SCT BA2400 meter and 42# injectors.

[Dark_5.0]

This is what my tuner told me to buy for my 331 stroker it should make between 430-460 flywheel HP naturally aspirated.

If anyone has anything negative to say speak up before I drop 500 bux on this crap.

Good choice, it'll give you some room to grow when you decide you need more power. What's your combo going to consist of?

Yeah I'd say. Have you thought about getting a custom cam?

I had a custom cam in my 302 and I didnt think it was worth the cash.

I invested in some engine simulation programs and that how i came up with my cam choices.

I'm gonna go out on a limb here and say that IMO, 42's are a bit over kill if your staying N/A 331. You usually don't want to run injectors below 20% and above 85% duty cycle. I run the 30lb's and my PMS reports that I barely hit 65% at times in WOT.

I typed in your 460hp N/A car with 42lb injectors on the websites fuel analyzer and this is what is came back with. I understand this is based on a stock compression 302, but it's still going to be the general idea. Hope this helps.

Total fuel consumption under wide open throttle: 230 lbs/hr
Minimum fuel pump volume required: 138 L/hr
Optimum fuel pump volume required: 165 L/hr
Injector size needed at stock pressure (40 psi): 33 lb/hr
Pressure required on current injectors to simulate needed size: 24 PSI
Your current injector status is: OVER INJECTED
