before I asked,serched comp cam's spec.sheet and a rep said thumper was a little much for my set up.He said to try cam # 12-210-2 hyd.flat tappet. My question is , has any one used this cam ? Don't mind a little miles pe gal.spent for that choppy idle. Have 305,headers 650 [4165 carb], dull plane stock spread bore intake, 6 AL dist. stock heads with beehive srings and roller tip rockers.Also stock bore,pistons,and going to run a 200R4 trans if I can find one for the right price for the overdrive. Thanks.
