If boost will be down to the 6-8 range, there will some areas of fudging (doesn't have to be "dead-on") if boost is going to be higher, consideration of cam selection needs to be reviewed and is more critical. Propane is higher in BTU's which represents higher octane. Remember it is a dry fuel (vapor) so your consideration of where to introduce the LPG into the system should be thoughoughly thought out.
thank you for a speedy reply with worthy context
it has been suggested here in oz that i might have to consider using twin mixers and gas carbs to feed the fuel, i am tryin to think of a way of using a twin throttle body and and some other form of entering fuel to the motor. what sort of heads would you suggest aluminum or cast with stainless valves.
what size chambers would you recomend
