just wondering if this setup that I'm in the process of doing is going to be to much for a stock motor? I've got bbk 1'5/8 long tube headers and matchin off rad x-pipe,mac underdrie pullies, mac direct shot cold air, accufab 70mm throttle body, c&l 76mm mass air, 24 pound injectors, and a elerbrock rpm performer two intake. My question is more geared towards the throttle body,mass air and intake are these to big for a otherwise stock motor should I go with 65mm throttle body and a 73mm mass air? or will my cobination work out and run fine. any suggestion are welcome
thanks

why would you get all of that with stock heads? You won't need the injectors and you won't benefit much from the rest.

Agreed. Invest in some good heads if you really want to haul. The RPM 2 will not be worth the money with the stock heads. Even keeping the stock cam with good heads will make good power.

buy all the stuff and put it in a box somewhere until you have ALL the parts you need, then put it all together at once

Headers and intermediate pipe will be a nice addition.
C'n'L will make a nice addition, but, I'd order a sample tube for 19lb inj's for the time being, as, there is no need for the 24's, not sure you'd get a nice spray out of the larger inj., but, I'm guessing.
Personally, I'd not bother with the intake, it's runners will be much larger than the ports on the heads, creating a ridge/ledge, and, that's not desirable. That, an I'm not sure the stock cam/heads will benifit from a short runner intake. I would think that intake would provide lazy air given the stock cam/heads.
70mmtb is much larger than the opening on the stock intake, so, again, ridge/ledge. That, and, the stock 60mm TB is plenty to feed stock heads.
Now, if you were to try the rpm intake and like it, then the 70mm tb would work.

thanks clean lx so your saying for now just keep the stock injectors forget about the intake for now and get a smaller throttle body would a mac 65mm throttle be good?

just run the stock tb for now (you can go well into the 12's with the stock tb) and hold onto the 70mm until you are running an intake other than the stocker.

i really don't think the 24's are going to work well at the ~220hp range... so, ya, I'd keep the stock 19's on for now.

I don't know what your future plans are, but, that rpm is a lot of intake. Personally, I'd consider trading it for a standard performer. that would work well with your 70mm tb and stock heads... and... support some decent heads on down the road.
