Some aftermarket EFI systems can handle power adders but some cannot. Do your homework and outline a build plan!

 

Fitech make a 600hp and a 1200hp power adder system and a 2x4 power adder
BTW I'm shooting for 600hp+ forgot to say that before and by special I was meaning the milled .026 part

 

If you are going EFI then I would look at a Novi or Paxton for a supercharger as Hio mentioned. Good throttle response without the lag of a turbo and with a FE the torque on the bottom will be fun.


The FE will not turn enough R's for a big turbo so you will be limited on size.


If your doing a crank and rods, I would go with a stroke crank and push it to 447 since your 0.40 over. As it was mentioned before you will need the top end worked over as well as the stock FE rockers and guides will not like what your doing. I would suggest rollers since we are going this far.


Now the down side. You will have way more money in this FE when you could have built a big cube 385 family block and hit you 600 without a power adder. However, you have a FE so make it a good one.

How much boost can I throw at a stock crank

 

I think 600+hp on a boosted FE will be very expensive, and extremely cool. The FE will require more boost to get to 600hp compared to a more efficient flowing engine. 600hp might take 20+psi

The boost the engine will tolerate will also depend in CR and fuel type. To get 600hp you will likely need more boost than 91/93 octane fuel can support, even with a low CR.
Can you get E85 in your area? If so you can run higher CR and more timing and achieve more power. You'll need the 1200hp fuel system to do it. Roots/Centri/turbo will all have the same issue.

I would run a single intelligently-sized turbo with a boost controller. If your pockets are deep a twin screw (whipple/KB) with a custom manifold would be cool too.

 

I think I'm gonna build a 460 for boost and then put a put either TT or a supercharger. Maybe not. Might just stick with what I have and go nitrous.

If you go nitrous, piston ring gap will have to be increased (from stock).

 

Sounds like you are aiming high. But here is one thing to consider. Stroke your existing 302. A stroker crank with a 3.4" stroke,special pistons, and .030 over cylinders can net you 347 CID. FRPP ( Ford Racing Performance Parts) used to carry a stroker kit to do this. It was part number M6013B347. With a SBF the choices for a transmission behind it are endless.

 

I have read through your posts.
Do a lot of homework and report back.
Or do as you propose and report back. We are all here to learn.

 

A 347 stroker is as big as you can go with a 302/5.0L engine and many people that look to stroke their 302/5.0L engine pick the 347 for no other reason than the cubic inch number they see, without checking into anything else about the pros an cons of it.

Years ago, when I was kicking around the idea to someday stroke a 5.0L engine for my '68 Mustang, I did a lot of research on this subject. The conclusion I came to was a 331 stroker, while a little smaller than the 347, is a much better choice between the two.

If staying within the SBF engine family, the 351W gives an immediate 49 cubic inch advantage, in unmodified form, over the 302/5.0L engine. There are all sorts of stroker kits available for a 351W --363, 383, 408, 427 strokers to name a few of the more popular ones. If you really wanted to spend some money, you could get a Ford Racing siamese bore block that can be punched out and stroked to a whopping 454 cubic inches. Big-block power without the big-block weight penalty or physical outward size.

Higher RPM capability equals higher exhaust velocity that would easily drive a turbo. It just all depends on what a person wants and how many cubic dollars they're willing to spend on parts in meeting their objective, whatever engine/engine family they ultimately decide to go with.

And a small block will spool up quicker than a FE.
