The Eagle assembally is the cheapest forged assemablly out there. The cut in cost has to come from somewhere. IMO, they can't be compared to Callies or Lunati, there's just no way. Not to say it isn't a decent crank for the money. Eagle kits are $1900, wearas the Lunati's are over $4k. People spray stock rotating assemballies all the time, so I don't think you will have a problem spraying the eagle kit. I do believe that the assemablly will have it's limits though, were I don't think the Callies or Lunati will have a reasonablly obtained breaking point. A sleeved block will deffinatlly cost more than your rotating assembally, there's just no way around it when you buy a $1900 rotating assembally. I still have my sleeved block FS and would be willing to make you a deal on it if my auction dosen't recieve any bids. I believe you are the one I spoke with through ebay? The 4.125 bore will unshroud your valves and leave enough room between the edge of the valve and the cylinder wall to disburse the air properly. 440 ci's sure sounds better than 393.

 

I see in your sig you have a Futral cam for your set-up, I would call them about a 402 LS2 definately. You could also try Rapid Motorsports and H.P.E. to talk about the set-up that would be best for you.

 

if you would be happy with numbers like this, then go for it (Keep in mind yours will be lower because its an auto). If you want to get into the 500+ club, then go with a larger bore.

Also you can call LME--->sponsor. Most of the fast cars (8 seconds) use their motors.

 

Will my heads bolt on the 402 i thought the head gaskets were different

 

Yes you would need a larger bore gasket, but that isnt a big deal. The heads bolt right up. For this application I would really think hard about an iron block and with a 4.040 bore. Sounds like you are on a budget, and that option is hard to beat. Yeah it will be alittle more weight, but with the kinda power you will be making it will be unnoticable.

This is incorrect. Cubic Inches = HP.

In the perfect world I'd take the biggest bore possible and the biggest stroke possible, but if he has to stick with an aluminum block, and can't/won't re-sleeve it, this is the best possible combination. There is no replacement for displacement.

And with Patriot heads and a 4.100 stroke you can expect to make a ton of TQ, but not a lot of HP.

 

I think i could wait alittle longer and get a 402 form TSP how much more do you think it would make than my 393

 

ttt....?????????????????

 

probably 30-40 hp more. You could expect 480 or so through an auto with a really nice set of heads. Those patriots aren't going to cut it though for those numbers though.

Well I have seen all of these kits and I would say the Eagle can probably take more NOS than the Lunati stuff since the Lunati Rods have been known to bend with severe NOS and the Eagle and SCAT H-beams have not. I know of three cases of the pro-Billets bending and I haven't seen this with the regular H-Beams so it's not a crankshaft thing but rather a connecting rod thing. ALL the steel cranks are overkill basically. On the pistons we use the Wisecos which have very NOS friendly ring lands as compared to other shelf pistons and there are also some very nice Diamonds as well. The NOS tune is probably more important than all of this though anyday!

I'd say the Callies cranks are a great middle of the road option and still much less than the Lunatis but again we have never had problems with any as far as strength or breaking in the first place.

 

Thanks any more info out there

 

Who cares about HP/TQ numbers....I wanna know some 1/4 miles times here!!
Im also looking at the 383 stroker rotating assembly from Eagle. I have no other choice because money is in short supply. Ill get ported heads, new cam, and either forged rods and pistons for a 347 or the Eagle 383 stroker. The eagle 383 is my pick for some more cubic inches. A lot of guys are not in the boat to be able to spend over $5k on a motor, or at least I know Im sure not!

On a 383 stroker, with a big cam, and some good flowing heads ABOUT what kinda 1/4 miles times are we looking at. Personally Im running a Th400 3800 stall on a transbrake, and Moser 9" with 4.11s so I know Im not gonna get a huge rwhp/rwtq number.

Alot of people on here keep saying "theres no replacement for displacement" then some turn around and say there are more 346/347 cars running quicker and putting out more power than 382/383 strokers. They say with the money you put into a 383 stroker you can put into the 346 and make it just as quick! That doesnt make sense to me, but maybe Im not seeing the whole picture. Can anyone enlighten me on this?

 

On the all-stroke.

If you take a top end that allowed a 346 power to 500rwhp, the 396 all stroke will
power to more but at a lower rpm point. HP peak will be reduced about 500rpm,
but the power will be a bit higher. The power output WILL NOT be proportional to increase in cubic inches. Happens like this all the time with 302 stock bottoms swapped for 347 in ford.


However TQ output WILL proportionately increase. So if you where making 420rwtq,
it will increase by the 15% or so to 470rwtq - as example.

We all know its not the best idea to go all stroke, but if thats the only direction you can
go its better than none or turning a million rpm to hit the goal.

 

thats a good point! If thats all you can do with your budget then its better than nothing!

 

I have a 395 in my car, I went from an all out 346 making 450 rwhp and drivability sucked in this set-up. My 395 is a much better motor due to instant power on demand. The 346 motor had to rev. up to get the power and from a slow roll it sucked till it got over 4k. My all stroke motor will set you back at 1500 rpm.
I have patriot heads but have been redone at Sunset with 2.08 valves and a race port, Texas Speed had them done. I have a much smaller cam then you were thinking on using. Mine is an M-6 though.
489 rwhp and 471 rwtq.

 

it seems when people wnat power and on a budget, which is usually most of the time, they wnat to take corners and the fastest way to attain a given goal. IF you feel that this is wat you want than go ahead....

but imo, i would just hold of and wait until you are conpletely sure. But notonly that, if you can get the crank, for example, than just wai a sec. or two, and get the best crank. It will pay off down the line, though any part will break given the right or better put, if subjected to an imbalance of pwer and reliability.

MY 408ci has lq9 heads, aluminum with 2.08/1.60 valves (ferrea), and flow over 330cfm at 600 lift and higher. However, you would need a balanced manifold to take advantage of this. Also, i elected for a set of callies rods and crank, diamond "coated" pistons with the 6.0L iron block. Trust me, the weight difference isnt a big deal.....

The only problem i have is that that combo isnt balanced and would need a bit more bore to maintain a harmonic balance. CI=hp , yeah so does bore, and higer rpms, increased combustion efficiency. There are many ways to obtain power but you hae to see what fits your style.

Ok, here is a comparison, my 408 through a M6, made 537rwhp N/A. (Its another member but i really cant remember his username...DOH!!!!) However, in thsi thread another (antzta ?) member with a 395 stoke combo made 460rwhp N/A. Our cams (246/248 603/617 114) our similar, heads are suppose to be similar but the 408 made more power. IMO, its a better combo not because i say so and that i have one but its balanced and better equipped to to the job. You would loose to much power in try to balance the pistons on your stroke (and the added friction which is of course lost power) than on ours. Yes, we have similar strokes but since we have a larger bore, we are making more overall power or are better "equipped" to maek more so the frictional is percentage is less than your setup...

make sense..... well, good luck!!!!!!!!!

 

Hey man thanks for the great advice. I decided to get a 402 ls2 and she should be here this week so we will see what happens

 

well being your comparing apples to oranges lets compair our 395 makes some nice power also also we droped the compression with the afr heads to 9.5 to 1 and made 490+ hp ill give you that dyno sheet tuesday when we reopen .

looks like some serious valve float on that lower dyno graph very choppy.
