I am pulling a F54 block and 5 speed tranny tomorrow (Sunday) Block and tranny is yours for the taking (free).........Just come and get it. Block needs new rings Tranny is perfect with new fluid and new clutch.

Summer motorcycle trip to the mountains :classic:

Head is yours Steve

I will sell the head complete .....I paid a little over $1200.00 for the work and parts....I will take $550.00 shipped....Like I said every peice in the head is new.(SOLD) I paid $185.00 for the Dizzy...It is brand new....I will take $100.00 Shipped.

I thought that i would give you guys first crack to make offers if you like. E88 Head..........Ported and Polished, Oversized valves, HEAVY springs, MS stage III Cam....Less than 100 miles on it. Brand new dizzy....the one for a 1980 280....with built in module e-1280 I think the module is (less than 50 miles) Arizona intake New holley 390....Less than 100 miles on it. Ms square port header....Less than 100 miles on it 5 speed tranny with New clutch and fresh oil change F54 block....In great shape just needs rings......(block is free...you must pick up)

I found the solution to my problem

All this work that I have done to my 78 280 and what do I get....Terrible dyno results Mod List The car already had a F54 block and flat top pistons I added E88 heads...ported and polished over sized valves heavy springs Arizona intake Stage III cam New Holley 390 Today I added a 2.5 inch exhaust flowmaster and a brand new dizzy and module for a 80 280. I am smoking at high RPM...Blue smoke...I guess I need new rings....I guess I lost alot of HP there. Dyno results 115 HP to the rear wheels 145 foot pounds of torque. I am bummed....all this work and money for such a shitty result.

I have a junkyard dizzy in my 78 280..... My advance is not working so I thought it would be a good time to pin the dizzy at full advance.....I plan on using a machine screw to lock it at full advance......My question is this. I have a timing light with the dial on the back. At what RPM do I need to set the timing? What setting do I need to set the dial at on the back of the timing light? How much before top dead center should I set the timing to? And last but not least...... Will doing this improve the performance of my car?

Oh yeah.....I have went thru 4 header gaskets.....leak kept comming back....this time went with felpro gasket and sealer....that puppy aint gonna leak no mo. The smoke has me kinda concerned though. Another concern is the oil leak....it is comming from the top of the timing cover where the head gasket meets the timing cover.............since that is not under pressure and is leaking from the chain spinning the oil around.....is there anything I can put on the seam to stop it from leaking.....I REALLY dont want to take this head off again.

Finally got her going....Ended up being a major vacuum leak under the Arizona intake.......................It was torked to hell....The only way to stop it was use some gasket sealer....I dont like using that stuff on an intake but it did the trick. It does not have the power that it should...but it does run very smooth.......from here on out it is the easy stuff..............hot valve adjustment.....fine tune the timing and carb. I am going to have to pulle the timing cover one more time ( I hope not the head) From the timing cover being taken on and off so many times, I have a small oil leak at the top of the timing cover)......I hope a little gasket maker will do the trick....I really dont feel like pulling this head again. I have some blueish smoke under heavy excell ...... God I hope my carb is just rich.

I was having a cup of cofee this morning thinking what the problem could be.....................Cam across some info on ignition systems. From what I gathered with me converting my 78 to a holley carb that I could not use my stock dizzy and ignition module....I had to find them from a 79 or 80 with the module on the dizzy......I thought my problem was solved.....went to a junkyard....bought the parts off of an 80.....mounted them up and what I have a a high $$$ peice of $^!# motor.............Still runs like crap! Just venting Jeff

I thought the Holley would make things simpler.... I agree that the comp. is High....I know what I have done to the head....I dont know what the previous owner has done to the bottom...he is dead. The valve timing will be done once more this week (not by choice) My 9 year old was holding the light and knocked a screw down into the timing cover. It does not get any better than this. I can only laugh at this point. HA HA

yes....still popping fuel back just not as bad.....I have a light...would be hard to use though because you cat keep the car at a constant rpm

OK....here is where I am now. I can get the car to start a little easier.....still will not idle and you have to constantly feather the gas to keep it running (running very rough I might ad) One thing it has started to do..................While feathering the gas it will all of a sudden RACE to a very high RPM until the excess gas burns off......over and over....feather the gas....give it more gas let off the gas and she runs up to a high rpm from the previous gas pushing.....any ideas? Am I getting any closer???

Comp. results Less than 6 revolutions 180-190 per cylinder If you let it turn over and build max pressure it builds to and holds 230 to 235 psi What does that mean?

In regards to this 180 out thing......If I put the motor at top dead center and my rotor is pointing at the #1 cylinder....isnt it impossible to be 180 out?

I am grasping for straws here. Just a reminder: 78 280Z removed the stock head, fuel injection,cpu, and wiring harness Mounted an E88 head Arizona intake Holley 390 For the 4th time......I pulled the the timing cover and chain off ( even bought a new timing set) Crank and cam are set on the money Dizzy is on the money firing order is on the money. I can get the car running but you have to pump the gas and keep the rpms high.........keeps kicking gas back thru the carb. All point to the timing being off.....BUT it is not! Here is my only thought.................. When I removed the wiring harness did I remove something to the ignition module? Does this car have an ignition module? Since I have the stock electronic dizzy did I need to run the 2 wires from the dizzy somewhere else after removing the comp.? When the 240 or 260 guys install a late model electronic dizzy on there car where do they run the 2 power wires to? Do they install an ignition module? Please give any suggestion that you can......I am all out of ideas.

yes its true........................................................ Bought a new timing set and gonna break her down and start from the beginning one last time. If she dont start there will be a few things for sale. F54 block with flat top pistons and low miles Heavily modded (port & polished, oversized valves, heavy springs,Hot cam) E88 head. Arizona intake new holley 390cfm New square port MS header Keep an eye on this thread I am a very calm man.....dont get pissed about much but this thing has put me over the edge. If she dont run this weekend I have a 400 SB that I am gonna start prepping Jeff
