Hey guys im building up my A12 and was wondering if twin 40 dellorto are going to be too big for this build. I have .040" over flat top pistons, stock head with dual valve springs, 4.1 extractors with maybe a 2" exhaust (not sure if going to be too big aswell) and my cam specs are as follows
| Advance Ground on Cam: Lobe separation: 107 |
| .050 VALVE TIMING |
| Inlet opens: 13 BTDC Closes: 47 ABDC .050 Duration: 240 |
| Exhaust Opens: 47 BBDC Closes: 13 ATDC .050 Duration: 240 |
| ADVERTISED VALVE TIMING |
| Inlet opens: 40 BTDC Closes: 74 ABDC ADV Duration: 295 |
| Exhaust Opens: 74 BBDC Closes: 40 ATDC ADV Duration: 295 |
| Inlet lobe lift at TDC on the over lap:.084 |
| ----------------------------------------------------------------------|
| Valve lift Inlet: .4118 Inlet Rocker Ratio: 1.50 |
| Valve lift Exhaust: .4091 Exhaust Rocker Ratio: 1.50 |
| Valve Lash Inlet:.014 Valve Lash Exhaust: .014
Your help would be greatly appreciated because the carbs are the last thing left for me to order before i start rebuilding, so if you have a different carb setup you think would be better or think i should change anything in the build let me know. Im new to the datsun scene and need your help.
Thanks in advance
