if you have 300-400 dollars to spend. i would get a cam. you will gain 3-4 times the power with a cam than a throttle body upgrade.

 

Yes, not really anything cost effective out there intake manifold wise. You are better off with a decent cam and stall.

Would you care to explain this fully to me as several people have seen good gains when used on properly ported 5.3 heads. All of the gains coming on the top end, but fans none the less and yes they will lose bottom end most likely as I had mentioned. I agree though not worth the money.

As for the idea of FI builds making good power on the stock intake that is like saying people make good power on the stock cam or stock heads, sure they are making good power, but why have a restriction in place like that. Some have reported in pro charged setups making more power on lower boost when switching to the Nnbs intake.

Stay away from that 85mm option. You will make equal power with less headache via a stock ported tb. They sell for about $120 from a pro or you can do it yourself if your up to it for free.

 

I did not tell yall I already installed the 210/218 .551/.551 on 116lsa (.584/.584 with 1.8 rocker ratios) with milled .03 862 heads

Love this cam for a dd mild build so much tq

I'm all about tq seeing as I hardly take my dd truck above 3000 rpm and pull a boat during the summer

I would like to run a turbo later in life making 6-8 psi I think when funds permit I will upgrade the intake along with injectors and fuel pump

For now I will keep the stock intake.

No more bolt ons I have done every possible one it seems like

I diy ported/polished my stock 75mm throttle body real even didnt notice to much other than a lil more throttle response

 

Will have dyno #'s this summer. I got an hp tuner street/driving tune no dynos
Have to wait for the semester to be over so I can go back home to strap it on a dyno.

Changing the thread for a minute
My numbers before the cam 274rwhp and 336rwtq were on a mustang dyno

This shop moved to a new location to far away, so now the only other shop is a dynomax

Is it true dynomax read 10-15% higher than what the truck is really producing?

 

I would say the next best thing you you would be to get your heads worked. I would bet you could get them milled and a good port&polish for under $800. If they are milled .030 and the P&P is good you could pick up good power down low and thru the whole power band.
