_________________________________

Thats what i currently have not the best setup but to get alot more out of this i was wanting to go big with the crank but im told that is 1k in case work alone but i dont want to be cheap ...

Can u tell me what i can get out of the right size carbs 4mm crank timing plate and race gas if its worth it....

Or in your general opinion what should i do next with this engine build and what kind of numbers can i expect.

Case work for a 7-10mil will cost 300. Good billet cranks 7-10mil 1100ish.
If your only working with 2k, get a 421cub. Would make 70-100hp depending on who does it.

if you are bottoming out, spend that money having someone set them up properly for your weight and suspension.

Don’t get a cub unless you strictly drag race.

beat bang for the buck is a DriveLine cylinder set up for 800$. You can keep the stock crank and be running 392cc. Have DL add the boost ports and let it rip. Add carbs and your remaining money out into a rear shock

7 mil driveline setup, you dont need a billet crank.  thats your best bang for $. and they are proven setups

you will spend under 2k for their crank, top end, domes and case work. numbers depends on whos dyno its on.  close to around 90 on pump gas with 35mm carbs, dont bother with race fuel unless you dont mind spending an arm and leg for a tank of gas you will burn through in under an hour.
