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.

Hi
Low miles on an RV would be like high miles on a car. they go thru a lot.. pulling that heavy load.. One thing I'd change would be the timing set to a early 0* set. See what kind of oil pressure doe it runs? Check and see what heads it has on it.. maybe up date Cam and lifter as well..

good luck take care be safe

1987 460 was EFI with the straight up, double row timing chain. RV engines have a minimum amount of cold starts for the miles on the odometer. As we all know, cold starts are where an engine get its maximum amount of wear. At 34,000 miles, that engine should have a minimum amount of wear if it was maintained properly. My 95 RV 460 had 0.0015" of cylinder wall wear at 140,000 miles. All this with cheap Walmart Synthec engine oil. Your engine probably has the E3TE heads.

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.

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.

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

You have many options depending on budget and power output expectations.

Start with my suggestions.

If you want more you can go to small chamber heads and some cam, performer intake and roller rockers.

Outline what your expectations are here and we can guide from there.

I have E5TE and E6TE castings on my storage shelves. Carb heads.

E7TE are of course the EFI castings first year.

I also have E8TE castings that were carb heads motor home class A if memory serves.

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.

I've seen both but not any BB EFI until 88.
