Bloomer heads
this is Rod’s dyno day at BES on the motor poster tvt59 has been 6.08 with already
“My old 421” small block Mopar on Bischoff’s dyno. 11.6 pump gas with a 263°/ 270° @ .050”solid roller. Super Victor only port matched ( no plenum or runner work) 950 carb and the baddest standard port SBM head developed by Vic Bloomer. Making pretty decent power for the combination. I only caught the tail end of it in the video but, according to Tony, it’s the highest HP SBM (in this configuration) he’s had on his dyno. Made 657 HP and 593 ft. lbs.”
