Time to make some Power....Advice Wanted.

Pushrods: I'd definately go with the hardened ones just for peace of mind, guideplates would be a nice investment too (bout $30)

Cam: I've got a 302, so I'll let someone else advise you on this one.

Gears: If your 3.00s are open, then a 3.55 traclok should be a great improvement.

Valves Springs: depending on your cam
Rockers: Nice set of roller rockers 1.6s or 1.7s depending on what kind of cam you decide to go with.

Exhaust: Sounds good, I'd suggest the H as well. Little better power and sounds a whole helluva lot better in most people's opinions.

I don't think 300RWHP sounds unreasonable at all...no expert here but Clevelands are pretty spunky from what I hear.

Cam - I would suggest Comp Cam XE262H for mild performance if you are retaining stock converter or XE274H for more power if you plan to keep FMX, would need 2400 Stall converter and 3.73 or deeper rear gears.

I would recommend X-pipe rather than the H-pipe. Summit sells the 2-1/2" X-pipe kit for $90.

Well, if your gonna pull the heads, then I would go with the guide plates and screw-in studs, otherwise just get the hardened pushrods. I would also get a set of roller rockers (I believe the Clevelands came with 1.72:1 from the factory. Someone correct me on this if I'm wrong). As far as valves, i don't remember what they come with but a set of 2.02/1.60 will complete the setup. The 2v heads are fantastic heads (better than the 4v IMHO). These heads will breath into the upper RPMs so a cam with a powerband of say 2500-6500 would be a good choice and will still save the bottom end. As for gears, the 3.55s are good, but if you don't mind it go with a steeper gear, say 3.90 to 4.10. You will REALLY notice a difference. Now that being said, the FMX gotta go. Yes it is a sturdy tranny, but not designed for high performance and weighs like a million pounds. If you want an auto, get a C6 or swap to a 4 or 5 speed (I like the gear bangin' myself). The exhaust will also make a huge improvement since the Cleveland moves so much air, it's gotta go out too. Your headers should work very nicely on the street. Even a cheaper set (Hedman or Flowtech) will be a big improvement. i would run 2.5" all the way back and use an X or H-pipe (I like the X pipe, but they are more expensive). Don't overlook the intake. I don't really know what is offered anymore, but the Torkers for the Cleveland used to be the one of choice for the street (at least the people I talked to). Now obviously all of this will go over $1000, i don't know what you can do yourself, but if you can do most of it (pull and replace your cam and heads, weld up an exhaust, and swap rear gears), you would be close to your target. The more you farm out, the less you can get done. Out of all of these, do the gears and the exhaust. They will give you a good foundation to work from.

I agree with 19stang67, the fmx has gotta go, they can handle torque OK, but past 5,800rpm they blow up (been there done that, and it took my engine with it .. ).
Go with a professionally built C4 or a C6 or move to a Trmec 5spd or 4spd yoploader if you have the bucks.
The biggest single improvement you will make is changing the rear-end gear ratio to 3.55 or more.
If you want to highway cruise with this car, 3.91's or higher is brutal......3.55''s are a good allaround choice.
I run 4V heads on my 351C and love em.... nothin breaths like em ! and power ?
Dyno'd at 450hp & 420 ft/lbs. (6,500 & 4,000rpm respectively).
But that was with new stainless valves, forged pistons, big cam (.540/.560), but it's VERY streetable, not to mention fast !
Make sure you pay attention to the Cam and make sure to buy a Cam/Spring/Lifter kit from the same manufacturer. Don't replace a Cam without also changing the other 2.
