1st you say you have a 393CI, then you said it put down 420. Now its 125 shot with 530/650TQ.. Just seems to me thats something is up and you might be full of it. You only have 16 post's and you write like your 10 years old. I think I am done with this thread.

Personally, if I have a 393CI and put down 420 I would not be spraying anyhting on it to begin with. Hell my H/C 347 CI puts down more then that..

Untuned stroker with aftermarket injectors and it won't run good, well, that's probably the problem. Click the alpha. sponsor lister at the top, enter your zipcode, and find one to take it to ASAP.

Those inches, that cam, and decent heads should make 475+rwhp with tuning considering you've got LT's and a 90/90. There's really no way to tell, because every car is different though. A cam that size in that motor should make great torque though.

Looks like a magic stick. I would opt for a bigger cam. But that is just me
