Cobra Engine Build Part 1

This will be the first in a series on the engine build for my Cobra. This is a 351W bored 0.030" with a 408 stroker crank. The intake was converted to fuel injection and featured in a previous video. I will list components as much as I can.

Thanks for the advice. I really enjoy your vids, keep em comin they're very inspirational.

I'm just trying to help. I never considered myself to be very insperational but I appreciate your comments. Good luck my friend.

I just figure that the new 5.0 is still 302 cubic inches just like the old. The only difference that I can see is h/c/i and rpm range, so if I can match flow rates or exceed I should make the same or more. The only thing I can see lacking is variable cam timing, resulting in a narrower HP and TQ band

[CoolCarsHotGuitars]

Not so... A 5.0 can have a smaller bore with longer stroke. There are many shapes a gallon of water can fit into. The flow rates of the heads will determine carb jet size or injector latch time. The variable cam timing is done with a hydraulic phaser. If you have a closed loop OBD II system it could throw off all of the computer settings. You will need to re-program the EPROM for the new engine settings. It's a complex project you're taking on. Good luck.

Thanks for the reply. I'm just trying to get 400 hp with h/c/I. (and exhaust)

And have never built an engine before.... But read A LOT about it if that counts for anything. I don't understand cam measurements and how much of a difference that it will make on the valve end or how to calculate that.

[CoolCarsHotGuitars]

The cam is critical. Slope, lift, duration, and base circle are critical to performance. If you have an idea how you are going to build the motor you can call Comp Cams and they can grind a cam to fit what you need.

The TKO600 is a pretty robust. I'd give their tech support a call and see where they guide you. Thanks for watching.

awesome, thanks very much, i'm doing this same motor soon for my 89 notchback.......a question for ya though, i want to stay manual transmission, and i'm not sure what i can put in there to handle the torque, even the tremec's don't seem to handle what i'm going to put out in torque....600ish i'm thinking

[CoolCarsHotGuitars]

Tough one and a bit risky. Make sure you have enough material and you won't create a hot spot...the piston will melt for sure.

[vbstangin]

I know this is a little off topic but have you ever used a piston notching tool? I'm trying to install a head that some people would say is too big for a 302. And I don't want to disassemble my short block for aftermarket pistons.....
