changing 440 out for 499 low deck issues? - 12/16/12 05:21 AM
will my headers,fuel pump and motor mounts fit the 400 block from my 440?

starter?
thanks
Quote:Just my I think the best practical limit for a B is an offset ground 440 crank/RB rods for 470 cubes for several reasons: rod/stroke ratio & pin height & if more cubes are wanted/needed, to use an RB block with the 3/4" addit'l deck height to work with
I am building a B block stroker,
Quote:I totally agree & on the 30 cubes me & a friend are soon going to start on a 535 cube RB (4.5" stroke) with a 440 source kit/super stealth heads . I told him lets go as big as we can as nobody that I have ever spoken with (or heard about) has built an engine & lamented later on after the fact that they just had too much power to deal with & didn't know what to do with it
The pistons in those 500" kits are like an inch tall. I can't imagine that has any benefit aside from bob weight. there's almost nothing to prevent piston slap, it's a weaker piston, there's higher side-loading.
Since my application is a street engine, w/ pump gas, I want to build for longevity. Hard to give up 30 cubes though.
Quote:My first 400 block pump gas low deck street stroker has 6.800 long rods with a 4.25 stroke (511 C.I.), pistons are very light, 458 grams with no pins or rings but with the oil ring spacer The pistons come out of the bottom of the cylinders a lttle but it has not shown any conscequences form that I ended up swapping the 4.25 stroke crank to a 4.300 stroke(518 C.I. now ) to move the pistons up to zero deck after swapping the iron heads to a set of Eddy RPM aluminum heads C.I. is your freind if your wanting to make power Lots of different ways to make power I've made the same power with different heads using a 470 C.I.(3.910 stroke) as the bigger pump gas motor with similar M.W. ported heads, the smaller motor had more compression and a tunnel ram with two 750 CFM carbs, race gas instead of using a single plane and a single 1050 Dominator on pump gas on the larger 518 C.I. motor
470 is what I have been leaning towards, for those exact reasons. The pistons in those 500" kits are like an inch tall. I can't imagine that has any benefit aside from bob weight. there's almost nothing to prevent piston slap, it's a weaker piston, there's higher side-loading.
Since my application is a street engine, w/ pump gas, I want to build for longevity. In a race application, the issues I mentioned can be probably be planned for. Hard to give up 30 cubes though.

Quote:It depends on what brackets, some the early alternator brackest had two holes in them , non air conditioning cars at least, so you could use it on both the low decks and high decks Some of the BB water pump housings have the bolt boss located in different locations so the alternatot bracket needs to match the water pump You can make the trianagle alternator bracket out of some flat steel or aluminum
none of the brackets will fit?
