2V to 4V

5407 Views 120 Replies 12 Participants Last post by  norcalam2
So I am not too sure about these motors. I know that 4v are better then 2v. im planning on doing a kb'd 4v. and i was wondering what it would take to turn my engine into a 4v? i know that i'll need new headers and kb replace the intake. and i'm gonna forge the bottom. rough estimate of power will be 700. at the most. maybe a little nitrous we'll see. I'm thinking 03-04 heads.

I'm just planning for the future.

it maybe listed, but you cannot get one, should have made it more clear, you cannot get an ic'd one(manifolds were cracking) so in my opinion it is not worth it
wITH THE NEW TRICKFLOW HEADS OUT ANDT HE PRICE AND WORK NEEDED TO DO A 4V SWAP IS IT REALLY WORTH IT?
absolutly
So then i can't go kb with b heads? so then i have to fork out more for the c's? And you say the block isn't much more? and more than free? since i have a block in my gt right now. i'd rather save a grand then spend one.
Maybe i should just fork out the cash and get mmr's 900 longblock?
Then Kb
then all the bits and peices to make it work.

you can't run an intercooled KB on B heads, but why be limited to 6 psi?

you can get a teksid block for around 2-300, heard of people getting the cobra iron blocks for around 100

i have a teksid im trying too get rid of?
lol shipping to saskatchewan, canada?
I bought 2 things an hour ago.

1. how to build max-performance 4.6l Ford Engines.

2. Zex kit.

So as of today i'm now using my playing money on building a 4v engine.

Just something to keep me from waisting my money on bolt ons ;) until i can drop in my future engine.

Best book ever.
highly recommended for anyone considering to build a 4.6 or 5.4 engine. it tells you everything! and even shows you what some parts are like and which ones are better.
^^ well we all know that even "I hope they serve beer in hell" is a better book than sean hyland's but ya good book no doubt.

+1 Those trick flows are outflowing 4v heads. I can't even imagine how sick a set of those heads that are ported by someone that knows what they are doing are like.

*drool*
Trickflows are outflowing 4v's?
160 pages, are you ****ing kidding me? This is gonna take me all morning...

I Think the intake is a bit more and exhaust is slightly less. But they are a direct swap and fix all the problems with the 2vs, i dunno if the 4vs suffer for sprak plug blow outs or not. They are definately worth taking a look at. Personally I love the look of a 4v engine the heads/vavle cover just look so much better, but is it worth all that time effort and money to swap them over?
For these trickflow heads, they come with four-bolt replaceable cam bearing journals, 1.840in/1.450 in valves, powdered metal valve guides, ductile iron valve seats, chromemoly retainers and die-forged locks, beehive valve springs, and Vinton fluoroelastomer valve seals. It says they accept OE cams, followers, lash adjusters and valve covers.


What else is there to a head ie are there other things that you'd have to get to get these heads on and going?
Are followers and lash adjusters re-usable?
How much hp can these heads take, I'm looking for 600 rwhp?
Are the valves Stainless?
Would it be worth it to get bronze valve guides or titanium retainers?

Also, it says they increase the compression to like 10:1 WTF that's not good if I want to boost it...

All the factory pieces work with these heads. As far as upgraded guides and retainers i cant say, but It was Trick Flows intent to make the direct replacements. And they come with two different combustion chambers configurations so you can get a lower compression. Also Trickflow is suppose to be makin a different versions for blowers.
Not to knock trickflow or anything but If there heads flow just as good or slightly better than a stock 4V doesnt sound all that spectacular. I could be wrong but Why spring all that dough to end up where the 3V's or 4V's are just starting. Not to mention the 3 and 4's are boost friendly. ???? Like mentioned above, what extra hardware is needed for the TF's
