How Much HP??
I am looking for some HP guestimates, estimates of what it should be making. I have a 540ci Chev 9:1, Dart Pro1 Heads, Gil Exhaust, Whipple 3.3 Intercooled 10lbs Boost, Full MSD, Topped by a Dominator 1050. I am still tracking down the cam specs. What range of power should that combination produce.
Looking for any and all input.
Thanks

549 lift int and exh.
duration 230 and 236 @.050

My main question is the fact that the builder dynoed them at 675HP at 5600. Seems a little (lot) low. Any ideas??

Re: How Much HP??
The cam is killing it, flat tappet I presume?.....probably could use more carb also....
Motor should be making 950hp easy @6200ish
Whipple claims 740hp dropping the 2.3L on a 500efi....

Re: How Much HP??
my 540 just dynoed at 944hp@ 5600/962ft lbs @ 4400 blowing thru a stock merc plenum and modified 502 mag intake and its a 8-1 motor w/10 lbs boost(procharged M-3). Are your heads out of the box stock or have you flowed them to see intake to exhaust ratio?2 years ago on dyno my 540 only made 629 hp/697 ft lbs tq at 8 psi,the merlin heads were killing it with there terrible intake to ex ratio,i learned alot about importance of flow #'s,especially ex flow from guys on this bd,your cam sounds identical to my old cam too (except your lift is .050 less),i went up to a 234/240 at RM BUILDERS recomendation this time,i think it helped too,Smitty

Re: How Much HP??
Thanks guys. I think I have a larger problem now. About 40 mins into the new motors, I had a rod poking out of the oil pan on the port motor.
Anyone have a pair of 540's sitting on the shelf?

Re: How Much HP??
What did your motor builder/dyno guy say when the motor puked?I can almost imagine too that when it made 675 hp you were told that was safe,reliable hp,am i close?
