Highest flowing sbm heads?
I think with 13:1 plus and a few other things could get those heads very close or at 700. What do you think ?
I am a big believer in time slips with mph on them, and not so much dyno numbers.
That said, I see Rod Bloomer just spent the last several days on the dyno at BES.
He had a 416 on there with his Bloomer heads, made 680 and 590 torque.
don’t know any other details on the motor, other than they ran it on 111 for consistency, but Rod thinks it would be fine with pump gas.
the pull at BES is on his Facebook page. Motor sounds nice at 7k:rolleyes:
For comparison sake, the 421 with bloomer heads made 657 on the same dyno and has been 6.08 at 112 thus far at 2920 pounds. Still has 1 5/8 headers on it, he is getting new ones made. Rod sold the guy the complete motor that was on the dyno that made 657, and guy stuck it in his AMX.
man, my pooch is really a pooch, definitely needs some tweeks:BangHead:
