Chevy V8 Swapped: 1985 Mazda RX-7

The first generation RX-7 (SA/FB built in Japan from 1978 to 1985) was a beautiful ballerina in the sports car world.  The RX-7's lithe frame was propelled by an equally dainty engine - the Mazda rotary...which was known for revvving high, consuming fuel, and sounding like angry bees when uncorked.  However, they are expensive to repair and many have (for better or worse) been swapped with another powertrain...and this next one is the most basic of swaps...Chebby V8 and 700R4 slushbox.  Find this 1985 Mazda RX-7 offered for $5900 in Caldwell, ID via craigslist. Tip from FuelTruck.

  1. Wasn't there a better solution than cutting the hood for that air cleaner? So close, and yet my old rule applies: if you have to cut the hood, it doesn't fit.

    1. I've seen that same air cleaner used - through the hood - on third generation RX7 V8 swaps too. There's not a lot of hood clearance for a carbed intake. Short of a very low profile EFI manifold like an LS1's, the only other option would be a scoop or cowl hood, unless you're able to get the engine a lot lower in the chassis than normal.
