Which CAR do you prefer? I had a Unique FIA with a stock 302 HO and we added alum heads to the motor. Sold that and ordered an ERA FIA with a KC 331 stroker. I prefer the FIA body - to me it's the "original" cobra and just looks better. As far as power in a SB, depends on what you're going to use if for. Daily driver and concerned about mileage?? (few cobra owners use em that way and aren't concerned about mileage). A stock 302 HO with a small cam gives you your torque in the 3000 rpm range so it accelerates quick, but will run out of steam at the high end if you want speed on a long straight (Sebring?). A 331 or 347 stroker will give you a lot of power and torque - kicks in around 3500 rpm (again depending on the cam)AND DOES NOT RUN OUT OF STEAM UP TO 6500 RPM. You can always go the 351 route (still a SB) and a stroked 351 (402 or 408) will give you 500 HP and a ton of torque. So I think the first question - especially if you're already ONE MONTH INTO AN ERA WAIT - is to decide on a body / chassis - as they are completely different ones.

Once you decide on FIA vs SC then you have a motor decision:

FIA - 302 variant (302 HO, 331, 347) or 351 viariant (351, 402, 408)
427 SC - 351 variants are very common (402, 408 even 427 using a dart block) or a real Big Block

That might impact your delivery date if you're going for a turnkey. My 331 stroker has AFR 165 heads and dyno'd at 436 flywheel hp at KC and 326 rwhp on a chassis dyno last week. If I had gone with AFR 185's it would have added 40 HP. The 331 has a nice power reserve and as far a "economy" can get 18.5 mpg on the highway. Enjoy your research. But the sooner you let Peter P know WHAT your are going to do the sooner you will get your car. Rickd
