Im doing some changes on my tiger, for sale is the upper and lower manifolds w asm monoblade throttle body with marren 55 lb high impedence injectors. With the proper engine and comp setup these are putting out 645 hp and 670 lbs of tq. I am keeping the comp and wiring. These are in perfect shape and currently running on my boat. 2250.00 each or best offer.... 410 746 0020 or rob(at)proformauto.com

What are the flame arrestors?

the arrestors are from Cigarette and will be for sale separately. K&N does make a filter specifically for these throttle bodys.

Is there any corrosion on the lowers?

No corrosion, the lower manifold on the 500 efi has a brass insert that the 525 doesnt have. My blocks are 509 ci... others are selling just the manifolds and stock throttle bodys for 2k. Im including bigger injectors and bigger throttle bodies. Email me an offer, engines are coming out next week and will be available for shipping of pick up.

Will you sell the cool fuel and all the fuel lines with them?

No, i need them for my new setup.You cant use a stock fuel pump or merc fuel lines for this hp, it will lean out and kaboom. I use aeromotive A1000 pump and filter as well as fuel seperator. You should also upgrade to 8an or 10an lines. Ill include pics of how i have the fuel lines run to the purchaser. My return line goes back to the seperator/filter.

what heads are you running on these motors

Afr 335

So your detuning your engines and going back to stock cool fuel,
