I'm building a 1959 f100 and putting a 1987 RV 460 in it . I'm planning on going with a Holley Sniper EFI. What all should I change and what part should I get to replace the old with? The motor only has 34000 miles.
Interesting that 1986 Ford F53 motohomes are EFI. Thus the E5 cylinder heads were designed in 1985 for 1986 production. So Ford didn't go EFI in the other models until later? I'm talking about the chassis model year, not the coach model year.EFI 460 came about end of 87 for the 88 model year. Can't say I've ever seen an 87 EFI 460.
If your RV engine is carbureted as it likely is:
A straight up double roller timing set, properly curved distributor and dual exhaust with headers will get you closer to 300 hp.
Static c/r is less than 8 to 1 on the carbed engines.
A performer intake is a good choice up to 1 hp per cubic inch. After that the RPM.
You will find the cylinder head casting numbers under the intake ports. E5 or E6TE would be typical. Not really any different functionally from D3's excepting accessory hole sizes.
We've had some low mileage RV engines come in beat to hell and worn out at 50k.
This is less common with the EFI engines.
Best to open up, check for issues and address them before install.

Yes Mad porter. It is a carbed motor should I change the heads or get a different cam or anything like that??

|Ford introduced the F53 chassis in 1988 with port injection. So if it's a Ford F53 chassis, it's EFI. There were some Oshkosh chassis with carbureted 460 Ford engines into the early 90s. Just open the dog house and have a look see.|
If you hear a "tic-tic" when you first start the engine, it probably has manifold problems.
