12A max power
How much power can a 12a really take?? I have a drawthrough carbureted turbo setup on the stock 12a block, with water injection, and plan on 300 hp. Does everyone think it can take it? If it doesnt, I can use a rear cast plate from a 75 13b, which are supposed to be stronger.

Yeah, shutup kid.
It should take 300hp fine. Just make sure you do not let it detonate or run lean. I learned the hard way, and now my backplate is cracked and I have to take my car apart AGAIN.

dude you so got it. just make sure you NEVER RUN LEAN and do not detonate as said by coldy13. it's all in the tuning man. remember you can blow your motor on 6psi or 30 psi. T U N I N G! ! ! ! ! get it on a dyno with afr readings.

My buddy has a wideband 02 sensor.
But, It was my dumbass using the stock fuel pump. When the float bowls went dry, i detonated. I got a holly fuel pump now, it should be ok.

Carb's don't need a ton of psi. But you want to look at the gph, that's the thing that'll keep the float bowls full.
I'd estimate maybe 7 psi at 20 gph? Someone tell me if I'm wrong. BTW, if it was me, I'd go with a blow through setup, and pressurize the carb. Jetting is so much easier.

it runs fine the way it is, plus, its already jetted correctly. The holley pump will easily supply enough fuel for the setup. I was able to go up to 140 mph before my floatbowls went dry, that was at 240 hp.
Anyway, i finished streetporting one of my cast plates today, it looks awesome!! I talked to some more people, and its not the webbing that strengthens the common braking area on the 12a's, its the thickness around the outside of the upper dowel pin. I am going to have it brazed to help with the strength.
