Regarding cams, after lunching two hydralic flat tappets over the past year, GO ROLLER! Pat cited some Erson roller tappet cams that merit some consideration. I replaced the cam in the 468 with a Comp Cam Thumpr middle cam for a Gen IV. I know you can do better with a Lunatti or Erson grind.
Right now I am looking for a 502 short block Gen VI with a build similar to what your looking to get out of your project. See what Pat recommends.
Good to see you're back and up and at em', Pat.......!
Thanks for your reply, I am listening to Pat when he says stay away from Comp. I don't want the thumpr because they promote it solely for the sound, which goes against everything in my book. I'm thinking about Howards because they have cam and lifter combo's for around 500 bucks! Someone also told me to go solid, so thats crossing my mind as well. I have never had a solid cam so I'm unfamiliar with them, but I hear they are better for power and stability than Hydraulic cams. I know I would have to adjust more often. I still have to buy pistons, complete valvetrain so options are all over the place, can't decide.
