We could always swap out whatever is in it for something cheap like a Chevy 12 bolt or a Ford 8.8. You could get an 8.8 out of an Explorer from a wrecking yard fairly cheap and it comes with 31 spline axles and disc brakes.

Whattaya think of an RX7 with a Ghetto-blown V8 and Ford rear end as a first project car?

Sounds fun except for the blower. With how light that car is a roots blower isn't a good match. Either go with a high winding N/A combo or a couple of small turbos. The one advantage of the SBC is cost of parts. You can get a complete rebuild kit from Summit Racing with 11.93 compression hypereutectic pistons from under $400 which would be great for a N/A combo. If you go the blower or turbo route you'll definately want forged pistons.

I like the idea of a turbo motor (cuz I want to learn about it). enkeivette suggested some old 6-71 or 8-71 off an old GM diesel. See here for more info:

Anybody have major objections to some kind of RX7 with some kind of SBC?

BUT!!!! They want to put a SBC in it. That just won't do. If we want to go fast we will need a FORD motor.

I've got a forged 302 long block with E7 iron heads, roller rockers , and a custom grind roller cam set up for a blower. It has the oil pan and timing cover for the old 60s cars. The engine bearly had 5000 miles on it when I pulled it for a stroked 347.

I also have a 4 speed toploader that will mate right up to it.

Other than test driving the original Mazda RX in HS, I don't know squat about them.(Still have the original 1st year brochure)
Are they unibody or frame? Morphing a car without a frame is tough. Chopping up the required room weakens them alot.
After trashing the driveline and rear, all you really have is a shell and front susp.
If it's a 75 or newer, which an RX7 is, it's gonna be a track car, since smog is totally out.
I wish Bob and I hadn't flipped his sons old race ready Vega. THAT would have been the catz azz. Stripped, tubed, tubbed, and reworked front and 9"rear.

Wish I could find those pictures. There is a guy in Frisco with big $$$ that stuffed a Jag V-12 in the front compartment of a Corvair. Outside looked completely stock. S C R E A M E R.

That reminds me of the best sleeper I ever rode in. I had an old friend who was a mechanic in Newport Beach at the Yacht yards. He put a buick V-6 in the back of a Fiat Station Wagon. Quiet exhaust. Whenever he was challenged, he was down the street before the other guy crossed the intersection. Bill was his name. HP/weight was unreal.
