Budget motor build
I have found a 2003 4.6L 2v explorer engine with an aluminum block for a really good price. The plan is to build a budget race engine with around 300 hp (maybe more maybe less). So far I’m looking at getting VT stage 2 cams w/springs, HPS intake, 75MM throttle body/plenum combo, Long tube headers, 7qt oil pan.
Let me know what you all think. Is this a good engine to start with? Should I do these mods? Let me know what you guys think. |

I'm still kicking around the idea and building the bottom end but It can be the budget breaker. I'm hoping to keep the budget around 5000 or 6000. That includes the price of the motor.

The motor will cost $1900 and I have not bought it yet. I'm only guessing with the HP will be. I'm sure it's going to more than 300hp. I have thought about keeping the crank that is in there and upgrading the pistons and rods.

The crank should be plenty strong it's rated for up to 600 I think ....replace the pistons and rods and you'll be a happy camper. You should have enough in you're budget to do this |
I could be wrong on this, but don't the explorer's have 31 spline axles? Anyway, you might want to see if you can get those from the explorer while your at it.

I just want to make this aluminum block is going to take the abuse and what should be upgraded and what I can leave the way it is. I would hate to buy this thing and find out it will not work for what I want it to do. |
You're buying the entire long block?
