Default Upgrade

Do a search on cams e.t.c. There is a ton of info on OSO on upgrading the 502/500Hp motors. I have a HP 500 I am presently building & installing this week. I went with the139731 Crane cam(most like the 139741), bored out 509cu, cleaned up the heads a little & had 3 angle valve job done aswell. Merlin single plane intake, 800Holley with CMI headers.I will hopefully have her running by next weekend. I believe a blower is the best bang for your buck.
Later John

Really need to decide how much HP you are looking to make. From there you can make realistic decisions on the Parts required and how much $$$$ it is going to take to get you there.
