Hi, I need some advice with cams.
I am looking to up grading to a lumpier cam for the a15.
Can anyone tell me where is the best place to go to for Dato cams in Sydney.I am going to give the the beast a new lease of life. .40 thou oversize pistons, worked head(ported and polished),double valve springs (shimmed),head shave,and hopefully some Weber carbs to finish it of. Also can anyone tell me the diff between a closed chamber & a open chamber head??. Thanks.
