Hi, Dont take this the wrong way, but if I think logically, your current combo B1 combo runs mid 7.30's to Low 7.40's, your current Predator runs .3 - .5 secs quicker, which would put you in the 7.15-7.20 range, which is where you want to be.
For commonality, why wouldn't you replicate what you have & build another Predator motor ?

Sell both and build a huge hemi 99? I'd say sell it and build another predator combo, as stated above, for commonality purposes.
11.48 @ 120 with a 1.80 60' 318, stock 1.88 heads, stock 904, Pump Gas, 13 lbs of boost.
9.94 @ 134, 318 on pump gas, 14 lbs w/ Eddies, transbrake 727, 3600 lbs, 3.54 gear and 28's.

If you plan on racing for a long time, classes are going to get faster so the move to a Hemi99 style motor makes a lot of sense if it doesn't kill you with cost or maintenance. How fast was the class you want to keep up with five years ago? Time goes fast!

The problem with the Hemi99 is, it costs $55,000-$60,000 to build a 650" Hemi. And as you've seen here, they make 1360HP which is very impressive, but totally out of reach for me finacially. If I can't make the show with the predator, I have 3 options...NOS, Supercomp, or GM 5 inch bore space motor. There is one other option and it might be the best....take up fishing and golf again.

See what the new combo actually runs and take your decision from there, 3 or 4 tenths at your perfromance level does not come cheap. But you knew that already good luck with the new bullet

Tom the 99 parts are out there cheap if you know where to look. The only stickler will be the block. The rest of the stuff can be had for a decent price if you shop around. But you will spend some coin. Keep in mind though you can build 550" with available parts and blocks which can be had very reasonably.
If it were me I would build the B1 and make it able to handle a decent shot. After all this is a backup piece right? You might be surprised how fast it can go with a 300 shot or better.
Even at 550CI it's a very peaky combo, isn't it? Educate me but I'm thinking tyhe smartest thing us the NOS. I just don't want another variable to deal with while bracket racing. Pending the pricing Steve gives me, I'll do another Predator if I can afford it.

Tom, No doubt it would still be peaky but I think with more stroke and a little less aggressive cam profile maybe they could do well. A fellow member here has one but never really heard him post much about it.
I still think for a back up piece building what you have for some spray is the easiest, quickest lest expensive way to go and done right might be quicker and more consistent than you think.
Al, Will you be bringing that car with the hemi to MATS?

Can you give us a detailed description of your current B1 combo?

Intake? carb-s? headers? rpm range you run it in? any Hp and Tq numbers? Piston ring combo? cam lca? valve spring type/size/manufacturer? rocker type and ratio? pushrod size/wall thickness?
I'm just curious if there's something that can be done to your combo during freshen up.
