New engine issues
Aj I have no idea what you are talking about ? Transfer slots? I haven't been able to drive the truck yet just starting it up and letting it run. The truck has 727 auto with stock converter racing shift kit and the rear is 8-1/4 with sure grip and 3:55 gears. Why do I need a 3000 stall converter? The pistons are aftermarket flat tops and is a little above stock = higher then 8.5:1
Well in post #1 you said 9.5 Compression ratio, now you say a little above stock. Stock was advertised as 8.0 and many members here say more like 7.8 .
when you go to give it gas it acts like it has the choke most of the way closed?
And here I assumed you were driving it. My mistake. But the end result is the same.
You said everything checks out, except the quoted part.
In my experience there are just three things that can cause what you are describing, which I'm assuming again; is a hard time taking throttle and a failure to rev up. And those things, again assuming you are correct in everything checks out OK, are: cam not properly synced to the crank, or intake valves not closing, or plugged exhaust.
The compression test will help with the diagnoses of the first two,and if very low, may lead to a Leakdown test which will prove one or all, of the three.
AS to the rest of my previous post, lets wait until the beast takes throttle.
