I am looking into drivetrain ideas for my 1968 Mustang Coupe, I have about trashed my original ideas and have becone hell bent on creating a lethal machine that can match newer cars on their terms. However I want the nice amenitiaes, heated seats, A/C, Sterio, drivability, streetability ETC. I am looking into these options:

Custom build FE 390, stroked to 445 and producing at least 475 hp 510 ft/lb torque

Crate 351 stroked to 392 and producing 495 hp 495 ft/lb torque.

521 ci big block Ford Racing crate producing 500+ hp and 600 ft/lb of torque.

The 445 will work very well, its a 390 so AC kits ETC for a GT 390 will fit nicely.

The 351 is the easiest to find parts for, but AC etc may be more difficult.

The 521 is a monster and I doubt its street manners will be very good at all, but for $10k it MASSIVE power for your dollar.

Opinions? I want to run at least a 12, possibly a 10 and be street legal.

you might be surprised at how streetable a 500+hp 521 can be. personally that is the route i would go if i wanted a badass mustang.

I'd just do a stroked out 351w. 408 or 427 CuInch with Hi Port heads.

I'd be bored with 500hp myself. lol Takes nothing to make 500hp with a 408. Gotta make up for all that weight you put in the front with the 521, but then again it would be 650+hp with ease. Why settle for 500hp out of a 521?

running a 12 and then possibly a 10 are two different things. LOL Still should be no prob with a 408 on pump gas. 550hp and a decent suspension should run right close to 10.99's

Ford Racing build a 521 that produces 580hp and 600ft/lbs of torque for $10k

Survival Motorsports can custom build and dyno test a 445 with 490hp and 510 ft/lb of torque for just over $11k.

Im still looking for a builder for tha 351 based engines.

I wonder how hard it would be to setup AC for the 521, I suppose I couldnt use a kit and would have to build my own, with the 445 I could use the kit for a 390.

I just worry about the 521 being so heavy for the car.

I would have to second the stroked 351 route. As far as builders I highly recommend fordstrokers dot com.

That Ford Racing 427 sounds verrrrrry innnnnnteresting; when they start advertising aftermarket parts, they probably believe in them and put the "seal of approval" on their dyno specs.

However; that post just before this post spoke volumes with just two letters. Do a Google on the author's name..... you might read alittle bit about his avatar picture.
