I am planning on building a 406 small block with a weidand 8-71 blower. I have built many n/a motors but never a forced induction. I am hoping to reach the 700 hp mark. I am going to run edelbrock victor jr. heads, with a comp cam hydralic roller cam, SRP blower pistons with 8.5:1 compression, 4340 forged eagle crank, 4340 forged h-beam rods, and probaly going to go between 12% to 15% overdriven pulley setup. If anybody has any info about blowers can you please share them with me. Thanks

Thanks I will look it over. I forgot to mention that this truck will be on the street on the weekends. So I am going to try to keep it streetable with 93 octane.

better use copper head gaskets if you going to be over 8 lb of boost
what size pulleys are you go to use and make sure you use a h bearing and not a p bearing water pump should be a hi flow pump and oil pump should be hi vol and hi pressure pump dont use steel blower studs make sure you use the alum.studs
and the piston rings have to be filed gap

Thanks for the info. Dont i need to have the block o-ringed so the copper gaskets will seal properly. Yeah i figured id have to file the rings. Not sure on the size of pulleys yet.
