Tell more. Did you install the cam straight up, what's your timing, what ignition, exhaust? Trans and gears? Vehicle information, weight, etc.

my guess would be, you need more cam and a better intake (Performer RPM)
I think the heads are OK, but I'm no expert
there are some more guys with better info, around here

Thanks alot for the replys, can anyone recomend a good book on porting and polishing heads? The other problem i think i might have is hood clearance with a bigger intake and i dont want to change the hood.

Get a RPM style dual plane hi rise intake and 750cfm carb.

re-curve the distributor for 24deg initial (at idle) and 34-36 total (in about 2,400 rpm.)

get a 10" 3500 stall.

Degree the cam to verify valve timing points. Move it if necessary.

2.5"-3" pipes and flow-master mufflers

i think the heads are fine, i've seen them make killer power out of the box.

the heads will have no problem with 400hp. the camshaft can get there too. the induction and exhaust could use some work. more initial timing will help low end torque but won't change peak HP.

Heads are not the hole issue.

the carb and cam are moderate. Not capable of making good solid HP.

A better cam and carb will make better use of the heads.


Your build is moderate build, your only going to get moderate results.

IMHO

You need to start looking at other things before you do anything with those heads. Maybe the advance in your new distributor is sticking, or the secondaries aren't working, etc...

You should look for a place that will dyno tune it as it is now

i would go with more cam to. the one you have is on the small side for my liking.

The RPM intake is my least favorite. Never made more power than the perfomer on mild engines.

Using the entire Edelbrk RPM package it works like a fine tuned instrument.

The torquer 2 is the -6000rpm low rise single plane. If your build was between the performer 350 package and the RPM 350 engine package, that is my choice. Fits under a lot of the low hoods.

Wrong carb, wrong intake. You need a 750 on an RPM AirGap.

Is your cam the XE268? If so, see the second combo- http://www.ryanscarpage.50megs.com/combos1.html

BTW, that's brake HP, not rear wheel HP. No way I see that cam making 400 HP w/o a lot of port work to your heads, better induction system, bigger exhaust system. Or better heads to begin with.

Now, if you have the roller version that's another story. Enough cam for 400-plus brake HP if you have strong heads to go w/it.

What are you basing your performance on? Have you been to the drag strip to get a quarter mile MPH and ET? Or are you judging it by the seat of your pants?
