this is a a stick so idle quality is of little importance, and low speed should not be a prob... have great gearing... i know heads seem like they would be lazy but i am gonnn move rpm range up alittle and make it work, bet it works real well.... thoughts??? so... goodwrench 350 64cc 225cc patriot heads xs282s solid flat tappet 244/252 @ .050 .520 .540 110icl vict. jr. or team g, ( i have both laying around) 1 3/4 header with 64cc should be around 9.5:1 im thinkin good torque around 4500 peak hp around 62-6400 maybe higher???

actually 106icl on a 110

Well i think the intake would be ok for what your want the heads idk i think they are a bit big for a 350 even given your high RPM powerband but thats my oppinion. The cam i think is a bit small for the earlier two parts mentioned only having a RPM range of about 2500-6500 about. I think the compression will need to be bumped up a good bit to deal with the cam thats large enough to match your other parts. The GM goodwrench motors rev limit would never allow you to access the RPMs that your building this motor to perform in unless heavily heavily modifed. Im thinkin your power band is going to be like 4-8k about so if your truely do have no intentions of ever driving this on the street under any circumstances what so ever properly put together would make a interesting combo for a race only motor. Although i think you may want to seriously reconcider. If your really want that much hp you would be better off swapping to a larger motor.

i did swap to trw forged pistons and arp studs on nains and rod bolts....

i thought that 6700 or so would hold.... does have "pink" rods...

If you got the heads already, then use them. If you have a choice, especially for a heavy truck, I'd go with smaller intake runner heads. Not sure you could use all of that intake runner even if you had a very light vehicle.

This is one of those situations where it's FAR better to go too small than too big. Heavy vehicle, modest displacement, compression that's borderline low for the cam. All that points to smaller port heads. Frankly, I doubt you'd lose ANYTHING off peak power stepping down to 195-200cc port heads, and you'd pick up midrange torque in the process.

Well for starters its more than just the bottom end and hopeing getting everything forged will make it tough enough for thoes speeds. Theres also weight of your rotating assembly to concider. The "pink" rods are a performance rod but at the same time there kinda old school and tougher options exsist. I dont believe your bottom end would withstand that much power at thoes RPMs for any extended period of time. I could always be wrong but thats my best guess. Assumeing for a moment however that the bottom end was strong enough for 6700 your build is building power outside of the RPM limit still. Ide guess on thoes parts with a more appropriet cam you could build power to 8K. You would acutally have better performance choseing smaller parts because the only place where these would perform larger than a smaller set is outside of your rev range anyways. Theres also the valve train to concider and even with solid lifters im not convinced that reliably hit just under 7 K. Theres also the oil control to concider. At thoes RPMs you run the risk of sucking the pan dry. The ignition system would need to be totally upgraded to perform at thoes RPMs. Fuel delivery would have to be beefed up conciderably. Lets not forget reliability. This could not work as a streetable truck even just to drive down to the track to race it.
