When you say the TH has a multi fit pattern, what is the other pattern! BOP!(buick olds pontiac!), it's a bit of a mission redrilling most 308 blocks to turbo pattern, due to there not being much casting around where the turbo dowels have to be, later blocks are better in this area, you could just get hold of an adapter plate for now, but its not my favoured option

thanks so later block is the better option!unsure what other pattern is.
You will be very very lucky if you can find one.Guys in Aussie(maybe here too) are building Trimatic's to handle around 500hp.Whats your engine putting out!
