...and they say magnum heads flow real nice. good enough for a RPM cam, and ProProducts RPM Mag/LA crosswind intake.
a RPM 360 with magnum head will get you so close you couldn't tell the difference.
magnum heads $375 a pair rebuilt. rocker/train stuff you need $180 intake $150 cam $150

$850 rpm package, with heads!!

You would do good if you could get $150 for a bone stock magnum head. A cheap way to make gobs of power would be to have Ryan J or some one put a good port job on them plus a set of the mopar .600 lift springs. They would be cheaper than eddys and make more power. The only advantage would be the weight differance but the extra 50 hp from fully ported mags would easily handle the 50 lbs weight saveings from the untouched eddys. The only down side to going this rout is you will be at the limit with the mags but the eddys could get ported more down the road. Magnum heads are the shiznaz for budjet hp! If you only want 425hp then you can almost do it with no porting at all on them

If you mean Quick77R/T's motor...yeah that's very close to what I'd call a Stage III level iron head street motor.
As Mark says machineing and block prep are key... and not just in getting the motor to 1 -1.2hp/cube, but to getting it to stay together.
One thing I mention in the manual is that the SB mopar has a better port cross section-to-cylinder volume ratio compared to our 440 big block....alos another nice feature is that the cam tunnel is raised in the block which minimizes crank/cam windage, allows more rod room for strokers and aluminum rods and an added benefit is it makes the pushrods proportionally shorter/stronger and lighter which makes for nice higher RPM (but not too high because the geometry could be better, lol) potential.
I'd go as far as to say that if you are looking to go say as quick as mid high 11's with a factory iron head, It's easier and cheaper to do with an A engine A body than it is with a B/RB engine, B/E body and in the case of the still plentiful 360, it makes for a torquey, very streetable combo.

But in the article they used a fresh crate motor and added eddies to get to the 448HP. What would I need to do if I buy the Ram truck motor with 109,000 miles to get close to those numbers without buying the eddies? Would I want to bore the block if the motor is in good running condition? I want a strong motor but one that will be here a long time as a serious street demon. I want to buy you manual, how do I do it? Thanks
