Hmmm....Only have a few:

1.) Honda CBR600 DOHC, 16 Valve, Inline 4.... It'* an indestructable aluminium wonder.
2.) Chevrolet 90degree Small Block V8.... For an obsolete pushrod engine, it has to be the most easily understood and widely used motor on the planet.
3.) Mazda/Wankel Rotory... An idea that should be used more often.
4.) Volkswagon/Porsche Air Cooled Flat 4... Another great power-to-weight marvel
5.) Pratt & Whitney Wasp Major... 28 cylinders, 4360cid, Supercharger, 4000+ bhp. It just doesn't get any bigger...if only I had a vehicle to use one on.

Heh, that engine weights as much as a SSEi

1) Series II 3800 (reliability and ease of mods)
2) Small Block Chevy (pre-92) (just purely because for a 50 year old design its not bad, widely used, easy to find parts, SIMPLE)
3) '89-'90 Chevy Turbo 3.1 (only because of the coolness factor and I've never really had a problem with mine)
4) Supercharged Ecotecs (lots of power for the engine size, bulletproof bottom end)
5) LS Series (ease of mods and just because who can argue that an LS7 isn't badass)
6) H.O. and W41 Quad 4'* (180 & 190 hp in '90 & '91 from an N/A 2.3 from Oldsmobile, impressive in my book and personally I never had the reliability problems that they supposedly have)
7) Rotarys (any of the ones before the current renesis (SP?), because of the idea, the only downfall is needing to be rebuilt often)
8) Ford 302 (only because of how widespread their use is and how they ALWAYS sound good)
9) Chrysler 2.2/2.5 Turbos (not the most reliable things but they're easy to make go fast and are pretty cheap to find nowadays)
10) Prolly my 5.5hp Honda small engine. These things take tons of abuse, work awesome in go-karts and pushmowers....

1)Mitsubishi 4g37 (1.8l SOHC) Lack of HP, but completely bullet-proof
2)GM 3.8l SII n/a and */c Weak trans. otherwise solid.
3)Any GM LSx motor Brute power....
4)Hyundai 2.7l DOHC V-6 (Tiburon GT'*) Handle more than many people would think
5)GM 2.2l (Cavalier/Sunfire) More grunt than you would expect
6)Chrysler 3.0
7)Ford 4.6l DOHC V-8 (Have a great sound to them)
The infamous 3.4l DOHC........ Just kidding.

i agreer with the 7.3 i put 128,000 on one in 9 months no prob and the cummins is a 5.9 in the dodge i have a 01.5 with the VP44 injection system and i love it and don't leave out the Wankel they are great for power to weight ratio of the block

10...GM 60 degree V6'* (3100, 3.4 DOHC, 3900vvt etc)
9...Pontiac 455 V8
8...Ford 5.4L V8 (supercharged and non-sc)
7...4.4L/4.6L Northstar V8
6...GM LSJ 2.0 Supercharged I4
5...2.3/2.4 Quad4'*
4...any Chevy SB 350
3...LS Series (LS1, LS2, LS7 etc)
2...3800 series II V6
1...3.8L Turbo V6

Gee Im kinda one sided huh?

Why this? The Turbo'd 2.0 has soooo much more powerl, and more potential..

Well isnt the turbo engine still an LSJ? Turbo/SC doesnt matter, still a great little engine.
