Choosing a Head

[blykins]

The only head out of the ones that you mentioned that are for a big block are the SCJ heads, and comparatively speaking, they're nothing special.

Don't waste your money on a new block, just use a regular production block. They have plenty of room for stroker crankshafts and in stock form will hold 700-750hp. There's no need in spending thousands for a block when you can get one for $100.

As for the heads, the best bang for the buck are the Trick Flow Street heads for the 429/460. They flow about 350cfm right out of the box.

If you don't already have a stock rotating assembly (crank and rods) that you can use and you need to spend money on a new setup, just go ahead and spring for a stroker kit. The 4.300" kit is very popular and will net you around 520-530 cubic inches.

Getting 500-600hp out of a 460 is easy as pie, with just some good heads and a cam. When you start increasing stroke and displacement, you're adding the torque to go with it.

Now, you'll have to really quantify how much power you want, because when you say that you want the most power that you can get on pump gas, you're probably looking at 700-750hp.

Probably one of, if not the best set of heads you can buy.

Thanks for the input! It definitely helped. As far as how man ponies I want to cram into the 460, I was hoping for it to be ABLE to make at least 800HP. Granted not on pump gas but seeing as how I will be using one (or more) ECUs I will be able to set up profiles. One thing I was considering was actually a SLIGHTLY shorter stroke to maximize the top end HP. I will be using twin blowers (I actually prefer superchargers over turbos). Here is what I have so far. Any input is appreciated.

You're way overkill on everything, including horsepower. 800hp for a street car is just simply too dangerous IMO.

However, if you're set on that, I would invest in the block and the P51 heads, and skip the forced induction. You don't need it.

A longer stroke WILL NOT limit top end horsepower, but increases the horsepower along with the torque along the same curve, all while being able to use a milder camshaft compared to a smaller displacement.

A 4.5" bore with a 4.5" stroke will give you 573ci, and with that displacement, the right cam, and those heads, you'll get your 800hp and then some.

Don't take this the wrong way, but if you're planning on something like this, let a professional engine builder do it for you.

When you're listing a set of heads, and you're not sure if they fit a small block or a big block, building a 800hp race engine, may just be out of your realm of experience.

Have you ever driven anything with 800hp? 500hp?
