I am looking at putting a 12valve into my humvee project that i have and need some advice. I have found quite a few engines with the rotary pump for sale and not many with the in-line. Can decent power be made with the rotary or should i hold out and keep looking for an in-line pump motor. I have found a couple of nice engines for around 1500.00-2000.00 that are all the rotary pump. Most of them have over 200 thousand on them. Should i worry about the mileage or using that pump? Not a great selection up here in Wa st.

Any advice would be great from the guys who know the engines as i am new to the 12valve and only know what i have read so far.

Thanks

Todd

If the engine wasn't abused, I wouldn't worry about 200+ thousand miles at all.

To get info on the rotary pumps do some reading in the 1st gen forum.

How much HP are you wanting? A VE pump can put out about 250 - 300 HP, the main thing you have to worry about is having a transmission that will hold up to the increased HP.

Thanks for the replies guys. The more information i get the better. I was thinking of having a 47rh built for my project. I have no room for a manual transmission.

like mentioned, it all depends on your power goals

The VE pump (rotary pump found in dodge apps) is more suited to a sub 300hp engine. their are other rotary pumps that were used on these also.

while the inline (depending on the pump model) can support ~400-500hp with very little work to the pump itself

If you use the VE pump engine you'll need the 2nd Gen adapter, starter, and flywheel for your 47RH.

I was just going to ask about that. Thanks again for the input. Im not looking for 500hp. I just want enough to have fun with and not get beat by a kid on a ten speed when i am going over the passes here in WA. Seems like most of the 5.9's i have found are in the mid west or east coast. The ones in WA everyone wants 4-5grand for them and i cant make that happen lol.

You can gain alot of power with the free mods. If your going to go with the 1st gen VE engine I can move you to the 1st gen section.
