Great information guys. I would so far, prefer the Blue Thuder heads & intake, with head flow numbers over 400,...... are you kidding me. That's great.
I'm shooting for 625-650 HP/TQ.
No need for really high lift on the cam or spring pressures. I have Ersons on my 428/iron heads, solid flat tappet, with no issues for several years
I'm in contact T & D, Erson, HS and POP, to see what they can do for sponsorship for this build.
Question- What do you like better, bearing rollers or bushed ?
I talked with Doug from POP and his bushed rockers (and shaft) that have a
oil ring to supply
oil.
