Re: Converting a standard 200 barrel to small block

why cut up the base gasket ? Rayspeed do 66mm head gaskets for the RB 20 in many sizes that would do the job and myself would get a 175 head reprofiled .
Iv done this conversion myself using a 200 rapido and an Autisa short stroke !

Re: Long Conrods

I bought a Malossi reedblock to go on this but I think I may need to get something bigger to run a 35mm airstriker ?
