That's what i don't know man, cuz the engine came in the car, i didn't build it. I was figuring nobody would be able to give an estimate cuz i can't provide much info, so.....sorry for a dumb question guys.

Re: What do you think my engine is making??? I just want some opinions.

Pull either of the valve covers and look for a number on the heads.

Tell us the last 3 digits. Those, for example, are 416 heads. There's a decent chance you might have those, and those are good heads.

Either way, get us that number and we will have a pretty good indication of, if nothing else, at least its potential.

Pulling the valvecovers is simple, it's only 4 bolts - go check and see.

THat Torker intake is a bit infamous, though.

Re: What do you think my engine is making??? I just want some opinions.

The best way for yo to find out how much HP you are actually running would be to find out how much it weighs, run a 1/4 mile and use the MPH and a drag calculator to estimate it. The e.t. is going to be more tricky to use since the calculator will assume it hooked and left hard.

Even if you had all of the info, all of the estimates you are going to get are going to assume the tune is perfect (which it may or may not be). They will also assume the cam is installed str8 up, the heads aren't ported and the advertised "10:1 w/**cc chamber pistons" are accurate", which mine were way off since the heads them selves were way off in chamber size. Your cam may be advanced or retarded and the heads may have a full race port on them. The are so many variables that you are not going to be able to see without disassembling the motor.

What you are asking is kind of like asking "what color is my wifes hair?" without a picture and telling us shes 5'7, 160 pounds and white.

...or spend $50 to get the car dynoed, that way you'll know EXACTLY what it's putting down.
