1971 455 HO, Is your 71 GTO or F body missing it’s 455 HO this is the answer to your problem and if your Norwood built F BODY Vin ends in 123409 this is your lucky day (YE code ) 191 cylinder heads, OEM aluminum intake and stock 455 cast crank .
The block and heads were sent to my engine shop and were cleaned, magged and a hone was run through the cylinders and they are cleaned up at 0.015” overbore ready for fitting the pistons of your choice. The heads are completely stock, not molested in any way. The intake is the OEM winters piece, NOT one of those repops that there is some negative chatter about.
That is all the parts I have for this engine
