More parts equals more money. try getting cams for a DOHC mustang motor. or even a SOHC GT motor. cams are like 800+ bucks. Ls1/traditional ford small block/traditional GM small block is like 200-400 bucks. you cant beat that

> There is no way in hell a cobra motor costs as much as a LSx motor. Ls2 crates are around 6500 bucks. cobra crate anyone?? the base 350 hp n/a 4.6 DOHC motor starts at 8 grand. thats not even forged rods/pistons or anything liek that or a supercharger. add forged internals and up the compression and hp to 450, and your spending 14 THOUSAND. hello LS7???

> and go ahead and add a blower to a lincoln motor or a standard GT motor or even a DOHC mach I motor that doesnt have forged internals like the terminator… you wont be running anywhere near the power that the terminator has because the internals wont take it. 99-04 Gt’s only max out around 400whp before its not safe to go any further. i did know of a few 450whp builds but who knows how long that will last. meanwhile terminators come from the factor with like 380-390 at the wheels stock and can handle upwards of 700whp on stock internals.

1. you’re right, the cobra motors are very good from the factory
2. cams are around 600 and not really needed unless you just want to spend money on something or want more lope to the idle, most of the builds I have read about are using stock cams
3. factory vs factory, the lsx is cheaper. Ask slowcamaro how much it takes to build an lsx motor, it’s real close to building a ford mod motor.
4. here is the famous whining from the chevy camp about fi from factory. the engines are both very good and are both put in the same type of car, so yes, you can compare them. fords have 281ci and the chebby has a lot more. Ford just chose a better route to making power.
5. the lincoln motors have a very good block and need pistons and rods to take the same abuse a terminator motor can take. complete dohc lincoln motors can be had for 500, add 1000 for rods and pistons, then add your choice of forced induction. You will have to do cam, heads, maybe block, intake for the lsx motor. so yea, they are close to the same cost once you get up there in the hp
