Hopefully the heads flow as predicted I e. Around 290. Otherwise it doesn't offer much against the competition. I think afr released another Edelbrock copy recently and it's like Zzzzzz Zzzzzz Zzzzzz
I was just looking that up yesterday.
Looks like the speedmaster casting and they put their own valvejob and hardware in it. So a 260cfm head unported similar to the promaxx variety.
