Going along with the previous comment, when you have killer heads and big cubes for a stock block, the best advise I can offer is to slightly under-cam the combo, you'll still have massively satisfying torque and power but by limiting the peak torque RPM you'll resist the temptation to over-rev it and beat the block to death.
Opinions vary, but that's the way I'd do it.
That's the plan!!!
No reason to build/cam it to go beyond 7000rpms Not going to need it not going to use it.

I'm still debating the 4.125 vs 4.25 stroke for my next motor. I have a 4.04" by 4.17" stroker SB Windsor Ford in my Cobra replica, it's got some well ported Trick flow heads and driving it it feels Exactly like a 427 FE big block without all the extra weight, this motor redlines at 6200 which is plenty for a 2450 pound Toy. Good heads with strong mid lift flows are really the key to get the broad torque, too big of a head ( high lift flows) are IMO Not the way you want to go, some of the more race oriented heads don't really flow much if any better than smaller ( less expensive) heads below around .450-.500 lift....so just keep it in mind that big heads really need bigger (less streetable) cams to work the ports....and with a relatively mild cr you may spend much more on the top end of the motor than you need to vs a more thought out solid street combo.  Take a look at Bryce's airwolf torque curve on that 408 with a mild street roller, you could run 3.91 gears at 4000 pounds and still have more wall to wall torque than most street cars can possibly hook, broad torque like that is indicative of awesome part-throttle and roll-on power, that's what makes stroker small block motors feel like big blocks on the street, and what makes the right combo so much fun the drive.

I'm sure you're well aware of a stock blocks limitations. I'm not sure building a 435" engine with a stock block and -1 heads is the best idea ever.
Don't beat on it like a redheaded step child and it should last a while!!
As I stated in my first post this won't be a Race/Drag car!! Just a cruiser with some UMMPH!!
Plus I have an extra already on the floor of the garage and can pick them up all day long for $600 or less.
And a couple replacements with machining and replacing all the broken parts will probably cost what an R3 block does. Do it right the first time.

Might just be a cruiser but we still need to know how much horsepower you want to make. Cruiser with some oomph? If that means 500hp and 550 ft lbs, just bolt on some stock eddies. With 435 cubes it would be there pretty easily.

 - my 430 with a small roller, eddy air gap and STOCK eddy heads made 511 hp
430 with same cam, only a victor 340, and SSDS stage 4's made 566 hp
bigger cam, super victor and MCH CNC eddy's made 627 hp

Sorry to thread jack but Brian, what lifters are you using and is that a stock 59* block?

Yes a stock 59* block with -1 heads. I'm running the 360-1 245 cnc heads on my magnum block with T&D 1.7 shaft rockers and comp offset lifters. I had to grind the block to fit them, well I didn't grind enough apparently and broke two link bars from wedging into the block.

Must not have been 8043's? 8043 lifters are not offset, and you cannot run offset lifters in a 59° block!

Why not???

because those lifters actualy clear everything without grinding,atleast my set cleared everywhing nicely and you dont want ofset lifters in a 59degree block since the ofset cup will try to rotate the lifter and therefore putting a force on the linkbar wich the linkbar is not designed to handle,this is not a problem with a 48degre block since the pushrods dont get as much leverage on the lifter as they get on the "angled down" 59 degre lofterbores. hope that was understandable

Well damn, guess I will be ordering 8043-16 lifters then. Its not a total waste as I plan to get an R3 block soon anyway, thanks for the help.
