Bulldog motors
 

This may be a stupid question, but I've seen motors listed that are 540 or 500 "bulldogs" What is a "bulldog" motor and what makes it unique?

Where could I go to find specs on a 500 bulldog?

I'm looking for all the info I can get, I need a "Bulldog for Dummies" education. Thanks!

540ci 500hp

:cool:

Last made in 2001 by Mercury Racing.....the HP500 Bulldog:

- 542 cubic inches of raw power (8.9L)
- Blueprinted engine components
- Cast alluminum exhaust system and stainless pipes standard
- Full throttle range: 4800-5200
- Bore: 4.44 inches (113 mm)
- Stroke: 4.38 inches (111mm)
- Compression: 8.6 : 1
- Ignition type: Thunderbolt V
- Fuel system: 800 CFM Holley
- Fuel requirements: 87 octane
- Weight: 1,217 pounds

You could build a better Bulldog using larger port, higher CR aluminum heads, roller cam, and a 1050 Holley.

Top Secret stuff now days...

Was there a downside to them??
 

I think they were pricey compared to the hp500.

I kindof like the name...

Well, looking at the HP vs cubic inches, it should be a relaible package that makes decent torque. I recall looking at them a while ago, and they were a highr cost than the HP 500 (502)

Heck, it looks like there's some decent parts in there.....should work well with a solid roller, blower, and new valve springs..but then you lose the reliability

Yep...Great package to throw forced induction on.
You had the option of 3A's or even 5'swith them.
My buddy has a 42 Tiger/BravoXR's with Bulldogs and threw some Mega 420's on top of them....gained like 10+ mph.

Before...

After...He didn't even do cams, just bolt on and go play!

you gotta like a guy with a sense of humor!!:D :D :cool:

You have to have one around here...;)


With **** like this going on.

When the 500 EFI's came out there was a waiting list for the new motors. Cigarette put a few bulldogs in boats that were waiting on 500 EFI's for the same price. Seems like the Bull dog motor with a nice EFI would be a great engine!

hey : dont tell anybody : I made BULLDOG stickers and put them on top of flame arrestors... :) :)

The Bulldog has a black intake and the 502/HP500 has a blue one.
So your busted anyway.
Dude, You better put that turkish waterbong down now...Your toasted :p
