Anyone using one in 950ish HP 555? Looking for some real world experiences. I am guessing they are made off shore for the price point I see them at. | ||

I have 565 with a Manley rotating assembly that I got in a Facebook raffle. I've put 300ish runs plus whatever the previous owner put on it with no problems so far. Denis LeBlanc | |||

I hope you're guessing wrong! It'll only move the giant sucking sound doomsday clock closer to midnight, if so! Fact If I were you I'd find out for sure beforehand. | |||

I have Molnar crank and rods in my new 555... 103 runs and the rods are still bolted to the crank. Friend of mine is building a 632 and is using their stuff too after seeing mine. I’ll buy it next time too. I opted for the power adder rods for the small price difference. | |||

Me too! Perot was genuine in spite of both Clinton and Bush professing globalism was just a matter of job retraining, which was fake! | |||

Check with Bullet Cams Jake. This is a made in USA 4.25 crank I bought for a guys dragster from a long time friend from Lunati who moved over to Bullet. I'm pretty sure it's a Callies Magnum he would only say it is good **** put whatever power to it you like. The chinese crank I switched out for this bullet crank had a crack which nearly destroyed this block. I put this block in a paint oven (aluminum block) to get the clearances exact (running temp) as a result of the line bore being iffy at the parting line on the #1 main cap as a result of the cracked crank just about ruining this block. We had to fanagle half shells to get clearances but it's running to this day 4.70s - 4.80's. I was pretty happy we could save this block for the guy to get his daughters out there racing together. A block may have set that back a few months I'm sure. | |||

I will most likely put another Callies Magnum back in it. Thanks for the input. | |||
