New engine spec to be decided depending on funds, but have started collecting bits and pieces for a Big Block.........Chevy - sorry lads, nothing against Mopar, but this was second choice after the failed attempt with the Rover. Im looking for a streetable 550bhp normally aspirated, all being well we will be looking to add the addition of 100 - 200 extra bhp from a nitrous system, but first we require an engine!
