Real close, 850 HP at 5900 RPM on one pull and 852 at 6400 RPM on the next pull

2nd update. I swapped the intake to a 440-2 and used one of my 1000 HP Holleys with annular boosters this morning. I'm trying to learn how to operate the dyno so the first couple of pulls where not good for several reasons Once I remembered a few things like to put the other three spark plug wires on that I removed while switching intakes yestreday and how to open the existing dyno files from yesterday the motor ended up making 800 hp at 6400 RPM and 753 ft. lbs at 4598 RPM with the 440-2 intake and 1000 HP Holley Love them computer data storage files I swap that carb. off of that intake and mounted the two inch dominator adapter and the Summit phenolic clover leaf spacer and the 9375 HP carb on top of those adapters and spacers and found out that I was out of race gas Them big HP motors use a lot of fuel in a short time So tomorrow I will get another ten gallons of race gas and try that combination and then swap the Indy tunnel ram intake with the two 9375 non HP 1050 dominators and see if the motor will make close to 900 HP and 800 ft. lbs I'm also real curious to see what the motor makes with the 9375 HP 1050 Dominator and adapter with the spacer versus the 440-3 with the phenolic spacer
I'll post those results tomorrow evening. Fun, fun, fun

Right on . I enjoy watching your builds. Theres a lot for us dyno wannabees to learn...
But you should know by now from reading around here that your 440 block is going to snap in half at 900 hp.

J/K.

is jetting perfect out of the box on all these carbs?

what rpm is the pull starting at? what is the AF like across the whole range. post some sheets

where is timing at?

offset rockers or standard?

---

the rockers are a set of T&D that where suppose to be for the SR heads, it looks like the intake are offset like the ones for the 440-1 but the roller tips fit right on the valve stems so The jetting on all four carbs is not perfect, I set them up with the stock jetting from Holley. I have a dual wide ban FAST hooked up to the dyno but I can't seem to get any luck with this unit I can't get the RPM to synchronise no matter what and one side wants to not read accuretly some times
The ignition timing is set at 35, I have not treid it in any other location yet, still trying to get a base line on the carbs and the three different intakes we set the pulls up to be from 4000 rpm to 6000 rpm on the frst three or four break in pulls and then raise the upper RPMs to 6800 RPMs. As far as posting sheets that is something that is not in my skill level or pay grade yet Maybe soon but not today, you know us old guys learn slow on some things

which heads are on this combo? and what are the flow numbers?

---

The heads are a set of Indy SR M.W. port size that flowed 340 CFM at .700 lift on Pettis machines Super Flow 600 bench. I bought a set of the Indy 440-1 last year from a member on here and they look like they will flow a lot more than these heads(pushrod pinch area is a lot bigger on the -1 ) and there 10 CC smaller so maybe they will get put on this rascal if if doesn't split the main webbing while being dyno flog Tomorrow it will get its tail twisted some more

are you gonna try that indy dual quad tunnel ram intake.... how do those compare to a indy 440-3 for power....

---

I am planning on using the tunnel ram right after trying the 440-2 with the dominator adapter and the 9375HP 1050 carb. God willing and the creek don't rise anybody need a good motor, I have one car and four complete motors now and one (B1) waiting to be built

I'm finally getting my 527 dyno tested and tuned this week, it is a 440 block bored to 4.380, 4.375 lightweight stroker cankshaft(65 lbs.) Mopar rod journals, Manley 6.96 long H beam rods, Ross flat top pistons with 4.1 CC valve reliefs in at .007 down with a .039 Fel Pro head gasket. Indy SR heads with Max. wedge port sizes, 76.6 CC on # 1. Mechanical compression ratio off of Silvolite web site says 11.10 to 1 comp. ratio I thought it was going to be higher Next time Back to business, the cam is a custom grind Comp Cams solid roller with 275 duration on the intake at .050, .439 lobe lift, exhaust is 282 @.050 with .440 lobe lift,110 LSA in at 108. Jesel belt drive, [Email]T@D[/Email] roller rockers with 1.65 ratio. Charlei oil pan with kick out and home made crankshaft windage scraper, milidon dual line swinging external system, lifter bores bushed, all the usual gfood stuff. First day of dyno testing was with a 440-3 late style clover leaf plenum intake and three different Holley 1050 Dominators, one 9375HP and two 9375 non HP all with stock jetting and atwo inch clover elaf phenloic spacer. Peak power was between 5900 RPM and 6400 RPM, a local north west brand of 110 octane race gas was used all day and again for tomorrow. I plan on installing a Indy tunnel ram with the two 9375 non hp carbs. tomorrow to see how much power there is in them, maybe the Indy 440-2 with a adapter also, hopefully time permitting and ambitusion(SP?) staying I'll post today and tomorrows results tomorrow evening when I get home. Quicktree, Dram,this is on our local "happy" Stuska dyno Hint, it made more than 1.5 HP per C.I. I'm very happy with the results so far Update, 852 HP at 6400 RPM with the 440-3 intake and Summit phenolic spacer. There was around seven HP and a small amount of torque loss between one of the 9375 non HP dominators and the other 9375 non HP and the 9375 HP. In other words one of the non HP made the same amount of power as the 9375 HP and the other 9375 lost some power, not enough to worry about for me I'll post todays results on my reply to the last post on here today

That compression is 12.7:1 with your figures.

Thanks for letting me know your calculations, I went back to United Machine(KB % Silvalite) site and dug out my blue print sheet and realised that I had put the piston deck hieght down incorrectly the piston on #1 is .007 above the deck so using the United calculator with those numbers comes up to 13.169 and using the figures of .0025 above deck hieght and 77.2 cc for the numder 2 cylinder on the Wallace calculator comes up with 12.87. Wallaces site must need + to indicate below deck and - for above deck hieghts Either way my motor is not a pump gas 11.0 to 1 compression motor like I was beginning to think . Now, if I can just figure out why the tunnel ram set up didn't work What are your thoughts on that(read new post on dyno results for reference on tunnel ram

Brian, I found the problem #1 cylinder has two broken pushrods.I'm going to post that on the dyno test results with a picture.

i knew something was wrong
