Been 6.02 so far at 3000lbs...with my little 400/512....It just seems like it does not pull as hard down track as my previous 440/512.....Which got me thinking about the bigger strokers they offer...The 526 and then the 543....Seems like my current combo with 20 more Hp would make it...
I just don't know about a 4.5 stroke in a stock block...
Are you implying that the RB platform makes more power than a B platform in the same type of build?
1.6 intake rockers, have someone who knows what they're doing revise the Indy CNC ports/valve job, and porting the intake manifold would have got you there.
As far as longevity, I agree with HardcoreB's recommendation.
