Project 1995 EFI 300 in a 4WD F150, Short bed 3.55 gears. Planning mild cam and opening up the exhaust. I read that the factory EFI exhaust & intake manifold will breath just fine. Open the exhaust to 2.5 or 3 in and the rest should be just puting gas in and drive. Unless someone has a suggestion that will save me money . Everything I mention should come to under $1000. I guess when I'm done I will post how well it worked.

 

Awesome becuase I'm too close to deciding to replace mine with a 351...I'm getting horrible mileage and take pride in the fact that I put a bronco 2 in it's place on the highway...it's that bad lol. I need to see someone else succeed with this motor so I can believe in it again haha. It's the most durable lump of iron I've ever seen, but at this point i feel that's all it's got goin for it. I'm gonna go put it on my buddies dynojet just for grins, but it's just a shame I have to sneak in without the Honda kids finding out lol

Lots of info there about building up the 300. FWIW the giggest gains are going to be had from a minor porting of the head: opening up the bowls, 3-angle valve job, reducing the valve guide bosses and Thermactor bumps, blending the transitions, etc

 

MAP or MAF?

 

I am pretty sure I found the best place to get the performance parts , clifford performance .net their out of So Cal so don't talk va lot about removing your cats they get really jelous . The guy I talked to told me shave the head 0 deck the block intsall 194 valves . 474 lift cam headers withj 2.25 true duals , all this will get it done for under $1000 if you can do the wrench work yourself you can get your parts from www.cliffordperformance.net or if you can find someone at Autozone who really knows what they are doing you can order it from them according to the guy in So Cal you end up 10-1 comp 360 ft lbs of torque and about 240 hp . Don't change you 300 six for a 351 you will regret it ,

 

Lets not forget the simple thing Its a truck not a car. We don't want to go 10 sec. in the qtr mile. What we want is to pull a house if you can figure out how to hook tlo it.LOL The 300 6 is a torque monster . done right it will out pull a 460 and any small block chevy . I ordered my header I'll see tomorrow if I can figure out hows to up load a pic they are really pretty ceramic too, long tube hooker

 

Hope u were wearing ur hip waders because that guy was shovelin such a line of bull****. see my sig, thats about 180 crank hp.

edit: i dont know where it went but here it is:
1993 F-150 XLT 4x4
- Modded 300/Built E4OD
- D44 SAS, 5" lift
- Bald 33"s, goin w/ 35"s
- Cervini's RamAir hood
- 3G swap
- Crane cam
- Hedmen headers, Moroso spiraflow muffler
- Crane coil, Taylor wires
- Ported intakes, 351 TB
- Alpine, Infinity sound and more

ported intakes and 351 throttle body are useless. dont do it.

 

Jack Clifford died years ago. The guy who runs the company now knows little to nothing. He's discontinued about 75% of the stuff that Jack developed and lies through his teeth about the remainder. There is almost nothing that you can buy from Clifford that can't be had cheaper and/or better from other sources.

 

I knew there was a reason I joined a forum I know I can get the cam kit from comp cams. Around $265 new cam lifters and timing set. I also found headers they are pricey but I think I can get the manager to price match. So cam kit and headers. I have read too many other places that the Ford ignition system is perfect and doesn't need to be changed is this ture, or should I stop dreaming about good thrttle response and lots of torque from this 300 and swap to a 302. I know what can be done with one of those.

 

You don't need to waste the money on headers. The stock exhaust manifolds on a 95 flow very, very well. Look at them, they are essentially cast iron shorty headers. Unless you intend to get into a very high performance buildup, long tubes will give you a very small gain for the $$ expended. Add to that the fact that the stock manifolds have far fewer sealing or maintenance issues and it's a simple choice.

 

thank you StrangerRanger. I had heard that before. Will the cam kit do anything other than waste money. I have changed cams in two of my other rides with great outcome. of course they are both chevy V8 engines. I have also heard the ford ignition system is great and I don't need MSD. There really should be a Myth Busters for this crap. LOL thanks for yalls help.

 

The cam will most definitely NOT be a waste of money but make sure you get one that is computer-friendly. I don't know if the CompCams unit you're looking at is or is not. Isky and Crower both offer computer-compatible cams (not to be confused with smog-legal, that's a whole other matter) and Crane used to. Now that Crane is back in business I suspect that they will again soon if they don't already offer one.

You really should check out some of the discussion on the subject of cams at www.fordsix.com

 

already read it. of course you seem well versed in this matter and you know as well as I do that cam size is the one question that everbody wants an answer for but noone seems to have one . I ordered one its a kit comes with new lifters and chain kit . I haven't ever heard about a cam being computer freindly , and smog or emmisions I'm overly concerned about . you didn't mention whether or not this would be worth while . I don't expect it to have the torque like my wifes vet , but I also don't need power at 90 mph either. I would like it to pull my toys down the road withhout problems though thanks for the advice

 

If it comes with a chain, it's the wrong cam. There is no chain on a 300. The cam on a 300 is gear driven and you have to replace the gears if you go to an aftermarket cam. The stock cam gear is phenolic and will not stand up to the load.

If you go to the manufacturers' web sites and read the cam descriptions they will tell you if their cams are compatible with a computer, most are not. Using one which is not can cause severe drivability problems.AFAIK there are no smog-legal aftermarket cams for the 300. It's not a high volume enough item for anyone to go through the certification process.

 

I called Comp Cams today they said that nothing they showed for the 300 listed as computer freindly, I got one of the tech guys there not sales. He looked to see the differance between OE and the one I ordere and adie from lift a duration there was one degree differance in lobe angle. the cam specs are .456 lift int/exh 265* duration and 110* lobe angle. according to the tech guy Factory is 111* lobe angle. and it didn't come with a chain. I guess the picture was a generic picture. the engine in the pic was a V8. You still haven't answered me...... Was it worth it... Are yiou happy with your perfomance and mileage or if you had it to do over would you swao a 302?
