i have e cam, edelbrock heads, 75mm mass air and going to be having a edelbrock rpm 1 upper and lower soon what would be my best bet... Wouldnt 75mm mass air be matched good with it or should i just go with a 70mm

i have the same set up except for a gt40 intake- i have a 75mm maf. i guess thats fine considering how many people use 70mm and 73mm mafs on nearly stock cars. Are you pleased with your heads philly? got any track times? im just curious cause i havent ran mine yet with the new heads. I think that little Ecam is killing us- I wish i had got a bigger cam when the heads were swapped. Oh well- live and learn.

Yeah i like the power but it seems like its got more thats why im swapping out upper and lower manifold ans going to upgrade my throttle body.. I havent got the track yet but i am soon im going to be buying nitto's soon . What does ur car idle at... i have been having some poor throttle response lately so i just got all new plugs, wires and cap and rotor see fi that helps at all. so what size throttle body do u have?

go 70mm tb with the 75mm mass air. dont need anything bigger than that unless you have heads that flow like crazy.

i have a 70mm tb but its off the car right now cause i need to weld it. i have 65mm tb on there now. my car idles around 1000 or so. Mine hasnt ran right but a few times since the heads were put on. i was happy but it is inconsistent and doesnt run well cause i need to change a few sensors.

if you dont already have it- MSD helps with throttle response also

your 75mm MAF is fine i wouldnt change it

vfast check your pm's

i wasnt going to change the maf i was chaning the throttle body to either 70 or 75
