I have a 88 z28 and i got a 85 camaro i took the intake and carb off the 85 and put it on my 88 i cut the wires at the fuel pump and put in the machanical pump i know the mechanical pump work and every now and again it will blow a flame out the carb but it wont start i didnt mark the distributer when i pulled it out then i pulled the distruter back out and i did a compression stroke and think i brought it to tbc the piston was all the way up i put the distrubiter in pointing to cylinder 1 and the put the wire in from there now it wont start or blow a flame ou the carb

Without marking the dizzy, you have no baseline to start with....backfiring through the intake (after what you have done) seems like crossed plug wires somewhere.

 

FIrst, did you reuse the TBI Dist? Or did you get an HEI piece? Im assuming you got an HEI piece....

Check to see if you arent 180 out. Bump your #1 cylinder to TDC.....Take the #1 spark plug out and put your finger over the hole. Have someone BUMP the motor over with the ignition...best to take the Battery lead off the Distributor. When you feel it blow your finger off, look at the Harmonic Blancer and line up the slit/mark to "0" on your timing marker....thats TDC Compression on #1. Once you do that, take off your distributor cap and see if the rotor button is pointed at #1...if not, pull it out and take it to point to #1....if it is pointing at #6 you are 180 out. If it already points to #1, you are correct.

Once you've eliminated that, put the cap back on and double check your firing order and order of those wires. Once you do that and it sitll doesnt start, well good luck

My car spit fuel outand backfired real bad...I was 180 out...fixed it and it fired on first key and purred. Good luck with this.

 

yes reused the dist. from the tbi i am assuming i need to use the one from the carb parts caralso need to redo the tdc and bring the pulley to 0 with the timming cover

 

ok I got it to start and used a quadrojet carb the issue was the ecm was stuck open i got the timming perfect hears the thing you got to get it to 5000 rpms or so for the 4bbl to open and it runs really sluggish like it only running on 4 cyl. can anyone think of anything

 

Are you sure the metering rods in the quadra-jet are right. Sometimes people use larger ones if their motor is making more power than stock. That would cause you to run rich. Also, could you be a little more explanatory about the 5000 rpm remark. Is this when the secondaries open, or is it just when the engine starts to lose power? If it's when the secondaries open, you might want to break out the manual and make some throttle adjustments. The person you bought the intake and carb from, do you know if they were using a TH-350? This swap usually required a different throttle cable bracket. If you used that one, it might explain the late opening of the secondaries.

 

alright here is the new thing the motor is was ussing was nasty internaly so i pulled it out and put the motor in from the 85 i got when i opened it up it look like it had problally less than 5000 miles on it very clean still got some work to do to finish it up i should have it running by tomorrow and driving this week depending on weather
