That should work great , it is an excellent engine combo , very repeatable , we can tailor the cam to your gearing / needs

I went to MRL's website, there was not alot of info however. Muscle motors on the other hand had tons of info. I think I may order from them.
the great thing about mike at mrl is he  WILL GUIDE YOU through your build and share information and back his work and product 100% .

I called MRL and got no answer. I did leave  message however. I got a question guys, whats the difference and benefits of I beam rods and H beam rods? And with te stelth heads out of the box whats the highest compression ratio I can run safely on pumped gas? Thanks guys, I think I am gonna go hughes stroker kits I am just deciding what options I need. Also I need some cam suggestions if anyone has any.

I dealt with Muscle Motors for my stroker kit.
Their prices were good. I went with forged custom made, diamond pistons.

I would recommend you have your local machinist do the final balancing and not let them do it.
I won't go into details but trust me why I know this.

The answer to that depends on the quench built into the system, I think Chryco will tell you 11.0:1 is as high as you should go.  I built my engine to ~10.4:1.

Consider buying the heads bare and having them built with quality hardware.  I bought built heads and ended up replacing just about every part in them since many of the stock pieces are prone to failure (namely valve locks).

I already have my stealth heads. Theyre not bare either, the main things that will affect my motor that are still up in the air are the specifics of the stroker kit, my cam, and fuel delivery system. I still will need alot of help with those things.

for a pump gas engine you want to be below 11:1 but with quench so you want to piston to be .040-.080 from the head with a stroker you will need a dish piston to do this , it has to have the flat top on the quench side but a relief under the combustion chamber to lower compression or you will be over 11:1
 the cam is the most important part of the build , you want the rpm powerband to match intake , head flow , converter & gearing so everything is working together , for example you do not want to be below the powerband driving down the highway @ 70 MPH or the engine will not run efficiently sdo if you are using an OD trans the rpm range has to be lower , smae witht eh converter , if you run a high stall speed but run at lower rpm on the highway the converter will not lock & you lose milage & make extra heat .
 You also need to figure out what cam you want to use , hyd has limitation for ramp sped & spring pressure as the lifter will collapse , the solid seem to work best but require adjustment , rollers double the cost & require special parts to use .

Neil I think you have a good understanding of what I want  can you give me some cam and intake suggestions? If so and you have part numbers that will really help out alot.

Why don't you just have Neil build a motor for you? That way it's done right.
If I cant fix it, it's broke

I would like neil to build my motor but how much am I gonna spend in shipping it to panama? I don't think I could really afford that right now. I had to save to get the stroker kit. How dOes that work? I know Neil has built tons of motors for member but I think freight costs might put that out of my reach for now. Let me know what all I need to look into for a chryco build. Thanks again guys.

I've thought about this as well. Easier thing to do, and cheaper, is to fly Neil to you.
