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

I used 48-50 PSI and 6 degrees initial timing.

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.
