Got my Bloomer headed 421 back running.

Vic, number of years back I took off and sold an Eddie top end and headers to a guy. I replaced the top end with W5 full boogie ported heads, a Brett Miller modified Victor W2, and TTI W5 headers.
left all else the same. Erson rockers.
I currently have a bit less cam than what I had then, cars very similar weight, etc…I think these Bloomer heads will end up running as good as my W5 deal did that one year I ran it, high 10.30’s.
Broke Eagle cast crank about this point in the season that year, then built a fully roller X block deal for the following season.
To sum it up, I think these heads are very nearly as good as W5 heads, having had both.

I'm going to install this kit on the front on my AMX. To limit the front travel and hopefully this will be the last piece to to the puzzle. But I also have 50 pounds of ballast that I can put on the front end if needed. Got to check it over this week. Hopefully didn't flatten the new headers. No the heads. When it's said and done I think the maximum hp capability of the Rod Bloomer heads is going to be about 680 hp. Which is a lot for a conventional SBM head. But I believe that I could get 750 out of the W5'S. But to braket race and 6.0 index race I don't think I'll need more than 680.
