Well I know that the heater blower is all the way on the right under the dash. The wiring should exit somewhere under the center dash vents.



What exactly do you mean?

Don't do it man I'm warning you. Just kidding, but seriously you can't come onto a forum called "no pistons" and say that you want to rip out the rotary engine and drop an overdone V8. Besides it'll handle like crap. The factory rotary engine sits completely behind the strut towers. This promotes a nearly 50/50 weight distribution for the vehicle which is beneficial for handling. However if you drop a V8 in there, not only will you be adding a lot of extra weight to the vehicle, but you will also disrupt the near perfect weight distribution. I saw somebody put a 350 into a FC3 up in Dayton and the front of the engine was about 8 inches in front of the strut towers. The car was fast in the straight line, but when you have to turn there is so much weight up front that wasn't supposed to be there that the back wheels don't have enough weight over them when you stomp on the gas and oversteer is bound to happen. Just my thoughts but whatever you decide have fun with it and let us know how it goes.

Thats incorrect, the rotary engine, support equipment, and exhaust systems are heavier than they look. Typical weight gain for a 1st gen car is only 75-125 lbs. i have confidence that my handling will be fine.

But you have to think of the weight gain in terms of physics. The center point for the weight is a fulcrum and if you add a lot of weight over the fulcrum it isn't a huge deal, you might see minimal differences. However the farther away from the center point of weight you add weight, the effect is exacerbated exponentially.

ok since you would know about a piston engined rx-7,,, are u an expert?? Here are some real numbers from a typical RX-7 converted to Chevy power:

The example car is an ‘86, which was not lightened in any way. The car was converted using a ZZ-4 crate engine & T-5 transmission. It has a full stock interior, as well as the stock air conditioning and power steering. The stock RX-7 cooling system was re-located but retained, as was the stock RX-7’s engine oil cooler. The battery was relocated to rear area just in front of the tail lites. With a full tank of fuel, the balance is close to 50/50, 1535 lbs front / 1545 lbs rear, for a total of 3080 lbs (including the 200lb driver). Subtract the weight of the 200lb driver, and the total weight is 2880, 235lbs heavier than the RX-7's 2645 stock weight, and amazingly slightly less than the later Turbo II's stock weight of 3003lbs.

Geez I didn't mean to get your panties in a bunch but I'll put them in your purst next to your tampons! I was talking the 3 previous experiences that I have encountered in which all of the drivers had slightly regretted doing the conversion after seeing the results. They actually regretted it more so but wouldn't admit it because of the shot at their egoes or whatever bullshit. So good luck with the project ... expert, ha.
