In the future, I plan on doing a big fuel system but at that time will do rods, gaskets, and head studs. I dont want to tear too much into the motor. I have spoken to people who have done the 3.8 big builds and most of them felt it was not worth it.

 

off boost power is always worth it. its a simple swap liners, pistons and rings. cost is less than 3000$ i like the idea of approx 40 more hp off boost to get the car moving. add some big cams for another 40 odd hp and you have something that will move quick off the line and spool like a monster in boost. the fuel system is the key. we are using a brushless system that can handle 1000 hp on a single pump in the tank were its safe. if the pump was to fail it runs out of fuel and stalls. no worries about running the motor lean because one pump fails slowly and the motor gets hurt. with the custom controller box these systems can even be run a factory dme

adding rods takes the motor down to the case. its only slightly more time consuming to split the case and inspect the crank and replace all the seals and new rod bearings. i never understood dumping all the money for a rod swap but leave 10 yr old rod bearings in. for about 500$ more you have the peace of mind that its all fresh on a big build. i found a #4 rod bearing that hadn't yet seized but had gotten the crank journal very warm. a quick polish cleaned it up very nicely. without cracking the case we never would have known and that bearing was on its last legs
