where do I start?

[jaymegriffiths]

Dave has a Roush 427R?

It's a secret, don't let the beast out!

One hell of a car to drive in good weather! Worked all my life to get one like this, do the same.
Dave

WOW I drooled quite a bit. Good work, hopefully one day I'll have worked long and hard enough to earn a car like that! I hate it when you see 18year olds who get daddy to buy them a corvette or a sweet new stang. I wanna earn my sweet new car so i can show it off. looks awesome way to choose ford man!

 

[jaymegriffiths]

ok! I gotta good start! I found a C6 in an 82 f150.(SGI total loss asking 300 at the salvage yard) I dont know if its a 2 or 4 barrel but my dad said its possible it could be a 4 barrel carb(very well may be a holley, which is what he recommended!) which would kill 2 birds in one stone, and i could sell the truck and make some of it back! gonna go check it tomorrow. Could someone provide me with a list of vehicles equipped with a roller 5.0L and how to identify these engines. I realize that some vehicles it varies case by case, but if necessary i can havbe my dad come look and see. I've read some sutff on google but it says roller 5.0's were available as early as 85 but my dad argues they werent made til 90 or 91! could someone clear this up for me?

I think all of the cars from '85' and newer had roller cams. Even the trucks were able to use the roller cam but did not come with them. Roller cam does not mean they had the HO. The '85' Crown Vic and Grand Marquis were both roller camed but only had 150HP. If your going to rebuild, don't worry too much about the internals.

All the 5.0's had roller blocks starting in 1986. Pickups and vans got roller cams in 1992 and later got a cam upgrade in 1994. This cam was later used in the 1996-2001 Explorer/Mountaineer 5.0. It's just a shade less cam than the HO grind. The Crown Vic/Marquis/Town car 5.0 had crappy heads and small roller cams from 1986-1991, this same cam was used in the 1992-93 pickup/van 5.0. The 1986-90 T-Bird/Cougar also had the crappy heads/small cam as the big cars.

OK. since the heads are being replaced with afr ones, and roller rockers installed, that doesn't matter, and the camp with one with significantly more lift, the only thing i really need to do is worry about the block being built to support the roller rockers pushrods guides. i read there is kits designed to put a roller cam and the guides in a non roller I've also read that the pushrods can stay stock with my new heads. If Anything im saying is incorrect please let me know. dont want no "misinformation"

As long as the pistons have valve reliefs, it makes no difference what block you use came from.(The CV/Marquis/Lincoln 5.0's had no reliefs in the pistons) As for retrofitting a roller cam in a non roller block, that's an expensive proposition, total cost runs up to the 600-700 dollar range for everything needed.

Well i am planning on rebuilding and have been researching the option of a 331 stroker. Originally I planned to do a 347 but I've been told the short pistons cause issues and make the 347 a weak engine for high horsepower and reliability. Also I think this confirms that as i dont have an engine to build right now it would be more cost effective to rebuild a roller then to pay 6 or 700 bucks to convert. Seeing as i havent got a base to work with yet It leaves options as to what I do, and I'm takin the time to figure out the best, most reliable and durable engine, and I wanna make as much HP as I can with a little less than rediculous budget. It's nice knowing you have no time restriction, so I can just do the upgrades i want and take my time to find the good deals!


If i put the AFR heads, roller everything, and 331 stroker kit, Is nitrous an option for the track? can i have the intake ported, ar do I have to buy a nitrous ported intake? and when running nitrous, will the 4 barrel holley 600 found from factory work as a suitable carb or Is a carb am important choice when trying to run nitrous?

 

[Mac]

Be careful about your wishes. A over bored 302 (306) with the 165 AFR heads and even a mild cam will give you close to 380 HP. Above that, just start thowing money at the project, better trans, better cooling, rear end, better induction. Make your needs to match your wallet.

I was not trying to tell you what to do,it was just an example of what i did(and iam sorry for hijacking your thread a little....lol).Do what you want.....if you want a blown 300 six..i say go for it!
But look what your saying now.....you want to stroke a 302 to 347......what for..... more torque and Hp.
In a backasswards kinda way i was trying to help,didnt mean to come of as trying to bend you to my way of thinking (gezzzzz i wouldnt wish that on someone i didnt like) so i hope we can start over.

Dave......................you stink.............but your my new hero!
(just kidding about the stink comment)
Didnt the 427 in your Mustang start with a 351W block?

Big mis-conception about the 427. That's the hp rating, it's still a 4.6L. Just shoot me a PM instead of us starting something in the middle of something else!

My point was he went from 302 to stroking to get more cubic inches.In my first post I said if I knew then what i know now i would have went 351 instead of 302,that would be the same for 4X4 or 2 wheel drive.

But your right........I got side tracked again....lol.

your totally right. I am so indecicive its sad. but I havent really committed to anything. can you honestly say youd rather have a 351 than a 347 stroker? heck id take the stroker simply for uniqueness anyday.
I am having a very hard time finding a roller 5.0 so I may use a non roller. flat tappets aren't to bad and the 700 ill save on not buyin a roller conversion will easily make up the horsepower losses and most likely create a nice gain. for 3000 i can build a hell of a 302, and my dad said if i get the block line bored and decked, buy a balanced forged steel crank, and higher compression i can make 450 horse pretty quick. He's gonna help me build it, and he said the combo i was lookin at would cost upward of 5 grand and make well over 600 horse. he also said nitrous is a costly upgrade which is useless in my case as it wouldn't be good to use on the street and my truck will see little to no track time. plus then i can run aluminum pistons. A decent cam on top of that and I'm set! plenty of power for a 3500 pound truck and build reliable enough to drive every day. if anyone wants to point out obvious problems with this please feel free, as Im trusting my dads knowledge on ford v8's he's built many of them(including his 1970 mach 1 351 cleveland making over 700 RWHP!!! had a 9500 rpm rev limmiter that it staged at when dragging. wow!)

wow. yup, definitly assumed 427 CI. at least im not a lone idiot haha

 

[COPPERHEAD85]

you're never the lone idiot when I'm around.......lol.
You can take a 351 to 427 cubic inches.
I would deff. listen to your dad.......sounds like he has it down pat!(plus the cool factor of a build with your dad)

 

[Mac]

I think the limiting factor in a 351 built for power (not off road torque) would be the lack of good headers. Any out there, seems like no one has found a good one from what I remember.
