You need to look at the pictures of Wade's heads that Charlie Buck did. You don't soften up those B-1 chambers it will be VERY timing sensitive. Also the right camshaft is a MUST. Nearly impossible to get the numbers you NEED on a standard BBM core. Needs to be 55mm My B1 Original Heads were done by MCH, and were opened up to 76cc chambers and the quench pad was also angle cut for nitrous. With 13.5:1 compression and a 93 jet (250 HP) in an IS plate, that motor only liked 18 degrees of timing when going down the track. Granted, a different cam could have changed that a bit. It was a nitrous cam, and worked well. Also, that was at Bandimere where the air is thin. So, at sea level would have wanted even less timing. I agree with Monte that if you don't soften the chambers it will be very timing sensitive. Well worth the money in my opinion. Mine made 650 to the wheels on motor, and 905 on the 93 jet.

NOS Monte
Where is the perfect spot to install O2 bung in merge collector?
What is the best retard delay for annular fogger?
Same question for plate?
Back together with Charlie's chamber softening and valve job. Only took a couple cc's out of chamber. Nothing else. 48 cc P7. Large step header sound great. Hopefully really gonna free some power on top end. Went testing. A 36 pill in a double cross on a dirt rd. of a track went 5.42. 13.5 a/f very light fuel ring on plug. Saturday starting line was sticky. 32/24 in a wacked off make shift annular nozzle hit like a brick. Having to relearn wheelie bar steering on the big tire. Huge difference from the old 4 jet spreads of back in the day. 12.6/ a/f on fogger. Probably go up .002 on the nos side to clean up. Big thanks on the suggestions from Monte over tge last year or so. The plugs look great so far as timing. This 32 pill with a clean tune feels better than the 40 pills back in the day.
Career best 8.02 @ 169 at 3050# and 10" tires small block power.

Kid installed wheeli bars while I was building exhaust. He asked about a heim screwed out and I thought he was overthinking. Turns out I had a brain fart and the sticks were driving the car hard left. We never made it to the 60 under power. It leaves stupid hard on prepped track. Hopefully make more hits Friday.

Does anyone run a Pro Mag 44 with EFI? Of course. We do as do many heads up racers.
