Wesman's engine kaput overheated

Aluminum Cobra blocks are good for over 1000hp and are powering cars down the 1/4 mile in 6 seconds.

Ford wanted extra insurance as far as warrantys go for the 03/04 Cobra and models after... so they went with iron.

IMO... putting Aluminum heads on an iron block is more of an overheat hazard than have two like metals heat up and expand with eachother.

When I see an aluminum block blow to bits with 500hp I will start to condsider Iron.

A bunch of us have done this... I've done it twice. It's mostly due to the internal parts (powdered metal rods and hypereutectic pistons) rather than the block. But if you buy a factory rebuild that's the parts they use. Cast iron Cobra factory rebuilds have better internal parts because that's what they were originally built with.

Any car that can run 6 second is not a street driven car. Race motors are replace several times in a season. Sometimes pistons, rod, and values are replaced on the same event. I think what we are talking about is a street driven car with light track duty. Reliability and safety is the goal most Marauder owners want in their car. The chooses for a reasonable power solutions is limited to your personal budget. Very few of us will ever swap out an engine regardless of material used in the manufacturing process.

At this point i don't want 1000hp or 500hp, i just want it back on the road. Then i have to decide whether to keep it or not, before gas goes back up again.
 
Sorry to hear about your motor, hopefully you can get the Marauder out at Mosport later this year as I was really looking forward to meeting up at the track this summer, all the best in your search.
 
Hi Wes; sorry to here about your troubles.
I remember seeing somewhere a month ago a Marauder powertrain for sale, I'll try ang dig it up for you.

All the best,
Peter

Agreed. Why not just buy better internals and build them with your existing block... assuming the block isn't toast. If it was just an overheat I am sure the block is fine. Might need a deck re-surface.

Agreed... but people seem to think the aluminum block is a bad block for reliability. The block is more than capable. Engine needs to be built with quality internals. If I had the cash I would swap my rods/pistons with 03 Cobra rods/pistons and keep the block.
 
Got a stock engine for $1300, installed for $1200, plus new cats to pass etest and couple miscellaneous things, another $700. and battery died to top it all off.

Congrats Wes!
Glad to see that you are back in action...more track time now?
