Combating True KNOCK
recemtly had a 382 built for my car. Well the comp ratio is higher than id like and i get a little bit of real knock when in 5th or 6th gear. And knock when at WOT. If i add some heavy duty octane booster (offroad use) the knock will go away same as when running race fuel. So the knock is real.
With my Lunati stroker kit it brought the comp ratio to around 10.6.1 well add some heads milled about .40 and you climb into the iffy pump gas range. 11.5.1 and above.
So what could i do to combat? Thicker head gasket? I dont want to tear her down so soon.
What about a 160 deg thermostat and LS1 edit to change the fans? Right now i have a 178 deg thermo.
The new electric WP might help out.
Right now the car has 22 deg of total timing. It had no knock on the dyno but on the street i have knock.
HELP FELLAS!
