Well since I am having to tear the motor back down to have it balanced I have been tying to do some dealing to change my combo a little. I wold llike you opinions on this new possible combo.

5-speed SN95 car
I have all forged 347 rotating assembly (now going to be zero balanced)
Stock block
World senoir heads (while it is tore down will have them cleaned up and polished, not ported to broke for that)
right now I have the F-cam and funnel web intake and 650 Holley HP

Since I have having to back track this much, I do not have a ton to sink into it, but, I have the oportunity to do some swaping. I can do some trading and get an Edelbrok Air gap, and a trick flow stage 3 cam. Do you think I would be better off with the swap?

this is for a street/strip. Not a DD but weekend driver.

If not a daily driver and you don't mind a rough or choppy idle I'd say use the stage 3. You'll likely get more out of those Sr. heads. You'll want to check PtV clearance of course with that new cam.

[kmedeiros88]

I just think a you should get a different cam.

[ggreene]

It is not a daily driver, and I dont mind the choppy idle. Just want it to have a good power band. From what I have found out that parker is only good above 4500, I want pwer to be 3500-6500.

make sure the balancer and flywheel are also zero balanced

That cam and intake don't go well together. What you found is right, that intake makes power in the upper RPM's. With the right cam though, you can get good bottom end out of it too. Talk to an engine builder or cam grinder and ask what cam they recommend for the combo.

Also, when you say your assembly is going to be zero balanced, are you taking a 28oz assembly to an internal? If so that's going to take a lot of work. You're better off selling the kit and buying a new one that's already internal.

[ggreene]

The kit cam unbalanced, and I bought it already put together unbalanced. So I am takin my motor to the guy who built my boss's motor, and he is going to take it apart balance and reassemble for me. Guess I should just wait and let him guide me into a better intake and cam combo for me. I just do not have the funds right now to get a custom grind. I thought the stage 3 would go pretty good with the air gap, but what do I know...lol

[fogged306]

Oh ok, if you're just balancing that's different than what I was thinking you were talking about. Just make sure the guy who gives you recommendations on your cam can explain why he chose the lobes he chose. There's a lot of machine shops that can slap a motor together, but that doesn't mean they know what the fuck they're doing, or what they're talking about for that matter. I've been through 3 different machine shops locally before I decided to assemble all my own engines because of their incompetence. You should be able to use that intake with the right cam just fine. It's probably a knock-off PFW, so clean up any casting flash you see in the plenum and ports.

[ggreene]

Ok. Yea this guy def knows what he is doing. He is a high performance engine builder, not just an aswembler. He mainly does high end circle track motors, but calling in some favors to get mine done. So you think i should stay with the pfw instead of trading for the air gap? the intake is a knock off, but it has been cleaned up very well.

[fogged306]

Still, make sure he gives you an explanation of the lobes chosen and why it will work for your specific application. One of those machinists/builders I mentioned does 75% of the engines for a local dirt track. Just because he can put together an engine for a racecar doesn't mean he knows his shit. This guys machine shop has nothing but old school machines in it and he has a "good enough" mentality.. that shit don't fly when you want to build an engine correctly. It works if you just want to throw something together, but if you want it done right, you need a good machinist. Like the saying goes, a good machinst is worth his weight in gold. It's very true.
