If it didn't break any parts at least that's a good,that means all you need to do is a little tuning! Don't over look the Torque Converter you would not think it would matter in a dragster with a Big engine but it does.





The torque converter is right where it needs to be when jumping around in elevation, and I agree, it can be the most important part of the equation. I needs some tuning for sure.

Can you post the incrementals like 60', 330', 1/8 ET/MPH , and 1000' as well. Or a pic of the slip.
Congrats on a good 1st outing!

I'll try to go with what I remember, as I just got home from the rain out of today. The 60ft was 1.12, the eighth mile was 4.820@144.4 on the last pass, 1000ft was I believe 6.30. It only had 7 inches of vacuum, was 11.8-12.4 A/F, and the 60 ft was .030 slow. Needs some tuning. I fixed most of it today but probably won't get to try it out till 2015. All I can say is, the power is there, I just need to figure out how to apply it. I struggled with the B1 deal for a while before so this doesn't surprise me. Thanks to Boatracer 572 for screwing it together for me and picking the combo.

7" of vacuum, would make a nice street engine with that amount of vacuum wouldn't it?

With a correction factor of 1.22, you should be at least 1175 hp..

That's actual hp based on your ET and MPH..

Also, your humidity was way up there.. I see 1200+ hp out of this in good conditions....

Actually Chris, the correction factor was almost exactly 1.22, it was 1.24. That's what HP Boat racer was after and predicted. Thank God at least someone knows about these Predators! Indy was absolutely no help. They only care about what they're selling at the time you talk to them, information is nil. The cam was also spec'd for a 540 so, with an application selected camshaft, it should make more power.
Also, compression was down from where we wanted to be because we had to cut the domes off the pistons, as they were made wrong. I sure liked paying extra for for something I eventually had to pay more to have removed.
Oh well, I'm happy it is rocking now. Also spent a fortune on head gaskets, Indy wasn't willing to help, just dictate what should be bought from them, of course. Hemi block with Predator heads, is not as easy as it sounds, believe me. Flat out gaskets has them now though. I know, I helped in the creation of them!

Nice build, I'm glad to see it making good power. Good job to all involved.

Considering the weight gain, that I may not be able to confirm until I get to another divisional and that I was in 7250 ft corrected altitude, yes. I'm pretty sure with different gears, possibly a different converter, better A/F ratio, a chance to play with tire pressure, different headers, I'll be able get .15-.25 out of it. I think Tony's prediction of 1200+ HP is spot on. Thanks for all the comments guys!

Where did all the extra weight come from? The iron block?

Yep, the aluminum block was 140#, and the iron block is 300. Then you have bigger, heavier heads, steel rods, heavier center counter weighted billet crankshaft, and 2 carbs. I'll need to weigh it at another track to really know though. Some said the scales were 60#'s light, and I heard yesterday it was only 10#'s light. The car weighed 2000#'s so I'll re-weigh it at the next race.
