i havent bought none of this yet just want to get some input what would be the best combo ,im wanting to be able to cruise but to be able to get get some neck breaking hp as will
if anyone has any changes in items listed  that would be better ,also the cam selection is partilly based on it being a 3 bolt cam that i could use with winning timing gears

To me its a no brainer Combo #2 for the simple fact that you will REALLY feel the extra point of compression and still be able to run pump gas (93 octane) fuel and have yourself a 500+HP/TQ Street ground pounder.   The car will make more power, sound more aggressive, and be more responsive and still be reliable if properly built.  

Because the following cam was highly recommended to me by the Cam resident guru here, Ron (Firefighter) and at least one other reputable engine builder here, for my 440 hi perf. build for this winter running 10:4 to compression, and proven to make in excess of 525HP and Torque with out of the box Eddy Heads, I recommend the following flat tappet hyd. Engle 3 BOLT cam that I bought for my build based upon the aforementioned recommendations:

K58 is 230*@.050 & .514 lift
K60 is 238*@.050 & .534 lift

If you upgrade to this cam call Chris at Engle, google Engle Cam for their number. GREAT customer service from Chris and very friendly ad knowledgeable to.


OH yeah, I forget to mention that if you go with combo #2 then I would get the 84cc Eddy Heads, b/c you will get the same compression 10:3 to 10:4 with the thinner Fel-Pro gasket with a Flat top forged piston installed in at 0 deck height.

Best of luck to you with your new build

I would pick combo #1 with the 84cc eddie head.

I would pick combo #1 with the 84cc eddie head.

  And zero deck the block.  That"ll give you about 10:1.

[73chargers4404]

stupid  question how does one zero deck the block

[BSB67]

stupid  question how does one zero deck the block

It is the machining of the block deck surface so that when the pistons are at top dead center, the piston top is even with the block deck.  Without doing this, I think those pistons will be about 0.020" in the hole.  With the zero deck, you would then use the 0.040" thick Felpro gasket that is commonly used.  There are other combinations of gasket thickness and deck height to get the same result.  Ideally you should try to get a piston to head (closed chamber 84 cc head) clearance of 0.040".

Will at least going with Eddy 84 cc Heads is a unanimous decision here!

had a set of those speed pro pistons 9.9 comperssion didnt like them they were way to heavy compared to the ross i bought or the 440 source i have now just saying

[FLG]

I went with icon IC9953 (forged, icon makes em for keith black)...your not gonna find the speed pro pistons any more, theve been backordered for a looong time.

[73charger440]

the rebuild kit  has a ship date of tomarrow when u look at it online

[73charger440]

are these the ones ur talking about http://www.summitracing.com/parts/UEM-IC9953-030/ ,     would u know what the compression ratio is on those

[FLG]

Those are them. Though the weight is wrong, there light but not THAT light.

Comp ratio will depend on what your head cc's are, bore, head gasket, and piston to deck height. Just because a piston is advertised at 10:1 or whatever it may be, does not mean it is.
