400 HP Indmar Raptor!

^ I would have lost that bet...I would have figured an over/under of about 15 minutes at 2500 rpm.

Should give it to my wife to drive. Ours was making all kinds of funky noises when we go rid of it at 80k. Pretty sure there were issues in the valve train inclusive of the cam timing units.

Most engines today have great bottom ends, it's all the specialty things they throw on them that seems to fail.

We once tried to kill a triton 5.4l also.....but in a truck. Long story as to why, but here's the short end.

We drained all the coolant .......and oil. Let it run at idle and it went FOUR FREAKIN HOURS.....still running. Decided to ramp up the rpm to 2500 or so... It ran for about 2 more hours before it finally stopped. Pulled her out and tore her down to see what failed and the only real noticeable damage was scored cam journals, the right side cam finally seized and cause it to stop running. The main and rod bearings still looked extremely good, only slight signs of over heating .

The bottom end on the triton modular series is very stout. 6.2 is the same basic design.

If it had been treated with duralube it would still be running! (or was it slick 50?)....I remember those ads where they ran engines with no oil and dumped eevrything they could on cams and valves like sand. Was pretty amazing.

Thats good to hear.

In the big picture my little side jobs don't amount to very much volume......and yet I have replaced several toyota engines/ heads due to oil starvation (sludge)

Coincidence or trend I dunno.

Real exciting audience. ha

Its a Toyota.....People think they don't have to take care of them and they run forever .

does one brand of engine produce more sludge than another? Or is it just that the oil galleys/channels (whatever they are called?) are tighter and more prone to gum up? Is this something that a can of seafoam in the oil every 60k or so would prevent? What was the oil change history?

I'm trying to wean myself from the 1960s "every 3000 miles" advice on oil changes. Still can't bear to go past 5000 miles, and even then my civic's little computer tells me that there's 40% oil life remaining.

This reminds me of an ongoing question I have about oil change intervals. But it's not relevant to this topic, so I'll raise it on the Off Topic forum. Hoping to get Bobby's input on this one specifically. I know there are also others knowledgeable on the subject...

I haven't tried to confirm this but the theory I have is inadequate PCV systems (toyota). I also remember reading a TSB for dodge 4.7s about inadequate PCV and sludge. BICBW

Here is one source that agrees http://www.toyoland.com/sludge.html

Indmar web page has been updated with details on the Ford engines. The numbers on the engines are based on torque not horsepower.

The 5 year warranty is nice, not 3rd party.

Definitely a bonus to have I would think, especially since it's a new motor that hasn't proven itself like the 350.
