65 Hemi OP super stock 6 Joined: May 2008 Posts: 984 San Diego CA	I have a 64 Dodge that I want to start 275 racing. Currently a 583 B1mc motor but the rules are SB only for boost. What is the best heads and block to use for a boost combo? What parts are most available on the market. I have never built a SBM. I have always had BBM. I am looking to see if it makes sense to switch.

They are ongoing projects!

PM me if interested (its in the for sale section) Last edited by MR_P_BODY; 12/30/13 11:20 PM.

I know someone with 3 sets of w7 heads and brand new blocks,i saw 2 blocks in the garage recently.

Now I don't know if this is due to the material the head is made of, amount of bolt retaining the head, quality of fasteners or all the above. But THITEK has a G3 head that is physically beefier.

I know a local guy makes 1800 HP with a SBC and runs 4.50- 4.60s. I think I may be out gunned with a mopar. I think there is a guy in TX with a new Challenger with turbo w8 that may be in the hunt but I think it would be cool to do it with old metal mopar (64 B-body).

I'm not sure if the open deck r5 block will take a ton of boost. Maybe with darton sleeves it would work? Or if you could get an xr block you could use a p7 head? The duster from Texas (marty) doesn't have w8 heads. Now it's got billet p5 heads.
