What motor would you choose? To put in a Z car.

The lightweight frame and suspension of the 240-280Z cars pretty much rules out any iron block v8. Beyond that, weight remains an issue. Even if you find a nice motor in your weight class, it may sit too high in the engine bay for the suspension and steering geometry to deal with. Pay attention to the CG as well as overall weight.

Don't laugh at this (too much), but there are loads of people taking old Dodge slant-6 motors and race-prepping them for small cars. The things have an unbelieveable amount of torque for their size and with a little forced air can really churn out the HPs.....

Check this out. I think the LS1/LQ4 could work. They are saying the the center of the engine is 12" behind the front axle. Also the cast 6.0l only weighs 100lbs more that the aluminum LS1. If I remember right the LS1 with a M6 weighs 503lbs. A t-56 can't be much more heavy.

Also check out this one. http://forums.hybridz.org/showthread.php?t=113156&highlight=ls1+weight

Or you could let me build you a really simple motor. I think it would look something like this.

^I think one might be in the works.
Just seen one that made 700hp stock longblock.

If there was a good deal on one, I'd go RB25 myself. Then just throw a 4088, or a 4202 on it, tune it, and call it a day.

LQ4 with spray. Done deal.
