The engine I'm using is in the car. The one I took apart is out, but it's so worn out it's not worth doing. Like I said, I will hang onto the other one and someday rebuild it proper (including a bore and new pistons)Quote from: Kitz Kat;253021Sure sounds like someone put a 86 block in it and used the e-7's.I think all the ho cams are pretty close to being the same it may be hard to tell the difference. I got some spec sheats I can check but I don't think it will help.I wish that were the case, because I'd at least be able to use the heads. This engine has E6's on it.Quote from: dominator;253028What a mess,i wouldn't trust that you have an HO cam thier either.The injectors should be orange top for stock HO(i have a set of 8 that i took out of my HO) tans are stock SO.You've got an SO that someone played around with,is it even a roller block???If it is it's .I have a 91 HO cam and a set of orange tops i can let ya have for 60.00cdn shipped if your interested(They came out of the 91 HO i put in my TC).According to Coolcats the 19-pound injectors can be either orange or tan, while the SO injectors are light grey. I confirmed that my 88's SO has light grey (almost white) injectors on it, and the ones on the other engine are definitely tan. Strangely, I can't seem to find any mention of tan injectors doing a Google search. Time to go pull one out. As for the cam, it is the HO firing order, so I must assume it's an HO cam of some sort (or, knowing how ized this engine is, a 351 truck cam)I might yet take you up on that offer, depending on whether I can figure out what I've got here.

Well, that was a disappointment... Reply #17 – January 22, 2009, 05:43:22 PM If it's a '86 HO, it should have E6ZExxxx on the piston tops... At least mine does...Tan or orange, one in the same 19lb(I believe they change color with heat)... The white/light gray are the 14lb, all SO 5.0, NA 2.3 and std 3.0 used these inj(no doubt a few others)...Quote from: BCA;25304030# - Red - Early 2.3L TurboNope, [COLOR="Red"]Red[/COLOR] inj are 30 lb, but were used in the '89-'93 3.8SC engine, plus are high impedance vs the low impedance 30lb [color="green"]Green[/COLOR] inj that were used in the early Turbo Coupes(and SVOs I believe)... The '94 & '95 SC used a 36lb dark blue high impedance injector injector, not interchangeable with the TC browns... Quote Selected

Well, that was a disappointment... Reply #19 – January 22, 2009, 06:01:55 PM OK, back in from the garage. When I unplugged an injector it was immediately obvious they are orange. The exposed area is just faded to look tan. The plug area didn't fade like I guess the exposed area does.As for the cam: I measured the lift using the very non-scientific method of using my digital caliper's depth rod. I rested the caliper base on a lifter, the depth rod on the dogbone, and zeroed it at 0 lift. I then turned the cam and took my highest reading, which was .24". That's pretty close to the .237 BCA quotes for a non-HO cam. Perplexed that I got the non-HO lift I checked the firing order again, by starting out with the #1 cylinder intake lifter just about to lift and then turning it, watching the order the other intake lifters lifted. I got the same numbers I got before.I then double checked on Mitchell. That's where my mistake was. I checked the firing order for a 1987 Mustang GT. Figuring that the program would actually give me the firing order of a Mustang GT I assumed my 15426378 was a match. Nope. Mitchell shows a non-HO firing order for the '87. When I checked '89 it gave the different, and apparently HO, firing order of 13726548.As for the pistons, I have not pulled them out. I stopped disassembling it the moment I realized it was basically the same engine I already have in the car (and given the ridges, I'd probably need a ridge reemer to get 'em out anyway). From what I can see they are perfectly flat except a very subtle dish in the center. I can't tell if they're forged or not, but given the non-HO cam and E6 heads I'd say it's a safe bet they're not. Final verdict: I've got a non-HO 5.0 with HO intakes and injectors. Oh well, like I said, the engine was pretty much a freebie. I'm glad I decided to take it apart before installing it :hick: Looks like I'll be needing a cam and some heads. Quote Selected

Well, that was a disappointment... Reply #23 – January 22, 2009, 06:35:14 PM The worst thing is I just three days ago sold my 351 for the money to do this thing. With the E7 heads :hick:And to add insult to injury, THIS shows up for sale locally. A bargain, but out of my reach at the moment. Unless one of you guys wants to lend me $850 PLEASE!!! I'll be your friend! Quote Selected
Well, that was a disappointment... Reply #24 – January 22, 2009, 08:10:24 PM Dam i need those heads,the rpm's would go perfect with my vortech.My performers are a little small but still function very well.850cdn is a killer deal for those,they'd be to much on a stock HO though,my performers would be better suited.Tell you what you buy those and i'll trade ya LOL JK...Still got that cam,in mint shape from a 100k HO.

Well, that was a disappointment... Reply #25 – January 22, 2009, 09:21:32 PM I'll let you know on the cam, I'm trying to track down heads right now. Those RPM's are nice, aren't they? I know they'd be too big for a stock 5.0, but then again, with those heads it wouldn't be stock If I could afford those I could afford a 347 bottom end and a decent intake/cam :hick: Quote Selected

Your problem would be valve clearance on the SO pistons... Quote Selected
