goal is to build a streetable car with nice acceleration (just to make the chebby guys wandering about this tiny engine) using pump gas is also a must as fuel is getting more and more expensive and more worse in quality here in Germany (the worse quality of sheel v-power-fuel has killed my 11,8:1 CR 318 teenie-screamer)
