To make 700Hp the easy way use a big block typically 552CID

Ford Windsor heads Intake flows @.500 lift...

Stock 302 160CFM

GT40 185CFM

GT40P 190CFM

N351 232CFM

AFR 185 285CFM

I either use the N351 iron heads on lower cost builds, I port them a little and they make good torque.

Or we step up the AFR heads to make the most power.

I have made 575Hp Clevelands using Trickflow 195cc heads.

I've seen others make 620Hp with TFS 225 heads, which seems a bit disappointing but probably realistic.

I've made 700Hp at 6400rpm using Yates C3 heads and the D4 heads are even better.

800Hp will take over 7000rpm.

As we all know used Ford Cleveland blocks are getting harder to find and making over 600Hp is just asking to crack a cylinder or two.

Damper Length Ford dampers come in three lengths—the distance measured from the front face of the damper to the back of the hub.

They are approximately 3”, .35" (~3-3/8") or 4”.

Ford pulleys come in two bolt styles - either 3-bolt or 4-bolt fronts.

3-bolt pulleys are found on dampers with a length of 3"

4-bolt pulleys are used on 4" dampers, and 3.35" (~3-3/8") dampers use both 3 and 4 bolt fronts

This is my Ford information page. 

You will notice my website is different from every other engine builders site like Proformance Unlimited ATK Blueprint Engine Factory etc, that is because I don't sell engines, I build them.

In other words, I don't try to talk you into buying anything.

You tell me what you are thinking about building and I'll help you get it.

The builders above have combinations ready to go, I can't build motors as quickly as they can.

I can build them for less and I do build more powerful engines.

Most guys who buy motors from me want some more special.

Write to me and tell me what you are looking for

That said the cheapest 347 or 408 Windsor turnkey engine I build is $7200.

You can get one from another shop for $6900, so if you are shopping price I'm sure you will find it.

I focus on building more powerful combinations.

I build more Ford engines than Chevrolet engines
