Re: Ford 302 SS build
Yes you can run the 68 302 in SS/GT. I think you want a J code 302.I believe that engine allows a holley four barrel.

Re: Ford 302 SS build
No, you claim the engine as a j code and must adhere to the specifications for that engine. The people in tech check to make sure you’re legal, if they check.

Re: Ford 302 SS build
Ok thanks for the clarification i appreciate it! I’m just torn between running a 302 or a 390. Car is already set up for 302 and I don’t really feel like going through the troubles for big block swap.

Re: Ford 302 SS build
You can't get the Edlebrock Aluminum heads for the 390 any more so that combination would be out for me. The iron 68 heads are hard to find, but it's a good combo. The aluminum head 302 is easy to source parts. 64 289 rated at 203 is a good combo also. Your going to buy rods and pistons anyway, getting a stock crank done (from Castillo Crankshaft service which is near you) at a reasonable price.

Re: Ford 302 SS build
There's a reason no one is running the 69/70 302 2bbl combo, the HP is 220, the carb is 1.08 venturi rated at 287 cfm, jmo I looked at doing this years ago and my math says you'd be lucky to run the index.. however the 68 302 rated at 207 with 68 cast iron heads, 4bbl Holley, GT SS is a much better choice..Brian Seaberg 627

Re: Ford 302 SS build
What 351w would be able to make any power? Even the rare D0 heads flow same/less than gt40P's. They barely support a 302 let alone 351 inches.
Reminds me when Ernie Elliot built a 327" for restrictor races and qualified WAY WAY quicker, so nascar made the "minimum cu in" ruling. What secret am I missing where a top end that is barely enough to feed 300 cubes will run in a performance category with 50 more cubes? Edit: On Stan's site I checked out the basic heads from ford/chev/dodge. Mopar 051 head 1.88/1.60 (no idea if its good or bad) 50/49 113/97 165/123 188/123 193/137 Chev 462 1.94/1.50 (again no idea if this is a good head or not) 50/54 119/88 167/116 198/128 212/134 Ford E7 (as good as any and better than most stock ford heads) 1.78/1.45 52/39 95/74 132/98 143/104 159/109 To me, ford heads barely flow enough for 302's and once you see what 360's and 350's have for "base" heads, the 351W to me is way under headed. Richard Holdener ran a stock junkyard 302 and got 259hp and a stock 351 got the same but at a lower rpm which to me says as cast, stock heads will flow enough to produce 260hp and that's it. (for a base to start from) Am I reading something wrong?? Last edited by goinbroke2; 12-07-2023 at 11:23 PM. Reason: Confusion.. |

Re: Ford 302 SS build
I looked at the 69/70 351w combo because I have several mustangs, once again there's a reason no one that I know of is running this combo rated at 290 HP, I wanted to run it years ago because 69s are way cool but after doing the math I put it on hold, the rated HP is to high so I did a street bracket build instead..Brian Seaberg 627
