Right.. so with that reality check your next question is.. "so how much HP can I make within budget?" 300hp isn't that hard or expensive, maybe a little more with GT40 heads or some home porting on the stock E7s. Rebuild the bottom end to stock spec with 0.030" over pistons, get the heads ready, install the Comp 35-349-8(like a HO cam with more lift, and yes it's SD friendly), bolt on headers and a complete exhaust system, and there you go. I'd also suggest installing 4.10 gears in the rear axle and some traction bars, and a shift kit in the trans and then you're all set to go rice hunting.

I like your thinking. Not too extreme but enough.

Also he's keeping in mind two important parts: reliability and long run affordability (little to none extra maintenance and a chance you mileage will actually go up a little).

You don't need the 351 computer, just "Cross-wire" the injectors, and they use the same plug for the distributors. Thats what I did. I had a 5.0 in a 89, and I put in a 351 and kept the same computer.

Also from what research I have done. You can take a SD 351w, add good heads, headers, intake, throttle body, and larger injectors and get +-330hp, without even camming it up, or boring it out.

You messed up then, the injectors are batch fired and should not be altered at all, the only thing that has to change is the spark plug wiring order.

Sorry but.. larger injectors will not cooperate with a stock SD computer, and if someone did all that and only got 330hp they wasted their money because you can get nearly 300hp without the heads, intake, TB, and injectors.

What do you mean "batch" fired?

Do you know the specific order? or what injectors are in each batch?. It would seem 5.0 or 5.8 wouldn't really matter if they fire in batches

My assumptions on that would be, the firing order....Go 1-4, then 5-8...Whatever the firing order is....
I assume that the firing order would be the same as the injector sequence....As it wouldn't make sense to squirt fuel on a non-firing piston....

Its supposed to evenly distribute fuel in the intake
Because of this, Why should it matter 5.0 or 5.8?
