i will have a 351w efi on my engine stand pretty soon. im going to do some mods and i wanna know how much horsepower and torque estimation ill get when im done, if you have any mods you think will give me some good power for a good price let me know, and how much hp/torque does this motor have stock?do i need to get a cam? i wasn't planing on it but if i have to i will? here are the mods i was looking to get done. vv

What vehicle is this going in?
What year is the motor?

All stock the motor was rated at either 200hp/300tq or 210hp/325tq depending if it was an early(pre '94) flat tappet or later(post '94) roller cam motor, but that was also with the cork like stock exhaust system. Headers and exhaust pay big dividens on these things but after that you need to go inside the motor to see significant gains... which means a cam and heads.

Nice parts that are definitely an upgrade from the stock pieces and will give you plenty of future upgrade room.



A complete waste on the motor as it exists since it makes no power above 4000rpm and won't until the heads and cam are changed.


Longtubes are better and these are only good for a Mustang.. won't fit a truck.



No performance gains to be had here so unless you don't have a distributor for the motor don't bother with this.



You can't use these unless the vehicle is MAF and you have a tuner, and you don't need them until the cam and heads are upgraded.

 

yeah im not sure what im going to put the motor in yet but either a foxbody or a ranger. and im pretty sure its a 1994. how much power increase you think ill have after the upper and lower intake, and throttle body and some long-tube headers, what kind of numbers will i be looking at?

 

With an otherwise stock motor the intake and exhaust are really just goin to polish the turd so to speak.. so it won't be anything too dramatic maybe something like +20HP/TQ over stock and most if not all of that will be because of the headers and exhaust. If I were to suggest you do anything different it would be to put a cam in the motor now instead of some of the other parts like the pulleys and distributor that won't do anything, because you will see real and substantial gains from that right away(+40HP/TQ) and it also means you don't need to go inside the motor again when you get around to putting heads on it.

 

Okay yeah that sounds Like a good idea, I'm going to take your advise. Thanks for the advise!!! I appreciate it

 

what kind of cam should i get?

 

The cam you pick very much depends what vehicle this goes into and how you use it, I wouldn't suggest the same cam for a street driven car vs a truck and those would be a lot tamer than if you're gonna race it, and it also depends what EFI system you have to work with too.

 

You may want to consider in the future a higher lph fuel pump,regulator that BBK sells. And Holley has a wideband O2 controller W/gauge that comes in handy when tuning.

 

You are wise to do so.
