ZR440 upgrade question...
A quick question for anyone who has slapped on a bigger top end kit for a 440. What are your expierences with the company you have bought from (D&D, Black Magic....) and what did the kit really end up costing you. I blew a piston the other day, and have some spare cash to upgrade, but dont really want to purchase a new sled just yet. I'm figuring i'll have to buy a clutch kit, maybe pipes, and possibly a few more sets of jets. Any information would be really helpful. (BTW, its a 97 if that changes any of the advice) Thanks.
