I have looked in magazines and searched on here and I cant find anything that answers my questions exactly. I have a 350 with flat top pistons, Holley 670 street avenger carb, Edelbrock EPS manifold, some kind of stock cast iron heads 1.94/1.50, cam with .447 lift not exactly sure on all cam specs. Wanting to make the most power I can.

The Trick Flow top end kits in Summit catalog look good should I just go with that??

Dont know what parts to buy that will work together, very confused.

Thanks in advance.

If you have Microsoft Excel, here are dyno'd COMBINATIONS. Just find one that has pistons like yours.

link doesnt seem to work?

Need to know specifically what they are. Get the casting #'s, under the valve cover.

Like the heads, need specifics. Might be okay, might be lame.

What are you willing to give up to get it? Fuel economy? Driveability?

You could. The cam in those kits tends to be single pattern/old school stuff.

Bring specifics, including goals, use, etc., and the help is here to clear things up.

The intake is good for mild cams, with powerband up to about 5500 RPMs. The carb is a general-use, does-everything-okay/nothing-well type thing. Need to know what you've got for exhaust and air cleaner, or what you've got planned.

I am willing to buy new heads, cam, intake, carb to make all the power I can, dont care about fuel mileage or none of that. Here is the specs I have on what I got. I want the car to be as strong as it can be but not to where I cant go to store in it every once in awhile, drive maybe 2 or 3 times a month right now.

Heads - Low Performance Stock Cast Iron 1.94/1.50 valves with 86.86 cc combustion chambers and 9.5 Compression ratio. (I was told they was single hump heads) I will still go pull valve covers if you need me to when it stops raining.

Cam - Hydrualic with .447 lift int/exh 230 duration 112.5 centerline 8 valve overlap 1.5 roller rockers

Exhaust - ceramic coated Hedman longtubes 2.5" true duals going to flowmasters.

I have an open element air cleaner with cowl induction hood.

Get a casting number on the heads, your info doesn't make any sense. 86cc chambers is definitely wrong.

Cam - need a part number. Flat tappet I assume? Seems VERY lazy.

I will get number off heads as soon as I can but I dont have a number for the cam, I bought the motor fully assembled.

Sorry, got ahead of myself. Try THIS. It's just much easier to read on one page in Excel format.

Ok, casting number off my heads are 3998993. Anyway to figure out what kind of cam is or is that enough to go on??

According to Mortec they are 75 cc chamber heads "hecho en Mexico" good for low compression

They are typically smogger castings, worst of the worst.
76cc chambers, and do NOT make 9.5:1 compression

Alright I agree they suck so which ones are going to give me 400+ HP thats what I am shooting for is that unrealistic??
