i am looking to get rid of a rattle i have in my car in high rpms i dunno what it is its a serious chatter /rattling noise i belive its coming from my bottom end i am gonna get it fixed but while its apart what should i do i wont heads for sure what type do i need to get what would u recomend also while i am in my bottom end it would not hurt to do a lil upgrade i would love to be as close to 500 rwhp how can i make those numbers with out spray/turbo or super charged please help and also what kind of money am i getting into budget 5-6 thou

 

Budget?

 

Yeah it all depends on your budget.

The cheapest route would probably be a forged 347. But its still not THAT cheap.

 

maybe 5 or 6 thou

 

a lot of looks no helps man this sucks

 

You can definitely do heads/cam and a forged rotating assembly for 5k-6k.

 

i allready got a good cam u think i can turn over some 500 rwhp on 5 g i think the ratteling is my pro 5.0 shifter

 

500rwhp on a 346ci is pretty hard without any power adder.

You can come close like 460rwhp-470rwhp a little easier.

 

yeah that would be great i am 401 rwhp now 475 would suite the hell out of me i would love to make the pro 5.0 a lil more quieter never no might throw a hundred shot on my car just dont no if i could do that to her

 

500rwhp out of a n/a 346 will take quite alot of work. It can be done, but it is a max-effort build and probably wouldn't have the best street manners. If your budget is 5-6K why not build a stroker? You can get a forged 383 rotating assembly from tsp for $1800. After bearings/gaskets and machine work you might have $2300-2500 into the short block. Add a nice set of trick flow or afr heads and maybe a bigger cam and 500rwhp is very attainable and street friendly too.

 

I'm with him ^^^ stroke it, and throw on a nice set of heads with your fast 90 and lt's and you'll be at your goal. Also a forged SB will take a 100-200 shot of go gas with out even batting an eye, if you get board, lol.

 

dam thats some serious speed sounds like a goal i need to reach a stroker motor i thought was much more exp than that what about that rattle noise u think its my pro 5.0 its getting louder and louder i am really worried about that
