do the fuel injected 460 heads have the same intake pattern as the older 460 heads ?
put a stock 460 motor from a 1995 truck into my car for backet racing..the motor is fuel injected but i want to put a carb intake on it, just wanted to know ahead of time if the carb intake will fithow old ....is old....????
...WHAT are you trying to do....???
what does that have to do with stock head bolt pattern on A newer 4601995 460 heads are going to be fuelie heads. ... flowing E7 casting with 2.19" intake valve. Head has not been decked which will pick up 7 cfm at the higher lifts.
Flow rate for the casting alone.
.200" / 152
.300" / 215
.400" / 263
.500" / 296
.600" / 318
.700" / 331
.800" / 343
Flow rates for casting with intake attached and pad radius:
upper runner / lower runner / unported intake lower runner / converted victor #1 runner
.200" / 149 / 153 / 153 / 155
.300" / 196 / 203 / 190 / 218
.400" / 230 / 238 / 222 / 267
.500" / 251 / 261 / 240 / 298
.600" / 265 / 273 / 250 / 313
.700" / 271 / 283 / 255 / 327
.800" / 280 / 290 / 259 / 339
A standard edelbrock performer intake blows 270 cfm max on the short runner and 255 max on the corner runners. on a comparable dove head max flow rates attached are in the 240 to 255 range depending on corner and or upper and lower. Most bbf dual planes flow better on the lower runners when on the cylinder head casting.
The good runners on the stealth and or rpm flow 323 ish low runner and 300 high runner max on a comparable dove casting with large valves. The victor in in the 340's.
All and all I would venture to say that while the fuelie intake is a restriction it is not too bad for a factory intake and will support good torque & hp with a carb adapter or properly set up EFI...

The intake and exhaust bolt patterns are the same, meaning that technically the carbed intake and exhaust manfiold bolt holes align to the FI head bolt patters and visa versa,do the fuel injected 460 heads have the same intake pattern as the older 460 heads?
1987 is the last year of the carbed 460's. Are you sure it's a 1987? Because 1988 is FI. The 1988 and up 460's have the valve cover bolts in the center of the valve covers (FI), while the earlier 460's have them around the perimeter of the valve covers (carbed).i am build a nice bracket car...i got a killer deal on a complete 460 for a early 90's ford truck with a 460, but i want to put a carb on it...ok..found out, the motor is from a 1987 truck..
That won't work, but you can port the FI intake and install a carb adaptor from Price Motorsports, Part No. CS-460EFI:... a stock 460 motor from a 1995 truck into my car for backet racing..the motor is fuel injected but i want to put a carb intake on it, just wanted to know ahead of time if the carb intake will fit
Will the 1970 BLOCK work with all the engine parts from the the 1997 engine? Yes, meaning that the entire 1997 rotating assembly may be instlled into the 1970 block, and all the other parts that make up the shortblock (timing cover, timing chain, oil pump, etc.) are a direct fit, except that a few oil pan bolts F&R are different sizes....which is no biggie just go to your hardware store....will an 70 block work for a 97 block replacement?
This is a different question than the one above, and the answer gets tricky. Will the 1997 heads and intake and all accessory brackets fit the 1970-era shortblock? Well, the 1997 top end will bolt to the 1970 shortblock, BUT the 1970 engine is internally balanced, while the 1997 engine is externally balanced. Therefore, you must have a COMPLETE 1970 shortblock, because your 1997 external balance flexplate/flywheel/crankshaft spacer will not work correctly with the 1970 internally balanced crankshaft which uses a zero-balanced flexplate/flywheel/crankshaft spacer. (You may run either an internal balanced engine or external balanced engine in your F250, etc, but you cannot mix parts between the two rotating assemblies.)can i use the 97 heads and intake and brackets on the 70 block?
at this time and on this build i am not goin to spend a lot of $$$ again on a car, i want to bracket race , even in both trophy 1 and 2 there is a et break , i pretty much got a good running 460-tranny and parts for next to nothing to put in a old junker i have..83 4door mercury zephyr..14.00 or faster or slower i diont care, it has at least run a 25.00 or so ..lol..i alrerdy have a tach..all ectronics..carb..etc..when its done i will have less then 1000.00 in the whiole car, will it be a 12 sec car..seriouly dont think so, it will not look as clean and good as my 84 stang did, i am bracket racing ..thanks..just as your own sig says...
you may spend a lifetime...." screwing around with poor setup parts..." ...just to see if you can make a difference..
for someone like you, you are just wasting time....
you should use the block and such,....but install a tried and proven set of heads and common regular carby type intake manifold.....
beyond some few basic additional power changes,..
you will be restricted to just a few additions, and still have the basic airflow restriction...
and then when you want more power than that, everything else will have to be changed anyways...
why dont you just change it first so that you do not have to buy all again....
what am i doing wrong ? the head are not coming off, i am buigna adapter to run a carb on it with the intake that is already on it..the bolt locations may be the same...but the port sealing issues are just as a 2 barell cleveland head as compared to a 4 Barrell cleveland head.....
ports do not seal properly....
early traditional 429/460 head as compared to a late 460 injected head... ......SAME DEAL....
you have spent the time to ask the RIGHT people,
you have the correct answers,
so there is no readson to do a hack job and do it WRONG....
The issue, if there is one, is that the E7 head doesn't work that great unless you port the bejesus out of it. Only after you port it is it then comparable to the old D0VE 429 head in terms of port flow....it's not a bad head, so to speak.what am i doing wrong ? the head are not coming off, i am buigna adapter to run a carb on it with the intake that is already on it..
