which motor

[BiGwiLLswiLLy]

merlin or gm crate motor? with would you think is best a 502 gm crate or a merlin 454 crate for the same price...the gm is 502 horse n torque but was gonna change a few things before i dropped it in or the merlin with about 604 horse...but no more can be done to it fully built...

Thats going to be an animal of a car!!!!!!!!!!!!!!!

I'd say the GM Crate because they're more common, and probalby a longer warranty. Also if you ever decide 600hp isn't enough, you'd have to go forced induction for more power. i'd do the GM because simple bolt-ons would make crazy power on a 502. You'd put yourself well past 600 horse after a little money.

Either way is a good choice. But if I had to.... Hmm. I would go for the 502 GM motor. Just because of its greater displacement. However, the Merlin probably has better heads, the blocks are cast a little thicker for added strength and better cooling. The World block is going to be a better made engine, but for price to power I would go for GM 502. If money isn't an issue go for the Merlin block.

i was lookin at the merlin cause it actually has a better warranty n is dyno tested n tuned already...

the 502 i was lookin at is the best one they make...i figured i could work that motor a lil more but then i realized for the money i put in it i could buy a bigger merlin engine around 700 or more horse so im thinkin merlin
