Today I tore into the short block and checked some of the rod bearings and this is what I found. First the good news................the crank is a billet SCAT................the bad news is that it will need to be turned..................probably about .010 under and I am not sure who to trust to do the work.................. The tranmission is with Mike's Transmission for a refreshen.............and the block will go into the machine shop next week................ Here are some of the pictures...........the bearings are stamped std., 1997, and the motor was put together by CHP in 1999...........so running this motor for 12 years..................well............it should have been refreshened maybe 6 years instead of waiting until 12...............still cheaper than building a new one.
Interesting. What kind of numbers were getting pushed from that 2-bolt? I'm not a big time racer, but those parts look big money to me. Kinda surprised at the 2-bolt stock block. Unless its not a stock block, then I will just feel silly. :16suspect
Looks fine to me. Slap it all back together and run another 10 years on it!!!! Run it til it smokes, is my motto. Or tosses chunks through the fenders.
Mercgt73, Well, the Maverick with me weighs in at 3375lbs and did a 9.801 at 133 in the 1/4 last year.....................figure is is putting down a little over 600HP to the rear wheels..........but that is a guess. When I get it back together I will chassis dyno the car to be sure and have some real figures..........the cam is 704 lift and the compression is 15:1. Remember this motor was put together in 1999 by CHP, and yes, the parts are high $$$$$ with real Eagle H Beam (before they started making them in China) and Probe pistons................The block is a good one, being made in 72.................71 to 74 are the best being heavier by over 10lbs than the newer 75 and newer..............all of the material in the older blocks are in the main bearing web area................in 75 there is considerably less material. Scooper77515, Since I've been racing for 30+ years I have always build motors to last. My first SS/IA car lasted 3 years of competition in NHRA with a motor build by Hatch&Park and trans by TCI...........so I'm not ready to waste a $2k crank along with a good set of Eagle rods (which are no longer made in the USofA) or the expensive Probe pistons..............and the block, well finding a pre 75 block is getting harder and harder to do.........plus costing $$$$ to get it prep'd................IMHO
So I should hold onto my original '73 302 out of my Comet. Thanks for the info, can't wait to follow the rebuild.
we have one like that too only its not so high dollar just a stock crank with eagle rods and dome pistons about 11;1 been together for about ten years also think it was a 74 block its seen 8400 quite a bit runs 6.30's in the eighth no nitrous or nothin amazing its stayed together but it has we did pull it apart 3 years ago just to look and it looked great so we put rings in it and put it back together with same bearings and all, still runs great it is in a 85 mustang coupe gutted so i dont know how much it weighs for sure
I was just messin' with ya! Those are quite respectable numbers, and a damned fine engine build, to hold up to that abuse!
Mercgt73, When I mentioned the good years............I meant 351w blocks, not 302's, although I have heard a couple of people say that the strongest 302 (other than the Mexican block) was the early 289's. I have seen one 331 bases early 289 that made over 500HP.................. Scooper77515, Gotcha! I was mess'en with you also.
Oh, ok. I missed the 351W part. I have a few of those laying around, I will have to check the casting dates on 'em. My Mustang II runs a 351W, cast ford heads, unknown guts. Never had it apart. Ran 11.0 @ 118, 2880 lbs with me in it. It was fun! Maybe my father and I can get back into racing someday... where can I buy about 2 ton worth of free time?
