I hear you. Once I get it on a dyno we will see. I think he can tune it in. As far as the 62mm...its been bought just not received! The dyno shop said he can give it a good performance tune with the 62mm but not push it over the top. Reading all of this forum reminds of the motors I built years ago. "Need a 750 Holly and port/polish those heads!" I built a lot of motors albeit carb motors. Stroked them, 202 head debate as opposed to 194, etc. Always something new. I think with the 62mm, cai, and a dyno tune the AFRs can be managed and a solid mixture ratio established. Once I go nitro (down the line) I will go with the tuner's suggestion. I read all of the list of parts guys are putting on but they are racing. I think for daily driving with just a little kick when I want it I will be fine. Thanks Aero!
