Recently did a top end rebuild on my 95 GTS. Car has been sitting since Sept last year and started my project back in Mar/Apr.
Most everything bolted on top of the block is brand new. New rubber galore, new gaskets everywhere. Car is pretty much stock but am sporting Edelbrock Performer '60329' heads that originally came with the car. I also had them cleaned and resurfaced. I ditched my E-303 and added a nib Melling SYB-51 cam, along with their pushrods and lifters. The distributor is a new Cardone (not remanfactured) and also replaced the TIF sensor last year. In order to use the stock intake with Fox valve covers, I added a .5in phenolic spacer which prevented the EGR tube from reaching. ch so I bought some 5/8 brass compression sleeves at the local HW store and maguivered them onto both ends of the egr tube and tightened down. Its a perfect fit and does not appear to be leaking.
First startup - car runs fine. Ran it for about 40min at various rpms to break in the came. I can tell there is at least one rocker slightly out of adjustment 'ticking' but hasn't gotten worse yet. Next day, changed the oil and fired it up. It starts up and idles perfectly. Base timing was set to 10deg btdc. Also am currently running the Autolite 3924 plugs. So far have put about 20mi on it with zero issues, until today, 2 days later I started experiencing a stuttering effect when under load. Seems to be more prevalent under 3500rpm.
Things I have done
Pulled codes. Nothing. Just 111 'System Pass'
Checked for loose distributor, wires, nothing.
Checked MAF, nice a clean in factory air box
Checked EGR and holds when under vacuum
Things i have not done yet
Cylinder Balance Test
Fuel Pressure Test
Spark Plug gap ( i honestly don't remember what I set them too last year. I think .054)
I was planing having a shop look it for the rocker adjustment, but I might have them look at this too. Does not apear to prevent me from driving the car, but before i drive it any further, just curious what others have experienced after a rebuild or parts replacement that could be contributing?
