I haven't seen many of this exact combo out there as far as results go maybe I missed them in my search just wanted to know how that combo ran, dyno numbers, track passes or just comments on the setup in general.

 

Very similar combo being put together at the moment 230/238 cam except its not an EPS cam and the valve events are probably different than most would run and hand ported dart225 heads. That setup is really good if you do some cleanup work on the heads and the cam is good if you don't go with a large LSA. Well say this setup is on LS2 or larger motors. If you can't make 450+ to the tire with this setup your doing it wrong any trans and rear end combo.

 

I've seen eps 230/234 with advanced induction 243s make 460rwhp,also 228/230 with tfs 220 make same power so I think you will be in the 440-460rwhp but regardless what the rwhp is I think it would make a good strong set up

 

AI heads, info below.

 

I'd ask Geoff to see what he thinks. Those valve events may or may not be optimal for those heads.

 

When I spoke to EPS briefly they recommended the 226/234, with the cast 220s. Yea I see that cam a lot in LS2s guessing because of the extra displacement. Im going to get them touched up by BTR before there shipped out. I was also curious as to the valve events I read somewhere that if you have really good flowing heads you don't need the extra on the exhaust side.

 

The is more to it than just saying a good flowing set of heads doesn't need more exhaust duration. What happens is it causes your EVO to open earlier which is good for making more high end horsepower and carrying your powerband up top longer or extending it. Its a balancing act of going to far or going to little for the intended application. A good flowing exhaust port that maintains a good ratio with the intake could do with less like the AFR heads and carry the powerband well up top or it can be compression related to bleed off just a slight amount of compression which won't have hardly any effect on power other than carrying horsepower better in the upper rpms. You could still have a decent port, but are spraying nitrous at it and the extra EVO will help you make more horsepower. I will be flowing a set of PRC as cast 225 heads here shortly and see how much work needs to be done to the exhaust port. I would ask Brian, if that is who you are going to do the work about the PRC heads. I am sure he's willing to touch up any head you would like to send him.

 

OP, why not just have Geoff or Brian set you up with a custom cam? I think that would be the best route to go.

 

Yea thats the plan, just wanted to see if anyone on tech had some good additional info before I make the call.

 

Having one hand in the pot so to speak is really the best way to go. Since Brian is hooking you up with the heads and valvetrain components, makes sense to have him spec out a custom stick with all the correct valve events for those heads, as well as how you intend to use the car and desired power levels. I'm looking forward to seeing how this all turns out for you.

 

Both are great and know what they are doing but have completely different views on cam timing and valve events.

 

True, but neither of those guys will lead you in the wrong direction.

 

I agree with the calling BT or Geoff at EPS posts but in my humble opinion I dont think you're going to get a cam with that big of split. Big split cams are usually reserved for heads that dont flow as well on the exhaust side like stock ones. Once ported or aftermarket heads come into play you can cut the split down a little and not lose anything. Just my .02

 

I had a 230/238 112+2 and it drove nice with a good tune and 3.55's also made 478hp with trickflow 225's
