Just curious as to what the best base timing setting and fuel pressure setting has been for you guys with a ZZ4 cam and stock 22# injectors for a 5.7?
Its is in a ZZ4 short block and the heads are 64cc and have been fully polished as well as the stock TPI intake has been ported out and polished and has headers.
Thanks

Thanks Kevin, thats exactly where I'm sitting now on both accounts but still need to adjust IAC and TPS next if I get the valve cover tops sealed.
