If you prefer a tame running motor with a smooth idle and excelent idle off idle driving response why not change the cam?
A cam like the Comp Dual energy 265DEH will probabily suite your driving style and purpose
a whole lot better. It will still go like hell.
1.6 rockers gets you high lift and short snappy duration with this cam.
265-269 211-221 110lsa .471" .495" lift when using 1.6 rockers.
This cam matches your lil 670 carb a lot better. strong power to 5500rpm
very resposive at low speeds. good on gas.
Your 9.2:1 compression is lame. You are 1 whole compression ratio shy of what the Comp Magnum 286H-10 cam likes best ...You could supercharge that thing.
You would really like a weiand 144 blower on it.
Cures all throttle response issues instantly. LOL
Start by correcting the distributor advance curve with 24 to 26deg initial base at idle.
huge difference. work form there.
