Then you could run a smaller cam and a dual plane manifold get get it more street friendly and to get the DCR within pump gas parameters. There is no band-aide fix here.
I concur. If your $$$ is the rpobelm get some reconditioned used stuff. Even if you go to a decent iron head...you can get a decent set of reconditioned heads 76cc for about $300-$500...then a used dual plane intake off ebay like someone suggested, and the correct hydraulic flat tappet cam, and a 600-650 cfm carb..then your ready to have some fun on the street. Just doing a cam change or a Torque converter change isnt gonna fix everything. You need new head for sure to bring compression down, a smaller cam and a smaller carb and well as intake.
