Acceptable Miles on Engine for Boost

How many miles on an engine would everyone consider being too high to install a Vortech on?

Assume a properly maintained, not abused, 4.6L DOHC engine and a standard boost Vortech setup.

Obviously a leak down test would be best so you know what the cylinder sealing is like, but as a ballpark what does everyone consider ok? No more than 50K, 100K, 150K, 200K, 300K, 500K….

97 Lincoln Mark VIII LSC (Chip'd, 3.73 T/L... so far... )
97 Ford Aspire (Slow, but getting 36 mpg (f'n Ethenol!! )
84 F250 Dually w/6.9L Diesel (7.3L IDI pending)
73 Mercury Cougar Convertible w/351C 4V (Partially Restored)
69 F100 LWB w/460 Engine
76 Glastron Carlson 23' Jet Boat w/460 CJ Engine

Just do it, man. If it blows up that will be a good excuse to rebuild it.

it's not like you don't have anything else to drive while you're doing the Mark rebuild.

Sometimes, we just need to remember what the rules of life really are:
You only need two tools: WD-40 and Duct Tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Personally, I would probably be a little worried with over 200K on it. Of course other things come into play too, such as how well the car was maintained and how much of its history you know.

Really what it comes down to though isn't a question of mileage, its a question of whether you can afford to blow the motor. With the vortech and a stock bottom end, it could blow at any mileage, so if that's going to be a big problem for you, then don't do it. But if you can afford to park the car for a while while you save up the money to rebuild the motor, then go ahead and do it. If the motor grenades, its just an excuse for a forged bottom end.

-91 Cougar LS, coming soon, complete overhaul with a 427" Windsor.

-98 Mark VIII LSC, Procharger P600b, TR3650 swap and 3.73s.
