422 dyno fail
Interesting reading , hope to all works out.. here are some dyno numbers on my two small blocks for reference: my 408 ( R3 block , 4 inch stroke ,Indy 360-1 heads and intake ( pretty much out of the box ) 9.8 to 1 compression on pump gas , 600 lift mechanical cam, Holley 750 hp . 1 7/8 headers ) : made 539 hp and 502 torque / my 367 ( 360 Magnum block , 40 over , 10-1 compression on pump gas , ancient W2 heads, Victor W2 intake, 585/ 595 lift cam, Holley 750 HP, 1 7/8 headers ): made 527 hp and 467 torque. ... 367 in the picture on the dyno 3 months ago... my 408 has been troublesome.. it broke on the dyno a few years ago ( luckily only needed bearings ) .. I have been having problems with breaking the Indy rockers and last year it cracked the crank by the # one journal ( again I was lucky as nothing else got hurt )
