Hello from newbie December 15, 2006, 07:15:19 PM Howdy y'all! I have an '87 Thunderbird,5.0,AOD. I have replaced the 7.5 with an 8.8 from a '88 LSC. The cam,intake and exhaust mani's are from the LSC as well. The ECA is from a '87 mustang 5.0/h.o.h.o. mustang h-pipe, lers and dual tails.I made the pipes between the h-pipe and lers on the pipe bender at work. I've tryed endlessly to get it to run right to no avail. I think my biggest problem is lack of compression. Any thoughts. Quote Selected
Hello from newbie Reply #1 – December 15, 2006, 07:36:05 PM Hello and wlcome aboard!!!check Your compression, normally the compression is around 150psi, if is below 100psi is BAD or if is very inequals, like 150-120-90-140 ect is bad too, need to rebuild the block...My 85 3.8 on My bird was these kind of compression last year, and for around 300$ on ebay, I rebuilted completely, now it runs great...

She is severly pregnant and moody though.Congratulations and Welcome!So what are the problems specifically that it's having running? Sounds like you did an H.O. conversion on the existing 5.0? Change to the H.O. heads? Swap the plug wires for the new firing order?You've probably already done and or checked this stuff though. Quote Selected
Hello from newbie Reply #8 – December 17, 2006, 01:31:53 AM yep! I suspect compession (ratio not static)because It has e6se heads on the dished SO pistons. It has very little acceleration and runs rich at idle. I have a marine 5.0 block that has only a couple hours on it. My LSC engine had a cracked block. The pistons are ok. I've been contemplating putting the HO pistons in the marine block (new rings and bearings). The marine motors heads have 'GT' in the corners (outside the covers) I've never seen that before, Are they any good? Quote Selected

Hello from newbie Reply #10 – December 17, 2006, 09:08:48 AM Youll have no issue with the compression ratio with the E6 heads and pistons.I doubt compression is your problem. Quote Selected

I have a heck of a time finding time to do anything. I had to rush wifey to the hospital today, Everything was fine and she's home. Just blew all my sunlight though. Oh. by the way, Merry Christmas!

Hello from newbie Reply #12 – December 25, 2006, 06:15:26 PM Well I checked it out with the snap-off scanner and there were no codes, yet it runs rich at idle. I don't quite understand how that is possible. It will burn your eyes if you stand behind it. I thought maybe compression ratio because the H.O. that the cam and intake came off had flattops and smaller chambers. Is the s.o harness wired different for the injectors than the h.o.?

Hello from newbie Reply #13 – December 25, 2006, 09:44:57 PM Cams and Computers... Could it be that you have a cam from a LSC and a computer from a mustang? did you get the computer from a musting with or without mass air?... do you have the correct injectors?do you have the correct firing order?
