Roller cam idle RPM

Thanks guys.That shed some light on it.Thanks for the compliment on the engine.The car is pretty ugly right now being its in primer,and i see alot of guys snicker at the local donut cruise lol.But id like it to run like a bat out of hell before i clean it up to much.Ryan chose the cam after doing the heads for me,although i ended up bumping the compression up after the fact.The lifter bores are not bushed,he just had a set of Chet Herbert rollers made to work in the stock bores.The cam was an afterthought.When Ryan started on the heads and found out the rest of the package,he recommended i change a few things.It seems he definately led me in the right direction,and although i spent WAY more then i had anticipated im very happy,and he gave me tons of advice.Im sure he was happy to get rid of me lol.I later saw the crossover oil mod that your talking about.Next time its down i will do that.
