There is a local gentleman selling a 1981 F250 with a built 429 police interceptor. He has dyno sheets to prove and is putting out a little over 550hp. It has fox body mustang 6quart oil pan, fox body headers, and basically the kit to bolt into a fox body mustang. He has it hooked up to a c6 with 1500 stall. these are specs he posted as well now...

"this motor is race ready all kinds of goodies 850cfm edelbrock carb, edelbrock performer intake, dove heads, electronic ignition, big tube hooker competion headers 3inch dual exhaust with flowmasters, high volume oil pump, 6qtoil pan, roller rocker arms,guide plates, hardened pushrods, flat top one valve relief pistons, .579lift cam, ford racing valve covers, c6 transmission with 1500 stall dana 60 rearend with 3:73 gears, have 3000 stall convertor 750 holley double pumper manual trans and a unused set of headers i will include for asking price"

Now with that said he is asking $3600... Is this price reasonable for all the extras? The biggest thing i would rather have would be the manual tranny but he does not have bell housing. Other than that is this worth the money? It drives FLAWLESSLY!!!! Puts you back in your seat all through the gears and hits max speed on speedo without breaking a sweat and keeps pulling well into 100mph guaranteed from my personal experience with these trucks.


So the basic question is, Is it worth the money???? i would buy it for the motor and drivetrain and rear and prob junk the body to a scrap yard for a couple hundred to invest in the swap.

 

Thats a lot of money for a used drivetrain and it's just a 429. I don't know why someone would go to all the trouble of building a big block, then stick a 429 crank in it when 460 cranks are a dime a dozen. I wouldn't care about his dyno sheet, those numbers sound inflated to me with the build described. Now if the body was nice then maybe 3k. You could sell it off. Good beds always sell and if the paint is nice someone might buy all of it to put on a 4x4 frame.

 

Even if those numbers are inflated, the motor truck halls a** for a 81 3/4 ton. I have never been in a truck that size that is that quick unless its a rumble bee or a diesel with some descent mods. Body is very good shape… Still debating though. Was thinking of doing a stroked 460 and buying just a block from local yard and building it up. Could be cheaper and get more power for the money.

 

That cam isn't enough to make 550HP in a 429,even if the DOVE heads are fully ported by the MAD PORTER.Those numbers are inflated.If the truck is in good condition overall with a good running bigblock,let your wallet guide you.Are you looking for a truck or a powertrain?I'm always suspicious of people who advertise a vehicle with misleading/questionable claims.Makes me wonder if there is something they're hiding.If it's a fast truck you want and you're happy with the way it runs/rides then make sure you go over it thoroughly.I drive the crap out of my vehicles,but I know how to maintain/repair them.I always try to buy stock or original condition vehicles and modify them myself.That way I know whats done to them.I hate having someone else work on any vehicle I own.

 

All is taken care of. Just bought a 1995 Ford lightning.. Alot faster and alot more pleased as it can street race a little better . Iunderstand where you come from though. This is stock besides drop shackles and front lowering springs along with an intake. So nothing major. Had tranny professionally rebuilt with receipts and warranty so i am pleased.

 

First off he is lying to you. It's not a PI 429 it's just a plain jane 429 might have even been a 2bbl grandma car motor. There is nothing and I mean absolutely NOTHING special about D0VE heads. They are the stock heads used on stock motors in 1970 and 1971. They are the base model heads that even Ford thought weren't good enough for even the mild performance engines.

The only "official" PI heads used on 429s would have a D2OE casting number on them.

As to the rest, sounds like a stock build with a bunch of mismatched parts that would be lucky to make the factory original 365hp honestly. Guy didn't know what he was building. 3" headers are WAY to big for a pretty much stock motor (.579 lift ain't that much, and lift don't tell squat on a cam anyway)

and then to stick a performer intake against those headers and that cam (if it's any type of cam at all it needs more then an alum version of the stock intake)

Now I know you bought something else, just adding in case someone else does a search on police interceptors. You made the right choice buying ANYTHING else, that motor was not done by a competent builder trust me.

 

Does it have an 850 edelbrock or a 750 holley dp ?
