Was a pretty good day, my engine out of the box was pretty much spot on. The only thing we did that made more power was timing. The carbs i got new from bigs performance. I gave them all my engine specs and the carbs where dead nuts. We jetted up just to see what it would do and we lost power up top. When i got there steve asked if i had set lash, i said yes and he asked if i wanted him to run through them. I told him to go ahead and man that guy sets lash fast! He probably set lash on 4 cylinders faster than i could do 1! One cool thing was that he stopped and took the time to show me his method and what he likes the feeler guage to feel like. We ran through the break in and i was nervous as hell. My knee's where shaking and i was hoping it was going to stay together! We got through breakin and made a few runs and the first thing we noticed was that oil pressure was dropping off around 6000 RPM. He thought i had too much oil in the pan. The pan is a b&b 10 quart pan and i had 10 quarts in it. We dropped a quart and the problem got worse. Steve was thinking that the oil pumps bypass was possibly kicking in. We decided to do a oil change and put in 8 quarts of lucas 10-30 synth oil. This dropped the oil pressure accross the board 8 PSI (had conv VR1 20-50 in it before). We then processed to make passes increasing timing, the motor made the most at 34*, at 36 it actually lost a few HP. We then started messign with jets just to kill time and see what changes it made, we jetted up and lost HP, then jetted back down and the dyno broke!

The end result, the motor made 671.9 HP and 637.6 TQ

I saw the video for the first time today, before I read the thread, and I must say I was glad to see what I saw...I was really afraid you lost your engine.
Good job, man. Now you can relax and enjoy the fruits of your labor.;)
Oh yeah, what oil filter are you running?

No, i have a new Stainless AT A in it. I'm going to run it and see where i'm at RPM wise and then have it cut and detailed to where i need it. Alot has changed this winter. Bottom straightened, set pump back 5.5", shoe, ride plate, impeller, inducer and now motor! Was running 85 MPH last year with an engine that i figure was putting down some where in the 500's HP wise. I'm really curious to see what she does now!

No. You must practice. "I leaned her down and then she twisted the shaft right outa the dyno."

Write this on the chalk board 100 times.
LOL
lol, that'll be what i tell em. Poor westech though, i warned them when i got there. I said i've been fighting this build every step of the way... then i break there dyno. Next build i'll call steve and he'll be like sorry were booked forever! ;)

Thanks Scott, it feels good to know this thing was run on the dyno and looks to be strong and holding up. Now i can drop it in and beat the hell out of it.

I've been running Wix filters, i ran them in my last build too. PN# i've been running are 51061 and 51060.

Yeah, me too . I forgot you did do a ton of work on that baby she'll be a different animal.

What did you put down for uncorrected numbers Shaun? And what carbs and how much did they cost? Did you make any partial throttle pulls?

Awesome build bro :)devil
Tony,
Take the total amount of fuel/#'s and divide that the by the BSFC number. This will give you the raw number in HP. Then divide that number by the correct number and that will give you the correction factor %.

That oil pan is probably the best pan on the market for the price, so my thought is you might be flowing more oil than the filter can handle at the upper rpm's, and with no bypass, you're starting to collapse the filter. Try a K&N and see what happens.

I'm running a melling HiVolume pump, is there a chart showing what these pumps will flow at a given rpm range? We went through the nobypass with my last build and the end result was everybody saying to get ride fo the bypass...
