Thread: 429 info

Tweet

bought a 1965 f-100 with a 429 in it, previous owner did not know much about the engine, said it was a 1975 year model, intake has d6ve-9425-a3a and heads have d3ve-a2a, it has a holly 4150 carb, i cannot find the number for the engine, i looked at the back side where can that be found, looking to put alum intake, headers, and eventually a mild cam, anyone have suggestions or more info about this engine ?,, seen a good few tips allready,

D6VE is a 1976 intake. D3VE heads are 1973 (or newer).
429's and 460's seemed to have really mild stock cams. Any aftermarket cam is an improvement.

Not sure, but I believe that is one of the years that had the retarded chain and gears on it. A new cam and timing set would do wonders for it....

Ford 429's were not produced in 1975 and I believe 1973 was the last year. Hopefully it's a 1975 460.

If it is a 460, then the pre-72 straight up timing chain is the way to go (available in aftermarket). If it is a 1973 429, then not only is the chain a good way to go but so is a pair of D0VE heads...OR a piston change. The compression ratio of the 1973 429 is dismal, like 7.6:1. Flat top pistons or D0VE heads will bring the c/r somewhat closer to 9:1.

A good mild cam that will work with a bone stock 429/460 might be the Summit grind SUM-3501...but again if you ahve the 7.6:1 c/r motor, you must address the c/r issue first.

where can i find the engine code, i looked at the back of the engine but due to the way the engine is in there cant really see much,want to find out what is there to set timing and see which way im going to procced

also, what should the timing be set at?,, and with the vacuum advance hooked up or off ?

Posted by Paul Kane on another forum...
"The block casting number is located on the side of the block, down low, behind the starter motor and reads vertically."

Find out what you have first, then address timing and such.

my neighbor was a car salesman at a dealership in the early 70s, they had a mustang boss 429 that sat on the lot for two years, he tried and tried to sell the car, still brand new mind you, and finally did for $2000.... the 429 was never the best motor out there, the 460s were a better setup........

cant see the number, its too tight, between the exhaust manifold, starter and frame i cant get up in there to see much going to have to get a mirror or something, all i could see was like an a3 or something,

I'll keep it simple,, what is better about a 460 than a 429? Except for a longer
cast iron crank. If your friend could not sell a Boss 429 it's because nobody
knew what it was!

Pull the starter.

the 429s, especially the california equipment cars, were very choked motors, and didn't perform well at all, especially as for the cost compared to other motors offered the same years.... the only 429s i've personally come across are california smog equipped motors.... i'm sure with enough money dumped into them the 429s can be a great motor, as can any motor be great depending on how much money you put in it

ok, this is what i have

block D1VE A2B
heads D3VE A2A
intake D6VE 9425 A3A
water pump D2VE BA

so what do i have here ? a 429 1971 block,1973 heads,1976 intake and 1972 water pump ?

thats exactly what you have... good guess

and it came out out of a lincon,,, so what should timing be,, and this is my plans for engine performance,,

DOVE c heads
headman full leangth headers
Edelbrock performer rpm intake
Edelbrock performer RPM cam & lifters
True-Roller timing chain set

havent decided on a HEI Distributor or not

open for suggestions,and comments,

thanks guys
