switching to 604 from 602

[rubbinsracin]

Ok folks, switching to a 604 for the rest of the year. Can someone tell me what their experience has been going from a 602 to a 604 and the changes they had to make in their setup to get the car to work well?

My guess would be if your 602 setup was good then go for the same scale numbers for the 604. The engines are about 60 lbs different in weight... so just add weight or move weight... don't think the 50 HP is gonna make the setup that much different...

i should have added i have to gain 150 lbs running a 604 as well as the 40 lbs that i lose for the motor. so i will need to find a way to best destribute 190ish lbs. maybe 150ish depending on how much mud i pick up.

hang it all in the middle of the car around 5th and 6th coil and cam shaft height....
