hey guys i now know what route im going with and thats going to be the stroker kit .but im not using the pistons included in the kit using the pistons scamp said i cant sell....but the compression ratio is jumping from 10-1 to an awesome 11.3 -1 ratio.would using 6.1 heads help or hurt ,im gonna be calling the hemi shop on monday but again any info would be great.also with the higher rate of compression would reg pump gas still be good .id be using 93 but a friend said im bordering the race fuel line .im hoping it isnt so .now the hemi shop said that id need to lower the ratio to be able to use the 6.1 because the chamber is smaller or larger cant remember exactly what he said .but im wondering whether the ratio would go up higher with 6.1 heads ,or do i now need to stay with 5.7 heads.

 

Sweet, that's a good route to go.

Isn'tboaring out the cylindars normally part of stroking? If so the pistons will be larger than stock.

 

well since the moor has only 2000 miles its like new .no boring it out isnt manditory just optional.all boring would do is increase size but i will have to hone out the cylinders.i could bore out .30 and get the larger pistons and propably make the motor a 400 somthing cube in engine but im happy enough with a 392 with 600 hp will do the trick on unsuspecting mustangs and camaros .....

 

I may be a bit on the conservative side, but if you have not done this before, you should really let someone do it that has a little more experience. When I say experience, what I mean is someone who has already made the big mistakes, and paid the big costs, in both money and time. What you are proposing is certainly achievable, however there are a number of companies with huge budgets trying to do the same thing with talented teams of engineers that do this for a living, and they are not always successful.

If you have a lot of time, a lot of excess money, then please blaze a trail for others to follow. You may develop what may be the biggest innovation in Mopar technology through serindipity. However there have been more than a few very smart people that after modifying there engines, with the very best parts and technology, have actually lowered the power of their engines. The science of engine modification is something that can rarely be calculated from a sum of the parts, it is the integration that counts.

Since you areat the mercy of the Dodge engine computer, and whatcalculations it makes. Trust me, it does not like change, and can't run without it. Making airflow changes in a hemi engines screws it it up royally. See previous posts on the hemi not having a Mass Airflow Sensor. If you did the same modifications on say a Mustang engine, your probability of success would be higher, because Ford uses a Mass Airflow Sensor. The problem is that Dodge calculates the fuel mixture based on a table of values that is fixed and set at the factory. Whenever you change the engine flow, it looks up the wrong values, and you buy yourself a new engine....

 

I saw Indy Cylinder heads/PPP 426 hemi 300c this weekend ,and the 392 stroker motor was really nice(INDY SWAP MEET) .You ever think about calling them?

 

yes ive looked them too they both seem to be the same .the 426 stroker is for the 6.1 hemi .i was actually thinking about buying a 6.1 block .then i came back down to earth.the are both the same kit and same price so it realy doesnt matter which you buy....
