ok i just bought a rebuilt 460 the guy says it cmoe out of an 1975 thunderbird i was wondering the output for it is the number on the intake says DOVE - 9425B and the heads say D3VE - A2A someone please let me know the output and what year it is
[updated:LAST EDITED ON 26-Apr-02 AT 05:45 PM (EST)]The source book I'm looking at says the 1975 460 has 8.0:1 compression,and has 218(net)horsepower@4,000rpm.the D3VE-A2A heads are listed as '72-'74 year cylinder heads.Combustion chamber volume is 91.4cc,the intake valves are 2.08",and the exhaust valves are 1.66".The only difference listed between the '72-'74 heads&the D4VE '75-'78 year heads is the '75-'78 heads' combustion chamber volume is 96.2cc.
ok you say the the heads are 72 74 i just found out that it is an 1973 what are the horse power and torgue specs for it because the 75 have 96.2cc and the 73 has 91.4 there should be a difference in output please tell and what it the compression ratio and are the valves bigger
If the 460 engine you have is a 1973 year engine,it must have originally come in a Lincoln.The 460 wasn't offered in the Thunderbird until 1974 model year.The 429 was the 1973 T-bird big-block.One of two things:either it came out of a '73 year Lincoln,or it was rebuilt,and stroked from 429 to 460cid.The 1973 heads have the same valve sizes:2.08"intake,1.66"exhaust as the later heads.A 1973 460 is listed as having the same compression ratio(8.0:1),and horsepower is listed at 219@4,400rpm.Torque is listed at 357 lbs./ft.@2,200rpm.Basically,the 460 engines found in '72-'78 cars had the same(or close to it)horsepower&torque ratings.In contrast,the 1973 429 was listed at 201 horsepower@4,400rpm.It also had 8.0:1 compression.Starting in 1972,Ford used net horsepower ratings for it's engines.
The D0VE part of your vin means that it is a 1970 model block. (the D stands for the the 1970-1979 decade like C stands for the 1960-1969 decade. The 0 stands for the year, 1970.) If it was out of a 1975 thunderbird the vin would be D5VE. The heads are from a 1973 model engine.
