Street engine or race engine? Tony said typically these street engine low compression deals with alum heads are turds? What spring pressure, size headers, cam, compression ratio, head work? weight of your car?

Anyone else Street engines?

NOT a street engine - -9.2 cr with wideports flowing 380, spring pressure is 410 on the seat with 2 in primaries lift is over 700 and duration in the 270 -280 range, 525 cid and depending on how I winter - 2650 to 2700 lb with DFI. Our numbers say we are at aprox 1900 hp at 24lb boost - and that corilates to 6.60 with a 2700 lb car - as we are ramping in boost - we are making less than that early - and prob more than that at the top.
