Does anyone search these days???
The ring lands blow apart from heat/detonation and in almost all cases, it is cyl #5 that goes (first).
If you're trying to reach 300whp, take into account a good running, lower mileage SVX with m/t dynos out around 175hp. So you're essentially needing/wanting to nearly double the hp numbers. That means you need to double the air the engine gets. So basically, you're needing upwards of 15psi to achieve this. 1 atm=14.7psi aka, no boost-n/a engine. So doubling it would get you 350whp. However, then you have to account for losses due to the higher intake temperatures. Get the idea??? Again, this is VERY BASIC and in no way truly accurate, however, it's the absolute easiest and quickest way to estimate hp if you're keeping everything else the same and adding a turbo and appropriate mods.
With that said, at 15 psi, even intercooled on pump gas, you'll be blowing pistons apart. E85 and you should be okay as long as you're not doing endurance racing/offroad racing. But again, it's absolutely pointless to do rods on this engine. If you're going to upgrade anything internal, it needs to be the pistons first. Anything else, is simply a waste.
You're also going with an auto trans, so your stock whp will be even lower than that 175hp thanks to the wonderful losses of the torque converter.
