well i was thinking about using a nice t3/t4 hybred with a stand alone ecu and converting it to efi with premixed and running like 7 psi i know the compression ratio i am gunning for is 7:1 and its close to it now but i was thinking or useing the 717 block and turn the jugs from a 9?? backwords to correct the exhaust dump (pistons as well) with some work of corse making a water cooled header then a tuneable head to match using a copper crush o ring (i also know im going to have to install an inline water pump to keep the water flowing not to mention considering the boost ill need to look at better seals... anything i missed oh btw if the setup holds under boost what do you think if a b8es ngk plug or do i need to stick with the b7es
