On the Dyno today
 

More tuning maybe Saturday (probably Monday) Hope the sheet is ledgable. One down and one more to go :evilb:

Re: On the Dyno today
 

Later pull after some "tuning".

Re: On the Dyno today
 

that is some good #'s like that tourqe curve !!! :evilb: :D:D

Re: On the Dyno today
 

What are the specs on the motor?

Re: On the Dyno today
 

I don't have all the specs in my head or paper right here by let me try. 540 CI , 9.3 to 1 CR 1050 Dominator Comp cam about 600 overal lift. Prototype Canfield heads not yet available to the public (2.50 intake and 1.75 exhaust). These were designed just for a 540 marine engine at 5200.

Re: On the Dyno today
 

Nice tq. What kind of springs and lifters?

Re: On the Dyno today
 

Comp roller lifers , Comp springs , and Comp full roller stainless rockers.

Re: On the Dyno today
 

i second that! :eek: great #'s. whats the deal on the heads. will they be avaliable to the public? would you be willing to post a build spec sheet? curious what cam you have in it. looks great!

Re: On the Dyno today
 

A friend of mine developed the heads for Canfield from the raw castings and he owns the CnC program. They plan to make them available and I'm sure it will be as soon as possible.
Here's a before shot

Re: On the Dyno today
 

cool, sounds like a good friend to have :D . . looks like they will have a winer with those. this head was developed specifically for a marine 540 huh?

Re: On the Dyno today
 

Yep , relatively small ports to handle 540 CI NA at a max of 5200. This combo gives you an optimal port velocity for an cylinder charge and a torque monster. You could also use them on a 502 that you were going to spin a little harder :drink: .

Re: On the Dyno today
 

Wild exhaust ports! Good job!

Re: On the Dyno today
 

They're canted the same as the exhaust valves :cool:
with 9.3 to 1 I almost could but the boost wouls be SO low it would hardly be worth it. Besides , these were designed with 89 octane in mind because that's available most places :cool:

Re: On the Dyno today
 

I'm still curious, exactly what springs and hyd. rollers allowed you to go here w/o vale float?

Re: On the Dyno today
 

Night,
I already stated there were Compition Cams lifters and springs.
Want part #'s perhaps??? :D

Re: On the Dyno today
 

12 pulls later , jet in , jet out , timing up , timing back here's the results :evilb:

637 hp @ 5400 and 679 ft lbs torque@4500 :eek:

Re: On the Dyno today
 

Nice F L A T torque (you almost can't call it a curve!)
I know you built it as a N/A motor but, I'd love to see a mild supercharger set up on it, that thing would be in diesel territory :D
Thats going to make a sweet marine engine.

Re: On the Dyno today
 

Yeah , but twice the rpms as a diesel :rolleyes:
