Well not sure if I missed in this combo, if Hughes missed or should I just be happy.
Here's the combo
LA 360 bored 4.040. Machined to perfection, lifter bores bushed. yad yada
Scat 4 inch forged crank with pro series I beams. ARP 2000 bolts
Icon forged flat tops .004 out of the hole(trying for 0 deck, but had to
machine more to get decks parallel and square) Hughes girdle, studs
mains and heads, tight quench.
Nothing wrong here
Eddy closed chamber Hughes Full CNC 68cc chambers
2.08/1.6 backcut valves. Hughes 1.6 rockers with B3 geometry
correction.
Did you examine the S.S.? If it is murdered like mine
and I'm betting it is--nothing will help except maybe more squeeze.
Bullet solid roller .668/.668 259/265 dur. @ .050 108LSA
installed at 104 degrees per Bullet
More than enough to get the job
done.
Ported Super Victor with my old Holley HP950
My old ProForm 950
flowed 955 cfm dry. You should have been able to try the dyno facilities
"good" carb. I have few on hand because I hate to see a customer waste
a session fighting a shitty carb. Doubt your carb is the issue though.
So its a 11.4 o 1, 410, that I thought forsure would hit the 580HP mark. The pull you see here had AFR numbers from 12.7 to 12.9 through the run.
Your not that far off but the torque should be way better-torque curve looks like the induction can't keep up with the cam.
MY thoughts are maybe the Hughes heads do NOT flow as advertised...my dyno guy/machinist HATES the exhaust port. Thank God I got the heads free, but paid Hughes dearly for their CNC job.
The exhaust port is the best part of their machining if its the same as mine, its not too bad-could be better though.
He also felt it needs more carb. Said the old 950 doesn't flow 950. I know that. He told me after all the money spent I pretty much have to find a carb. He suggested BLP. He felt the carb was leaving 20 HP on the table.
Shoulda stuck a real good known quantity on there and found out before spending big bucks on a trick carb.
I should mention that I dyno spinning my MP hi flow water pump AND the last pull we made he threw on a 1/2 inch open spacer and it made 567HP. I have no underhood room for a spacer so I really wasn't interested in going to a 1 inch.
A crazy spacer combo is not the way to get there.
AH yeah. Schoenfeld 1 3/4 dyno headers. Sunoco 93 Premium pump gas. I was not VP 100. Somehow that came up from last year.
View attachment 1715025295 Hate Sunoco always the least power producing at least North of the border.
Well there ya have it. Do you think a new carb can help this thing?
Doubtful.
